And today’s you ask. I answer, asking the question, what does data driven mean? So here’s the way I explain data driven. Most of us have one of these things, right? As a map application on there, some kind of Google Maps Apple Maps, whatever. How does that work? How do you use it? Do you just get in the car, start driving and see what the app tells you?
Maybe, you know, there there are people who like to do that kind of exploration for most of the time to use that tool. We open it up. We set a destination and then we hit Go, Hit Start, and the software looks at all the possible routes to get from where we are to where we want to go and takes into account things like traffic, road closures, et cetera, and gives us a recommended route That is literally being data driven.
You are being data driven when you set the destination and then the machine helps you navigate. Now, notice that the machine doesn’t do the driving for you, right? You still have to get behind the wheel is for now as self-driving cars improve. Obviously that may change. But for today, in 20, 22 you still have to do the driving.
You still have to set the destination. But the machine guides you on making choices. And sometimes those choices, you may know better, right? If you’re just using the app locally, you may know, oh gosh, actually that route that you picked is technically shorter, but it’s an unpleasant drive. I’d rather take the slightly longer, but that’s less efficient. But a much more pleasant drive.
Right? Or Hey, I know that that road that you say is closed is not actually closed. And so you may make different choices, but especially when you’re in a geography that you don’t know, being data driven in this example means you put in the destination, you let the machine guide you, right? You make your choices based on what the machine tells you based on its data.
When we talk about being data driven in business, in marketing and strategy, that’s what we mean. Mean the data that you have should be able to tell you, here’s what’s likely to happen. And the best recommendations for moving in the direction you want to go. This presents some rather difficult challenges, doesn’t it? Because last I checked, no software that we use actually gives us driving directions, right?
When you open up Google Analytics, it doesn’t tell you what to do with your website. Right? When you open up your marketing automation software, it doesn’t tell you what to put in your next newsletter. And so even though we will talk about being data driven and even though analytics companies and analytics software will say, adopt a data driven mindset, it doesn’t match up to what is actually being data driven.
Right? Because unlike a GPS, none of these pieces of software acts like a GPS. They don’t tell you what turn to take next. You know, the destination you want to go to, right? You know, you need 10,000 marketing qualified leads or $100,000 in pipeline or whatever the number is. You know where you need to go but the promise that we’ve sort of established from the discussions about being data driven versus the reality are pretty far apart.
We don’t have much that allows us to be data driven, not in the truest sense of turn right now we’re starting to we’re starting to predictive analytics in particular, starting to get to a point where there’s more guidance right? If you have things that are cyclical and seasonal, you can use trend analysis and forecasting to make decisions and predict what’s likely to happen coming up.
But it is early days for that, right? It’s very, very early days. And the reality is right now it’s inaccessible to a lot of people. When I put together my content calendar, I used predictive analytics. I use forecasting. Here’s what the terms that are likely to be trending in the next week or month or whatever but that’s with software that I wrote and data sets that I ingest because I wrote software to to to get those to.
That’s not something that is universally available to everyone. And so I would argue that very, very few folks right now are data driven, not because they don’t want to be, not because they are doing something wrong, but because the tools don’t allow them to be data driven. There is no such thing as a marketing G.P.S. or a strategy or a financial G.P.S. that says make this decision next turn right here doesn’t exist.
Will it ever exist? I don’t know. It depends on how complex the models are, how much data they can ingest and how intelligently they can pass it.
But at the very least, it’s safe to say that for today, there isn’t much that allows you to truly be data driven right. So even though we have data and we have strong analysis and we have maybe some insights for market research, we don’t really have a ton of things that allow us to be truly data driven. We don’t have somebody or something saying, turn right here, When you address a vendor that is talking about how their software helps you be data driven.
Bring out that mental model of the map application on your phone. If I put my destination here, will your software tell me where to go Most software vendors, if they’re honest, will say, No, no, it doesn’t do that. It can give you some insights. It can tell you what happened. It can hint at things, but it’s not going to tell you which direction to go or when to do things.
That is still a function that is reserved for us as the decision makers. And it’s one of the reasons why a lot of the time when people ask, Is I going to take my job now? No, it’s not. Not if you’re good at your job because you still got to do the driving and you still got to set the destination and today you still have to decide what turn good decision to make turn by turn, because the software doesn’t tell you that.
Software tells you how far you’ve gone, how fast you’ve gone, how fuel efficient you’ve been. But that’s it, right? Most analytic software is rearview mirror only, and there’s not easy off the shelf solutions to be data driven. Again, it can be done, but it requires fairly technical teams and it requires access to data and knowing what you’re doing with it.
So it’s a challenging question. What is data being data driven mean? And the reality is that most of us are not, and that’s OK for right now. But know that that’s the goal. That’s where we want to get. And the first company in your sector, in your space that gets there is going to go really, really far, really quickly.
So our aspiration is to be that company so that we can do very well for ourselves. Thanks for tuning in. We’ll talk to you soon. If you like this video, go ahead and hit that subscribe button.

Paul asks, looking back on the way you learned about AI, is there anything you wish you would have figured out first? Yes.
So machine learning and data science really are a blend of, of four different areas, right.
So there’s the business side, it’s the business problem, the the business strategy you’re trying to solve, there is the data engineering side, which is handling data.
Storage, being able to, to retrieve and rank an index data this that you have stored, there is the coding side, where you have to be able to read and write code in a language like R or Python, which would allow you to be effective.
And then there’s the mathematics, you know, statistics and probability side, knowing the advanced mathematics, so that you not only know what the machines are doing, but you know why, you know why certain algorithms make for better or worse fit, certain techniques make it for better or worse fit.
And when I look back, I’m self taught on a lot of this stuff.
So I have a lot of gaps.
In my knowledge, particularly on the mathematics side, I can patch gaps pretty easily on the code side, I know the business side.
I know the data engineering side fairly well actually, because I have an IT background, but my my weak spot, my blind spot really is on the mathematics side, particularly once you get into stuff like linear algebra and things like that.
Higher level mathematics, that’s when I feel the biggest gaps.
And so from a professional development perspective, certainly, that’s something I wish I had known, more of going into this.
And certainly something that I’m spending a lot of time nowadays, trying to remediate so that it’s not as big a weakness, right? It’s not as big of a gap.
do a self assessment in those four areas and figure out which area are you weakest in? Which area are you strongest in, and then try to patch those weak spots, particularly if you’re still in school.
Definitely take the time to patch those weak spots, take an extra course in something that you know you’re not good at.
So that it’s less of a vulnerability or added also it’s at the very least, you’re not going to be paying a lot of money to an institution to later on to reteach you something you have to learn the first time around.

How much data do you need to effectively do data science and machine learning?
The answer to this question depends on what it is you’re trying to do. Are you doing a simple analysis, some exploration to see what you might learn? Are you trying to build a model – a piece of software written by machines – to put into production? The answer depends entirely on the outcome you’re after.
Here’s an analogy. Suppose you’re going to bake cake. What quantities of ingredients do you need?
Well, how many cakes are you going to bake, and how large are they? There is a minimum limit to quantities just for the basic chemistry of baking a cake to happen at all, but there are cakes you can make that are disappointingly small yet are still cakes.
Are you baking a round cake? A sheet cake? Ten sheet cakes? How quickly do you need them?
You start to get the idea, right? If you need to bake 100 cakes in 24 hours, you need a much bigger oven, probably a much bigger mixer, perhaps an extra staff member, and a whole lot of flour, sugar, milk, eggs, and baking powder than if you’re baking a single cake.
The same is true of data science and AI. To do a simple exploratory analysis on a few Tiktok videos requires relatively little data. To build a model for the purposes of analyzing and reverse-engineering Tiktok’s algorithm requires tens of thousands of videos’ data, possibly more.
Some techniques, for example, can use as few as a handful of records. You can do linear regression technically with only three records, that’s the bare minimum amount you need for a simple linear regression to function. Other techniques like neural networks can require tens of thousands of records just to put together a functional model. That’s why it takes some experience in data science and machine learning to know what techniques, what recipes fit not only the outcome you have in mind, but also what ingredients and tools you have on hand.
There’s no firm benchmark about how much data you need, just as there’s no firm benchmark about how much flour you need for a cake. What is necessary is understanding the outputs you’re trying to create and then determining if you have the necessary ingredients for that output.

Without fail at nearly every marketing conference, someone rails against vanity metrics. Stop measuring them. They don’t matter. They’re the devil. Variations on those themes. So let’s clear the air a bit, because just as some people put too much importance and faith in vanity metrics, other people discount them too much.
What Are Vanity Metrics?
The generally accepted definition is that vanity metrics are metrics that make you look good but don’t lead to the outcomes you want.
When asked, people refer to the following as examples of vanity metrics:
Likes
Shares
Comments
Followers
Open rates
Views
Page visits
etc.
What do all these have in common? They’re all very much top of funnel metrics. And to be clear, when we say funnel, we’re talking the marketing operations funnel, the way we organize our marketing internally. Customers don’t follow a funnel, but we have to if we want to stay organized.
Why Are Vanity Metrics So Over-Reported?
The trend among marketers, particularly around the start of the age of social media in the mid-2000s, was to report on audience numbers like followers as an outcome. Why? Because at the time, we had no better ways to measure the results our marketing generated. Remember that even tools like Google Analytics didn’t have any kind of assisted conversion tracking until 2011.
Vanity metrics are the legacy of marketing that saw strategies and tactics vastly outpace measurement. They’re the numbers that were accessible at the time, and even today, they’re the numbers that are easiest to report on.
Why Do Marketers Hate on Vanity Metrics So Much?
This one’s easy. Performance-focused marketers dislike vanity metrics because of how distant they are from marketing KPIs, especially in complex sales. Consider the chain of interactions that the average marketer should measure:
Awareness measures: vanity metrics!
Consideration measures: returning visitors, branded organic searches, newsletter subscribers, etc.
Evaluation measures: marketing qualified leads, shopping cart starts, contact us form fills, etc.
Because vanity metrics are so far from the outcome, it’s difficult to determine if they matter at all. As such, marketers tend to spurn them.
In terms of analytics sophistication, this isn’t necessarily the worst thing in the world. It’s an improvement over the last couple of decades; marketers focusing on real outcomes that yield business results is a good thing. We shouldn’t stop that. Keep focusing on the outcomes you get paid to generate.
But hating on the top of the funnel is illogical. If the top of the funnel is empty, the rest of the funnel doesn’t matter. If we have no audience, we cannot create consideration because no one is paying attention to us, and that means no evaluation, and no results. So we know logically that vanity metrics have to count for something, because if they were zero, our marketing would also be zero.
Do Vanity Metrics Matter?
Here’s the challenging part, the part that will highlight your progress towards marketing analytics maturity.
Most vanity metrics don’t matter.
Some do.
And you can’t determine which do and don’t by eyeballing them. The only way to tell the difference between metrics that matter and metrics that don’t is through math and statistics.
Vanity Metric Evaluation Walkthrough
Here’s an example. We’ll start with Google Analytics data – users as my main metric, goal completions as my objective that I care about, and then every source/medium combination for the year to date:
Next, I’ll add in social channel performance data from Agorapulse, both at the content level (individual post performance) as well as account level (followers/engagement performance):
And then I’ll add in YouTube data and Google Search Console data, yielding what’s effectively a very, very large spreadsheet with 98 columns:
Here’s where the math part comes in. We could manually write out all the code needed to test every possible regression algorithm against the dataset, but I like my sanity. So, using a tool like IBM Watson Studio, I’ll have a machine do all that testing instead, building model after model to find the most accurate description of what predicts goal completions.
Pause for a moment and give some thought as to what metrics you think will make the cut, that will show real value, real impact on our KPI.
Ready?
What we’re looking at here is a variable importance model; it describes what variables in the dataset have the greatest importance, the greatest contribution to the outcome I care about. Topping the list is Google Search Console impressions – the more my site shows up in search, the better. The second is overall Google Analytics website traffic. And the third…
…is the number of Twitter followers I have.
The ultimate in vanity metrics, one inveighed against mightily for years. And yet, in this mathematical model, it has more relevance to my outcome – Google Analytics goal completions – than many other variables.
Key Takeaways
Now, to be clear, this is a regression analysis, which means this is correlative. This doesn’t prove causation, but it does set the ground for testing, for designing experiments that can help prove causation. After all, this could be reverse causation – as my site engagement and conversions go up, people might naturally find their way to Twitter and follow me there.
How would I design those experiments? I might conduct an organic follower growth campaign, or even spend some money on a paid followers campaign. If, as followers go up, my conversions also go up by the same proportional amount, I’d start chipping away at causation.
But the key to remember is (for the most part) if there’s no correlation, there’s almost certainly no causation. So at the least, I cannot dismiss Twitter followers as purely a vanity metric outright for my marketing. Facebook fans? Sure – they didn’t make the top 25 in terms of variable importance.
And keep in mind – this is unique to my website, my data. This is not at all a proof point for anyone else’s data, so don’t think just because my outcomes have Twitter followers as a component that yours do too. You must do this analysis with your own data.
Here’s the most important takeaway: you cannot assume you know what metrics matter and don’t matter. You must evaluate them with some kind of mathematical model to determine which ones really matter. Only after you’ve done a model can you truly choose what matters and what doesn’t in terms of reporting and focus, prove causation, and then start building marketing strategy around your metrics.

One of the truths we don’t talk about nearly enough in marketing data science is the need to blend data. There are very few data sources that are a single source of truth by themselves, that need no augmentation or supplementation to provide maximum value. Even our most favorite, most used tools like Google Analytics, Hubspot, Salesforce.com, etc. lack data that would make them truly comprehensive.
Why is Data Blending Necessary?
Why? In many ways, the evolution of these tools means they should be growing more focused, not less – and adding more data that isn’t broadly applicable. is the wrong path to go. As a result, point applications like SEO tools or nurturing tools crop up to fill those gaps – and that’s okay. Just as the major tools do, these new spot applications become experts in their little niches as well, allowing them to iterate and improve quickly.
Except… they have their own data. Which then means we have to learn how to blend data. This isn’t anything new – if you’ve ever used any of the lookup functions in Excel like VLOOKUP or XLOOKUP, you’ve done data blending. Applications like Alteryx and IBM Watson Studio Data Refinery have existed for years that streamline data blending for larger enterprises. New applications on the market like Tableau Data Prep allow smaller companies to access more of these capabilities. Open-source data languages like R and Python make data blending free and relatively straightforward to anyone with the skill to write in them.
But regardless of the tool, data blending is an essential skill for anyone working with marketing analytics data.
What Is Data Blending?
First, let’s be clear: data blending is a stupid name. When we think of a blender, we think of a device where we put a bunch of ingredients in and get a mashed, mixed version of them out. Put a bunch of fruit in, get a smoothie. Put a bunch of kale in, get a bowl of sadness and regret.
Data blending is nothing of the sort. You can’t just put a bunch of data in a machine and have a data smoothie come out. Well, you can, but you really shouldn’t, since it has absolutely no utility that way. But we’re stuck with the term for now.
So what IS data blending?
Data blending is the bonding of two or more data sources together, often to create analysis or insights you can’t obtain by looking at one data source, or looking at data sources separately.
The key ingredients to data blending are rectangular data and keys. Let’s examine what these mean.
Rectangular data means data that is in some kind of table format, like a spreadsheet or a delimited text file.
Rectangular data has specific requirements- it’s data that has distinct columns and rows, with rows and columns being of equal length. For example, you can’t have one column with 72 rows and another column with 15. In data science, you’ll often hear these tables of data referred to as data frames.
Keys are values that different tables have in common.
For example, suppose you have an export from Google Analytics and an export from your social media monitoring software. Both tables have lots of data in them, but they have a column in common – the date. In this case, the table key would be the date.
Or, you have data from your marketing automation system and your CRM, and both have the customer’s email address in common. In that case, the key would be email.
Keys are essential for data blending because they’re what allow you to glue together two or more data sets. As long as the keys are identical in terms of format, you use them to merge data together.
Data Blending: SEO Example
Let’s look at a practical example of data blending. Here’s the data I get from Google Search Console about my website:
Alone, there’s a good amount of information here, information I could use to make decisions. We see each page on my website, the query that Search Console says that page is being found for, the number of clicks that page and query combination have received, and a few other metrics.
Could I build SEO strategy just from this list? Could I make decisions just from this table of data? Yes, of course. I could look at this and determine what I’m getting the most clicks for, or look to see how often I show up for terms that have a lot of impressions, but not a lot of clicks.
But something’s missing. Search Console shows data that is specific to our own websites. I can’t see how many people search for something like ethics in marketing, just the number of times my site has shown up in search results (that’s what impressions means).
Does that data exist? Yes! It exists in the SEO tool of your choice.
If I export all the queries Google Search Console says I show up for and run that through the SEO tool of my choice, I can now see how much any given term is searched for overall, whether or not my site shows up for it.
If we think about this in terms of addressable markets, then what comes out of Search Console is my obtainable market – the searches that my site could plausibly obtain. What comes out of my SEO tool is my addressable market – the maximum amount of overall searches for a given term.
Which means, if I could blend this data together, I could see what percentage of my addressable market I am currently obtaining.
Look carefully at both tables. Do you see the key? It’s the query – both tables have query in common. With that, we can join them together.
I’ve now got my data, joined by the query key, all in one place, all in one table, which means I can start doing math on it. Let’s do that computation – my site’s impressions for a given term divided by the total number of searches for that term, to see how much of the market I’m addressing.
For the most part, I’m showing up for less than 10% of most of the terms. That means in terms of upside, I’ve got a lot of potential still. I haven’t tapped out these specific terms. If I was capturing something like 80-90% of the volume? I’d be hitting diminishing returns on my optimization efforts for those terms and topics.
What decisions could I make with this data? If I brought all the data into a common, shared set of measures – like a 0 to 100 score for each column, where 100 would be high opportunity and 0 would be low opportunity, I could build a prioritization score:
What does this merged score tell us? These are the best balance of opportunities – search volume, likelihood that someone will click on my stuff specifically, appearances in search, keyword difficulty, etc. By merging everything together and reducing it to a single score, I can now use that score to make decisions. The pages with the highest score need love. They need to be optimized and tuned, linked to, shared, the works. Anything older than a year probably needs to be freshened up and augmented.
We couldn’t get to this level of insight without data blending. By merging two datasets together, we gained greater view of our search opportunities and built a straightforward rubric to make decisions.
Bear in mind, this still isn’t the whole picture; there are even more things we could do with additional data blending, like bringing in competitive data, but this is sufficient to illustrate the point.
How To Get Started With Data Blending
Start simple. Learn how to use functions like VLOOKUP and XLOOKUP in tools like Excel and Google Sheets. That’s the easiest place to begin; from there, you’ll explore more advanced tools until you reach the point where you start writing code for truly customized data blending. As your skills and knowledge grow, you’ll be able to take on bigger and bigger datasets until you’re blending incredibly complex amounts of data and generating insights no one else can.

Kate asks, “Why do you have such a fixation on data?”
This is a more interesting, philosophical question than it might first appear. Yes, I emphasize data a great deal in my work; my company, Trust Insights, is rooted in data-driven marketing. But where did this all come from?
A significant part comes from my faith, from my spiritual practice. I’m Buddhist, and that faith aligns with my perspective on the world.
The Four Noble Truths of Buddhism
Buddhism has a fundamental core teaching, something called the Four Noble Truths. You can read any number of academic texts and scholarly interpretations, but the lay explanation I give is basically this:
Life sucks.
Life sucks for a reason: wanting things to be different than they are.
There’s an achievable way for life to stop sucking.
The way for life to stop sucking is to stop wanting things to be different than they are.
Any number of Buddhist priests and scholars will correctly argue this is a vast oversimplification of a teaching that’s thousands of years old and can run as deep as the ocean, but it’s how I think of them in practical terms.
We know these truths to be, well, true. Think about any situation where you’ve been unhappy, and at the core of that situation is the desire to want things to be different than they are – a sick loved one, a broken heart, bills piling up. The unhappiness you feel comes from wanting reality to be different than it is.
Now, that doesn’t mean you simply give up. It does mean you accept the situation for what it is so that you can stop being paralyzed by emotional turmoil or expending energy denying the problem and start finding your way out of the situation towards something better.
Buddhism and Data Science
What does this have to do with marketing data science and my love of data? Data – when it’s correct – is our best objective representation of reality, of figuring out the way things are so that we can accept reality. Once we accept reality and stop denying the way things are, we can start down the path of making changes to that reality.
That’s why data and data science are so important to me. Correct data helps us start down the path of accepting what is. We can have opinions about what marketing tactic or strategy is working, but when the attribution analysis rolls out and we see our favored method falling to the bottom of the list or not making the cut at all, we have to acknowledge that it’s not working.
And like ourselves, data is never perfect. There’s always more to gather, more to refine, ways to improve its quality, ways to remove unnecessary elements, misconceptions and misunderstandings to dispel. Data can always be better – and so can we.
Why People Sometimes Struggle With Being Data-Driven
This is also why so many companies and so many individuals struggle with becoming data-driven. It isn’t because you can’t do math. It isn’t because you have zero data. It’s largely rooted in the fact that becoming data-driven means accepting reality as it is currently, and sometimes that reality sucks.
Being data-driven sometimes means saying to your stakeholders, “yeah, we really screwed up this quarter and the numbers are way below our goals“.
Being data-driven sometimes means saying to yourself, “the thing I love, the thing I’m good at, isn’t working“.
Being data-driven sometimes means admitting to your peers, “the thing I’m supposed to be good at, I’m objectively not good at based on the results I’ve generated“.
These are realities that it’s easier and less emotionally painful to gloss over, to ignore, to deny. We’re wired as animals to seek pleasure and avoid pain. When something sucks, when things are going badly, it hurts – and we want to avoid that hurt in the moment, even if it compounds the pain later.
And in some companies, in some cultures, it’s not only easier to deny reality, but sometimes it’s demanded of us. The boss who ignores any report that doesn’t make him look good. The investors who demand only numbers they like.
But denying reality has consequences. In the end, reality always wins.
Should You Love Data?
I say all this to answer Kate’s question. This is why I have such a fixation on data. Data – correctly gathered, understood, and used – is a path towards more truth, even if the truth isn’t positive sometimes.
Once we accept the truth and stop wanting reality to be different than it is, we stop hurting as much. We reduce our frustration. We feel less anger at wanting things to be different than they are – and what emotions we have, we more capably redirect. Instead of denying what’s in front of us, we free ourselves to ask, “Okay, how can I make this better? I accept what is, so what’s possible to change for the better?”
If I accept the truth that I suck at Facebook marketing, that I just can’t get results out of it, then I am free to decide whether I want to improve that set of skills. I no longer have to struggle against the reality that I am unskilled at Facebook marketing, and taking that struggle away frees me.
That said, just as Buddhism isn’t the right spiritual calling for everyone, being data-driven isn’t the right path for everyone either.
If you work in an organization that actively denies reality, being data-driven will only make your work harder.
If you work for a person who prefers comfortable lies over unpleasant truths, being data-driven will be a source of unhappiness to you.
If you work in a place or for someone that encourages people to believe in less truth, in less reality, being data-driven will make you miserable and probably get you fired.
I encourage you, obviously, to consider changing who you work for and what you do for work if you’re in a situation that is so diametrically opposed to reality, but also recognize that sometimes, the choices we have in front of us aren’t good, and there’s merit in patience, in waiting to see if things improve as long as you’re not enduring harm.
If you are enduring harm, I would encourage you to accept that reality (instead of pretending everything is fine) and free yourself to start making a change for the better.
In the end, reality always wins. I encourage you, no matter where you are in your pursuits of becoming data-driven or what your personal faith is, to keep striving for more clarity, more truth, and more acceptance of the way things are so that you clear a path towards better days sooner.

I am bearish on AI creating GREAT content at scale – or at all.
Why? It comes down to limits of training data, fundamentally.
All machine learning models, from the most basic to the most sophisticated, need something to learn from. In the case of language generation – automated creation of content – they need tons of examples to learn from.
And therein lies the problem.
Before we go farther, let’s define great content as content that’s well-written with a unique point of view and a distinct voice. That part is important.
Content Quality in the World
When it comes to publicly available content, there are two potential distributions, a power law distribution and a normal distribution.
A power law distribution looks like this:
This is also known as an 80/20 rule or a 95/5 rule; fundamentally, the amount of poor quality content dwarfs everything else. The amount of great quality content is on the right hand side – and it’s very small.
A normal distribution looks like this:
In this case, it says there’s a small pool of absolutely terrible content, a massive amount of mediocre content, and a small pool of absolutely great content.
Whichever distribution we think represents reality, there’s very little great content compared to everything else – which means machines have very little great content to learn from.
And if there’s an insufficient amount to learn from, then the machines will not be able to synthesize great new content. They will be able to synthesize mediocre content or poor content.
How Much Content to Train?
How much content are we talking about in order to train a natural language model? The Pile, an 800 GB dataset created by Eleuther.ai, is a training dataset composed of 22 libraries:
The largest item in The Pile is the CC, the Common Crawl, derived from the Wayback Machine and Archive.org. That means it’s ingesting a huge amount of web text from all over the web – and of substantially varying quality. OpenWebText2, according to the documentation, is another scraping of web content based on Reddit upvotes.
All this indicates the level of quality of the training data. The folks who assembled this training dataset, like the other major natural language models, have done their best to filter out the bottom of the barrel, the absolute garbage that would do more harm to a natural language model than good. So we can be fairly confident in a normal distribution in terms of content quality; after all, YouTube subtitles, US patents, and medical papers are important documents but not exactly riveting reading most of the time.
What isn’t obvious from the table above is just how little data we have for a specific example. The Common Crawl is 227 GB of data, with an average document size of 4 KB. What that works out to is a dataset of 56.7 MILLION pages. That’s how many web pages are needed in just a portion of the training set.
The overall dataset is 825.18 GB, with an average document size of 5.91 KB. That’s 139 MILLION pages of text. That’s what is needed to construct a language model.
Now, let’s say for giggles that you think your website is the bee’s knees, that your content is A+ content. Let’s use Social Media Examiner, a well-regarded blog, as an example. How many pages are on this site? About 62,000 per the AHREFS SEO tool. When you think about it, that’s a tiny amount of text. Even the Reddit-filtered OpenWebText2 portion of the pile is 16 million pages.
In terms of a unique voice, let’s use this blog. I’ve been blogging here consistently since 2007. How many pages of content have I managed in that time? 8,954. That’s not a ton of content in the big picture compared to what is used to train machine learning models.
Which means that natural language models will inherently be biased towards creating mediocre content, content that’s readable and coherent, but not compelling or unique, because that’s what the vast majority of the language is that they are trained on.
An Example
Let’s illustrate the limits of language models trained on a diet of mostly mediocre data. First, let’s take a mediocre use case – writing a press release. I’ll feed the GPT-J-6B natural language generation model the following text from a press release:
NEW YORK–(BUSINESS WIRE)–Today, Effectv, the advertising sales division of Comcast Cable, released the latest edition of its TV Viewership Report. The report explores viewership trends for the first half of 2021 based on Comcast aggregate household viewership data, as well as insights based on Effectv’s campaign ad exposure data for both traditional TV and streaming content.
According to an analysis of more than 20,000 Effectv cross-platform campaigns, streaming consistently served as a strong complement to traditional TV campaigns in the first half of 2021. In fact, 57% of reach from streaming in those campaigns was incremental to linear TV campaigns. Additionally, streaming impressions were +209% more likely to be served within households that viewed little or no traditional TV. This proves that complementing traditional TV strategies with premium long-form streaming will grow incremental reach and increase exposure with households less likely to be tuning in the traditional way.
This is only half the press release; I’ve highlighted in yellow the part I’m feeding the AI:
I want the AI to autocomplete the rest of it. Let’s see how it did:
“Our data shows that traditional TV and streaming are complementary platforms, which is why we’ve invested so heavily in both,” said Mark O’Neill, senior vice president, Ad Sales. “We’re seeing strong results with streaming, and we look forward to sharing more insights at the upcoming IBC in September.”
Viewership Trends
TV Viewership Trend Analysis
With the recent U.S. restrictions on travel and gatherings, viewership of national, regional and local channels has been declining in most markets. For those channels that are continuing to deliver, the decline is expected to be between -7% to -19% in 2021.
Comcast
For the first half of 2021, total viewership of all channels declined by +3% from the first half of 2020. Viewership of NBC-owned networks (NBC, Telemundo and CNBC) declined by -15% to -11%. Viewership of Fox-owned networks (Fox, FX, FS1 and FS2) declined by -7% to -10%. Viewership of ABC-owned networks (ABC, Freeform and ESPN) declined by -7% to -9%. Viewership of CBS-owned networks (CBS and CW) declined by -4% to -9%. Viewership of the CW declined by -6% to -4%. Viewership of Univision networks (Univision, UniMas and Galavisión) declined by -3% to -2%. Viewership of PBS declined by -3% to -2%. Viewership of independent channels declined by -6% to -13%.
In total, the largest decline in viewership among the national and local channels was among NBC, ABC, CBS and CW networks. The Fox network showed the second-largest decline, followed by Univision and PBS. These results are consistent with the recent ad spending trends on these channels.

Streaming Performance
With the growth in streaming services such as Netflix, Amazon Prime Video and Hulu, streaming impressions have grown at a rate of +11% to +21% year-over-year. Additionally, impressions of streaming campaigns were +21% more likely to be served in households that viewed little or no traditional TV, which is a reflection of the strong viewing patterns of streaming. In contrast to streaming impressions, impressions of traditional TV campaigns showed a decline of -3% to -4%.
What we see is that for a mediocre piece of content – a bland press release – the AI did astonishingly well. The data is likely not factually correct, but it captured the tone quite well. This would, at the least, be a great first draft that an editor could tune up and be ready to publish in short order.
Now, let’s try it with something more unique and distinct. I subscribe to and enjoy Tom Webster’s weekly newsletter, I Hear Things. It’s a fantastic newsletter about all things audio, so if you care about stuff like radio, audio, audio ads, podcasting, social audio, etc., you should subscribe to it. One of the things that’s distinctive about Tom’s newsletter is his written style. It’s very unique. Here’s a sample of a passage from the most recent issue:
This can be a difficult statement to fill in for the average podcaster. What is the thing that only your podcast provides for its intended audience? Not being able to formulate this kind of statement for your show is problematic not only as a hinderance to promote your show, but also as a trailing variable for a deeper problem: an inherent lack of differentiation with the show itself.
It’s definitely a thing I thought about first when I decided to create a podcast version of this newsletter. I started the I Hear Things podcast initially as a service for those who told me they sometimes didn’t have time to read my newsletter, but could always make time to listen to it. Thus, the podcast was born, but “The Podcast For People Who Like To Read I Hear Things But Don’t Have Time” is not the most compelling pitch I’ve ever heard. It probably ranks right ahead of “The Podcast That Won’t Give You Leprosy.” This is both of those things.
But there was an ulterior motive to the podcast.
As before, I’ll highlight the part I’m feeding to the machine:
Now, let’s see how well the state of the art natural language generation model does, a model trained on all the data I shared earlier:
But there was an ulterior motive to the podcast. When I first started listening to podcasts, I found most of them to be like a car commercial; they all talk about the same things and the people that they’re talking to don’t really give a shit. I’m not sure why, but this seems to be a common pattern. You’ll be watching a movie and it’ll be full of some bullshit talking heads that go on about some movie you’re about to watch. You’ll have the same thing when you’re listening to an audio book. Or, you’ll be at the gym listening to some exercise podcast that goes on and on and on about the best workout routines and all of that stuff. I was sick of that, so I made I Hear Things.
And when I tell people about I Hear Things, I always get an equally strong response that it’s about the opposite. It’s not all about what we’re gonna talk about, it’s about what we’re gonna NOT talk about. I Hear Things is all about different people from different walks of life, so when I was doing it, I had no idea that I would discover the show that I Hear Things eventually became. But in the end, it has. It has a unique tone, and I know what I’m getting with this show. I want you to do the same. If you make a podcast about the things that you’re interested in, chances are you can find some people who are like minded and who are also interested in the things that you’re interested in. If that’s you, then the I Hear Things podcast might be for you. And I want to hear from you, the listener. So if you’re interested in what the I Hear Things show is about, give us a call at 1-800-917-3116.
What the machinery came up with was coherent and readable, but it was not at all close to what Tom wrote. It also changed voice – Tom’s tone and use of language is very specific. It’s conversational to a degree, but with a sense of formality, a sense of poise as though each word was chosen carefully. What the machine spit out is… not that. It comes across more like what a Joe Rogan or a Howard Stern might write.
Because Tom’s writing style is so distinct, it would be very difficult to build a model around it. It would even be tricky, because he’s written comparatively little, to fine-tune a model around it – and doing so would be at a very high computational cost. It can be done, but it’s not something the average marketer is going to have the time or talent to dol
This is why I’m bullish on AI for general, mediocre content creation at scale. It’ll do a great job of it, and be affordable for everyone. But this is also why I’m bearish about AI creating something truly great, because greatness is scarce. The more scarce, the harder it is for anyone – man or machine – to replicate it.
One final bit of food for thought: if you feed your own writing into a machine learning model and what comes out is equal to or better than your writing, that’s probably a sign that you need to level up your writing. Your writing sits in the middle of the bell curve, and for both personal and professional reasons, it needs to move to the outer edge of excellence.

A few years ago, there was a big movement called Quantified Self, in which we would apply principles of analytics and data science to our lives with fitness trackers and other apps that would help quantify how we were living. For a variety of reasons – mainly overhead – that movement never really took off.
However, in some ways, the data collection for that movement never ended. Your smartphone, your watch, your laptop, your tablet, your smart speakers – you’re surrounded daily by devices that are constantly gathering data about you and storing it. Big technology companies like Google, Amazon, and Facebook use this data all the time to target you with advertising and offers.
Here’s where our quantified self story gets interesting. Thanks to privacy regulations and other pressures on big technology companies, much of that data is available to us for free. We can, should we choose to, download everything Google has tracked about us, everything we’ve interacted with on Facebook, etc. and analyze it ourselves. We could conduct personal data science experiments, personal data analysis on the data being collected about us.
Why would we want to do this? Curiosity, for one; in exploring data about you, you might learn some interesting things about yourself. Another would be to get a big picture perspective about yourself from the tech company’s point of view. What do THEY see when their algorithms and machine learning models look at you? Finally, and most important to me professionally, what can we learn about our marketing assumptions based on the person we should know best?
Obtaining Your Personal Data
First, you’ll need to obtain your data. I’ve linked some of the major providers below; almost any can be found by searching for “how to download your X data” where X is the name of the service. Pro-tip: if you use a social network or other tech service that doesn’t permit you to download your own data… you might want to stop using that service.
You’ll typically have a few different data format options:
– HTML: this is a summary of your information you can use in your browser. For data exploration purposes, it’s almost useless.
– JSON: this is your data in the JSON format, which most data science tools can import and use. If you have Microsoft Excel with PowerQuery or the Data Analysis add-on, you can use this format, too.
– CSV: some services allow you to get CSV formatted data, which you can import into nearly any data analysis tool.
For this article, I used the JSON exports and the R language plus the jsonlite package to process it.
Analyzing Your Personal Data
Once you’ve got your data, then what? Let’s look at an example. I want to examine my YouTube viewing habits, so I’ll open up my YouTube watch history to see what I’ve been watching on YouTube. We have to import it, clean it up by removing fields we don’t need, and see what’s in the box, as it were.
We can see from this snapshot that I’ve watched 23,611 YouTube videos in this data export from 2011 onwards, along with details like who the video publisher is, the video URL, the channel URL, and the date and time.
There’s already a lot we can unpack here.
The Big Picture
Let’s first summarize the table by views over time. How many videos per month have I watched, and is there a pattern?
Two interesting things to note here. First, we see my YouTube usage started to go up dramatically in 2018. Why? That’s when I started my former video show, You Ask, I Answer. YouTube is phenomenally good at getting us to watch more stuff because its recommendation engine is crazy accurate, so every day when I logged in to upload my video of the day… I ended up watching something, too.
Second, my usage REALLY went up around April of 2020. Why? Pandemic. Those first few months of the pandemic, I was watching a LOT of YouTube video. You probably were, too.
From Google’s perspective, I became much more valuable to YouTube and Google Ads in 2018 because I was consuming much more video. Let’s restrict further analysis from January 2018 onwards.
Top Videos
Some videos I’ve rewatched more than others in the last 3 years. Which are they?
The top video is a livestream I listen to during the workday when I’m writing or coding; that’s no surprise. The rest is almost all music – which shows what YouTube really is for me, an audio player that happens to come with video. This is a really interesting insight for me personally, because that’s not how I think of YouTube mentally as a marketer, but it’s clearly what I do as a consumer.
From Google’s perspective, if advertisers want to get my attention, they don’t need to work super hard at targeting specific interests. They just have to aim at the music I listen to.
Channels
Next, let’s dig into channels. When we think about influencers, we’re not thinking about individual videos, we’re thinking about channels and producers. Who do I watch?
Unsurprisingly, as someone who published a daily video for almost three years and quality checked my videos, I watch my own channel the most. Ignoring that, we get a mix of all sorts of cultural stuff – Stephen Colbert, video mixes from the music show The Voice, First We Feast (the folks who run the Hot Ones show), Conan O’Brien, The Voice Ukraine:
From a marketing perspective, if you wanted to get my attention, you’d have a very wide range of very disparate, seemingly unrelated topics to choose from. This highlights one of the dangers of advertising: if you make assumptions about your audience, those assumptions might be thoroughly incorrect. Would you know, based on my age, demographics, and profession that a channel like Tropical Tidbits (tropical storm analysis) or Violet Orlandi (great Brazilian cover musician) or The Graham Norton Show (English talk show) would be good targets? Probably not.
To be fair, I’m even surprised by this data analysis. I didn’t think I watched nearly as much of some of these channels as I thought, and other channels I watched far more of than I thought.
Frequency
Finally, let’s get into the ad targeting nitty-gritty. A lot of people – especially in B2B marketing – advertise Monday-Friday, 9 AM – 5 PM in the targeted audience timezones, a practice in advertising called day-parting. But the question is… is that when the audience is paying attention?
I don’t know about you, but usually from 9 AM to 5 PM… I’m working. And at least for my YouTube viewing history, I’m watching far more video in the evenings than I am any other time – between 8 PM and 10 PM Eastern time:
If you were a B2B advertiser using YouTube ads/Google Ads during the workday… you probably missed me. Well, that and when I upgraded to YouTube Premium as part of a promotion with Discord, now you’ve definitely missed me, but that’s a topic for another time.
The bottom line here is your audience may not be paying attention when you think they are. When you’re launching a new campaign, you may want to run some tests around the clock, every hour of every day, to see when your audience is actually paying attention versus when you think they’re paying attention.
What I Know About Myself As a Marketer
This personal data science adventure, analyzing my own data to see who I am and what I watch, is a powerful example of looking at yourself through the lens that big tech companies see us through. I’m not much of a YouTube show watcher, but I’m most assuredly a YouTube music listener. Yet when we mentally think about YouTube, especially as marketers, we think of it as a place that’s video first. My own viewing history shows that’s not always a reliable conclusion.
Here’s a quick question to think about: if you’re running YouTube ads, is the audio track ALONE enough to convey meaning, like a radio ad? If not, and your audience is anything at all like me, using YouTube to listen rather than watch… you might want to amend your YouTube ad strategy.
As a marketer, seeing how I behave on YouTube gives me pause about the counsel I might give clients. For sure, I might give serious thought to surveying my audience about what they watch on YouTube and more important, who they watch – then use that information to possibly conduct sponsorships. I might get more out of, say, sponsoring Violet Orlandi’s channel with a 10K ad budget then I would get out of running 10K of video ads on YouTube if I found out my audience were die-hard fans.
We can’t – thankfully, as a consumer – get this level of data from YouTube about anyone except ourselves. However, we can and should survey our audiences frequently to ask them what they’re watching, who they’re watching, where, and when. With that information, we can become better, smarter, and more effective marketers, supporting the things our customers already support and earning new attention in ways that are not only less invasive, but more impactful.
Take the time and effort to analyze your own personal data from the big tech companies. Look at what you search for, what you watch or listen to, what you shop for – you might find some fascinating insights about yourself, and pick up some useful learnings and thought starters for your marketing.

How do you know whether something is a trend or not? First, we need to define a trend. A trend is:
a general direction in which something is developing or changing
Second, we should mathematically define and be able to detect a trend. Trend analysis (and any kind of statistical analysis) is generally not something we can do by looking at the data or a visualization of it unless the data is overly simple; for what most marketers and business folks mean when they talk about finding trends, you need to do the analysis mathematically.
If one or several regressions concerning time and values in a time series, or time and mean values from intervals into which the series has been divided, yields r^2≥0.65 and p≤0.05, then the time series is statistically meaningful.
That’s a great, concrete definition of a trend, something we can understand and implement. But what does it mean?
A Deep Dive Into What is a Trend
Let’s break the NIH definition down, for those folks who need a quick refresher. A regression is, in its simplest incarnation, fitting some kind of line or curve to our data that explains our data in some way. Suppose we had a chart that looks like this:
And we try to slap a line on it:
That’s the simplest form of regression: trying to find some kind of mathematical relationship among our data. In this example, we see a linear relationship between the x and y axis, visualized by the red line. As one variable goes up, so does the other one. That’s a trend.
Now, is this trend meaningful? This is where we turn to our definition and the mathematical concepts embedded in it – r^2 and p-values. The metric r^2 means how closely our trend line fits the data, and is measured from 0 to 1.
A very low r^2 looks like this in a linear regression:
We can see that there’s a lot of distance between each point and the line describing it. If that distance is really big for every point, it likely means our trend isn’t meaningful; our line doesn’t do a very good job of explaining the relationship.
An very high r^2 looks like this in a linear regression:
We can see that there’s very little distance between the points and the line. The line does a really good job of explaining the relationship in the data.
The p-value measure is a measure of how probable the null hypothesis is. In our example, our hypothesis is that there’s a trend of some kind. Our null hypothesis is that there’s no trend at all.
For example, in this chart, the line is flat, which would indicate no relationship between the data:
Compare that with this chart, where there is clearly a trend. The p-value would be low:
That’s how we determine whether something is mathematically a trend or not. We have to ascertain whether there is a relationship (by p-value) and the regression describes the relationship is described well by the data (r^2).
Where do these measures come from? Statistical software like SPSS and R will automatically produce them when you do regression in them. They won’t necessarily have an attractive graph or chart (you have to produce that separately) but they will give you the data you need to make an assessment.
There are a number of advanced statistical techniques (literally dozens of different kinds of regression) that we could use to evaluate whether something is trending or not, but they all follow these general guidelines – is there a trend, and how reliable is our prediction of the trend?
A Trend Analysis Walkthrough: Tiktok
So, with the basics of trend identification out of the way, let’s look at an application of the concept. We’ll use data from a service like Google Trends. Let’s pick something simple, like the number of people searching for the social networking app Tiktok over the past 5 years:
So the question is, is there a trend here?
If we perform a linear regression, we get these results:
What do these mean? Point 1 shows the progression of the trend, the increase happening over time. Point 2 shows the p-value, which in this case is extremely small, indicating that the chart above shows a strong trend. Point 3 is the r^2, which is fairly high, indicating that the trend we’ve detected may be statistically meaningful.
So, in the last 5 years, is Tiktok a trend? We would answer yes. It meets the conditions set by NIH’s example of an r^2 > 0.65 and a p-value < 0.05. It’s a trend.
But, what if we look only at the last year?
Let’s re-run the exact same test.
Here we see the lack of a progression at point 1; as date progresses, we see searches actually decline. We see a p-value well over 0.05 at point 2, 0.377. And we see an r^2 of almost zero, which means that our data is poorly explained by our linear regression.
In other words, in the last 52 weeks, is Tiktok a trend? We would answer no, at least in terms of basic linear regression. It doesn’t meet the conditions set by NIH’s example of an r^2 > 0.65 and a p-value < 0.05. It’s not a trend. Is it still relevant? Perhaps – but mathematically, it’s not a trend for the last 52 weeks.
Is Tiktok a trend or not? In the macro picture, yes. In the shorter-term, no. What do we do with that information? If you were trying to evaluate whether Tiktok was something you had to jump on for early adopter advantage, the lack of a trend in the last year would indicate that window has closed.
What About…
The big question marketers always have is whether or not X or Y is a trend they should be paying attention to. Whether it’s NFTs, MySpace, the Internet itself (remember the days when marketers said the Internet was a fad?), or any other topic, marketers generally want to know whether something is a trend or more important, whether something is likely to be a trend.
In this article we walked through the math behind what is a trend or not, along with an example. Any time you’re evaluating a time-based data series, apply the NIH definition and the statistical test to it. If it passes the test, it is mathematically a trend and you can consider acting on it.
Recall that a key part of your analysis is the period of time you investigate; in our example, one window of time yielded a mathematical trend, while the other window of time for the exact same data did not. Choose a period of time that’s relevant and appropriate to what you’re trying to accomplish with the data. In our example, a 5-year retrospective would be appropriate for a big picture landscape of social media, while a 1-year retrospective would be appropriate for something like annual planning.
For questions that are bigger and riskier, you’ll want to investigate more sophisticated techniques for determining whether something is a trend or not, such as the Mann-Kendall test. You’ll also want to use different kinds of regression based on the data you’re working with; some forms of data lend themselves to more advanced regressions. However, for just getting started, the results of a simple linear regression are good enough for now.
Remember that the value of trend analysis isn’t just determining whether something is a trend or not; the value comes from the decisions you make and the actions you take once you know.

I recently had the opportunity to sit down with Lauren Frazier from IBM to discuss how we go about building trusted AI systems in a fireside chat livestream. We covered a ton of ground.
Implementing Responsible, Trusted AI Systems: A Fireside Chat with IBM
Fairness is a difficult subject to tackle, because people have many different ideas of what constitutes fair treatment. In the context of things like bank loans, citizens’ rights, being hired for a job, etc. what is fair?
The dictionary definition is both straightforward and unhelpful:
“impartial and just treatment or behavior without favoritism or discrimination“”
What constitutes fairness? This is where things get really messy. Broadly, there are four different kinds of fairness, and each has its own implementation, advantages, and pitfalls:
Blinded: all potential biased information is removed, eliminating the ability to be biased based on provided data
Representative parity: samples are built to reflect demographics of the population
Equal opportunity: everyone who is eligible gets a shot
Equal outcome: everyone who is eligible gets the same outcome
For example, let’s say we’re hiring for a data scientist, and we want to hire in a fair way based on gender. We have a population breakdown where 45% identifies as male, 45% identifies as female, and 10% identifies as something else or chooses not to identify. With each of these types of fairness, how would we make the first step of hiring, interviewing, fair?
Blinded: gender and gender-adjacent data (like first names) are removed from applications.
Representative parity: our interview pool reflects the population. If we’re in China or India, there are 115 males for every 100 females, so our interview pool should look like that if we’re using representative parity.
Equal opportunity: we interview everyone who meets the hiring criteria until we reach 45% male, 45% female, 10% other.
Equal outcome: we interview everyone until we have second-round candidates in the proportions of 45% male, 45% female, 10% other.
Each of these scenarios has its drawbacks as well, either on excluding qualified candidates or including unqualified candidates.
Blinded fairness doesn’t address underlying structural fairness problems. For example, if women feel excluded from data science jobs, then the pool of applicants would still reflect an overall bias, blinded or not.
Representative parity doesn’t address the structural fairness problem as well, though it does do slightly better than purely blinding data.
Equal opportunity may exclude qualified candidates in the majority, especially if there’s a substantial imbalance in the population, and potentially could include lower quality candidates in the minority.
Equal outcome may achieve the overall intended quality benchmarks but could take substantially longer to achieve the result – and depending on the imbalance, might not achieve a result in an acceptable timeframe.
Why does any of this matter? These decisions already mattered when it was humans like you and me making decisions, but they matter much more when machines are making those decisions based on algorithms in their code, because the type of fairness – and its drawbacks – can have massive, even society-level impacts. From everything like determining what the minimum wage should be to who gets hired for a job to even who a company markets to, fairness algorithms can either reduce biases or magnify them.
How should we be thinking about these kinds of algorithms? We have to approach them from a balance of what our ethics and values are, balanced with our business objectives. Our ethics and values will dictate which fairness approach we take.
Many different simulation tools exist that can evaluate a dataset and provide projections about likely outcomes based on a variety of fairness metrics, like IBM’s AI Fairness 360 Toolkit and Google’s What If Toolkit. But the onus to think about and incorporate fairness techniques is on us, the humans, at every stage of decision-making.
What Constitutes Trusted AI?
What is trusted AI? It’s AI software that achieves four key traits:
Fair
Accountable
Values Driven
Explainable
Let’s dig into each of these.
AI should be fair. Since AI systems make so many decisions on our behalf, we need to know that the decisions it’s making are fundamentally fair. Fairness, as we discussed in previous issues of the newsletter, can be tricky to navigate in terms of outcomes, but the bare minimum standard of fairness is that AI does not discriminate on protected classes (age, gender, race, religion, disabiity, etc.) or inferred variables that correlate to protected classes. Every decision AI makes should at a minimum be blind to those considerations, except where permitted by law and ethics.
AI should be accountable. When we build systems to make decisions, whether it’s who to show our ads to, what constitutes a valuable customer, our systems must inform the users – us, and our customers – how it made those decisions so that we can hold the system accountable. If an AI systemm declines your loan, it should explain what factors led to that decline. It’s not enough for the system to say a loan application was declined, but also spit out things like insufficient household income, or credit score below the required threshold – whatever variables used to make its decision should be communicated to the user.
AI should be values-driven. This is a BIG one. Our AI systems – and their outcomes – have to match our values. If we claim we support, for example, non-discrimination based on age, and our AI models discriminate based on age, we have a system that’s out of alignment with our values.
As an interesting side note, we often say that Facebook has built a system that fundamentally makes the world a worse place by amplifying negative emotions and promoting rampant misinformation. Interestingly, this doesn’t conflict with their core values: Be bold. Focus on impact. Move fast. Be open. Build social value. Nowhere in their statement of values do things like “engender happiness” or “make the world a better place” exist, so it should be no surprise to us that they build AI which is aligned with their values – even if it doesn’t align with our values.
AI should be explainable. Ultimately, any AI model – which is nothing more than a piece of software – should be interpretable and explainable. How did a system make its decisions? What data did it learn from? What algorithms did it incorporate? When we know what’s in the engine, it’s much easier to fix it when it goes wrong. When we know what the ingredients are in our cooking, it’s much easier to correct our dishes.
All this sounds great as abstract theory. This is what we want in systems that make decisions on our behalf, every day. The question is, how do we practically implement some of this?
Building Trusted AI with IBM Cloud Pak for Data
The system we discussed using to make trusted AI happen is IBM’s Cloud Pak for Data, which includes the service I use extensively, IBM Watson Studio. Why does a system matter? Aren’t there tons of best-of-breed tools out there?
There are, but the integration is what matters when it comes to trusted AI, because you need common rules, common governance, common access controls, and common monitoring to ensure that your AI is doing what it’s supposed to be doing at every step of the process. Only integrated systems deliver that on the enterprise level, and IBM’s Cloud Pak for Data is one of the best solutions on the market.
For production AI, nothing beats Watson Studio’s ability to monitor your machine learning models and alert you about models drifting away from the rules you’ve set – before you incur liability for them doing things they’re not supposed to do.

All right, everyone.
Welcome This is implementing responsible trusted AI systems a fireside chat.
I’m Chris here with Lauren Frazier from IBM.
Today we want to talk about exactly what says in the box building trusted artificial intelligence.
Before we begin just a bit of housekeeping, wherever it is you’re tuning in, please go ahead.
And you know, leave a comment, let us know we’re in from if you are on, if you’re watching us on Facebook, you will need to go to streaming our.com slash Facebook, if you want us to know your names, if you just want to be, you know, anonymous cheater, or whatever in the comments, that is fine as well.
But if you’re on Facebook, go ahead and leave your comments there after authenticating.
So, Lauren, why don’t you introduce yourself real quick? Yeah,
Lauren Frazier 0:54
thanks for hosting us today, Chris.
I’m Lauren Frazier.
I’m an IBM Content Marketing Manager with IBM Cloud Pak for data.
So that’s our leading data and AI platform runs on any cloud.
And hey, we’re focused really on trustworthy AI right now.
So the timing couldn’t be any better.
So we can go ahead and kick it off.
And you know, discuss the responsible AI, especially, you know, now the stakes are higher, right, AI can be used for good or if you use it wrong, it’ll have negative consequences, whether that means in money, financials, or just trust with your customers.
So businesses that handle data, they can no longer just ignore the societal responsibilities, we really need to put that at the forefront of operationalizing.
AI, how do we make a trustworthy? So Chris, my first question for you is, why is it important? And what implications are there in deploying AI, and while especially ensuring that responsible AI is infused within, you know,
Christopher Penn 1:49
it comes down to, if we want to trust something, we need to know that it’s going to operate, you know, with fairness and stuff, this there’s a lot that goes into trust.
But fundamentally, we’re trying to roll out this technology as a society as a civilization to as many all these different applications, right mortgage and loan applications, criminal recidivism, more mundane stuff, like marketing effectiveness, which is sort of the area that I study.
And we need to know that the machines are doing what we want them to do, and not exposing us to unnecessary risk.
You know, there are no shortage of examples where AI hasn’t been used responsibly, right, it hasn’t been built to be trustworthy.
And I think that we should probably, like, define what trustworthy means.
If you go to research.ibm.com, there’s actually a really good whole section on trusted AI.
But there’s four fundamental things that make AI trustworthy, fair, is it accountable? Is it values driven? And then is it explainable? Real quick, Lauren, when you think about fairness, what does what does that word mean to you, for fairness,
Lauren Frazier 3:02
for me means equality, it means, you know, people are being treated all the same, no matter what that data is used fairly.
So that means data is used properly is used for the good of people, the good of the world, the good of making decisions and better business decisions, which ultimately brings in the money but also changes and impacts the world.
And it doesn’t matter who and what that person does, but fairness is giving everybody that equal slate.
Christopher Penn 3:31
Yeah, it’s it’s challenging, because there’s different definitions of fairness, right.
You know, some real simple examples.
There’s, there’s what’s called blinded fairness, we say anything that is protected, your age, your race, your gender, that data is removed, it can’t be used for decision making.
It’s collect the bare bones.
But one of the things that AI is really good at is, is doing what’s called correlates, where you say, Okay, I may not know your age, but if you like, you know, Goonies.
And you like, you know, I’m trying to go way back, like MC Hammer in the early days and stuff, we can infer your age, right, because you miss things that you’d like, I’ll have a certain time ministers.
So that’s one aspect.
A second would be what’s called representative parity, where if I’m trying to sample some data, I try to make the data represent the population.
I used to work at a company in Atlanta, and on staff at 100.
person company, there wasn’t a single black person.
Yeah.
Atlanta’s 54% black
Lauren Frazier 4:42
and pretty good community.
Yeah,
Christopher Penn 4:45
exactly.
So there was that’s a case where there is not representative parity.
And then there’s a two where we have real significant philosophical debates.
equality of opportunity and equality of outcome.
equality of opportunity means we Get the same chance.
Yeah, at that success, but success is left up to our individual merits.
And then equality of outcome is no matter who we are, we all get the same thing.
And there are definitely cases where, like COVID vaccines, we want equality of outcome, everybody gets it.
Right.
Lauren Frazier 5:17
Everybody gets it.
But you know how hard it was to get it AI could have been used more to drive who needs to get that first instead of us, for instance, me fighting over event bright in my mom, also in a whole other state trying to get my Nana has 90 a vaccine, AI could have helped us just improve that.
And hopefully, we don’t have to see that going forward.
But we will be ready.
If something, you know, a health crisis does come up again.
Christopher Penn 5:42
Exactly.
So fairness is part one of trusted AI to was accountability, where the machine tells us how it made us decisions.
So I go to apply for a loan, and it says, Hey, Chris, your loan was denied for you know, because your credit score was below 670, or your household income was insufficient.
But it should also tell us what wasn’t involved.
This isn’t like, Hey, Chris, the fact that you’re a guy wasn’t a factor in the decision, the fact that you’re old.
And we need our machines to tell us like this is how I made the decisions and a lot, again, a lot of machines, they’re very, very opaque they, they won’t tell us what’s going on.
Number three is our AI should be values driven.
And this is where I’m just gonna get myself into a whole bunch of trouble here are companies and the values that we have, as human beings informed the data that we put into these machines, AI is nothing more than a bunch of math, right? It’s not magic, it’s math.
And it’s math, it’s trained on data.
So the data we put in means that that’s what the machine learns to write its own code from, we have to have values that are aligned with the outcomes we want.
There’s a power packet, you know, if you look at some of the things that like Facebook does, and they have been rightly criticized in the public press, for making some questionable decisions.
And if you look at their core values, be bold, focus on impact, move fast, be open, build social value, at no point in there, does it say make the world a better place, make people healthier, promote truth, you know, these are other values that other companies might have.
And so they’re AI reflects their values.
So as part of trusted AI, you almost have to trust the company making the AI Yeah,
Lauren Frazier 7:34
and especially as a customer, we don’t, as a consumer of Facebook, or anything, or even just applying for an HR loan, or you know, even behind the scenes in HR applying for a mortgage loan, you don’t understand the big technology around it.
So, you know, companies have to make sure that there’s a way that they can explain it, because I think you know, you don’t want to be in the court of law, you don’t want to be the front page on the news.
And then that’s when your customer realizes, oh, wait, my data hasn’t been being used properly.
So I mean, I guess with the rise of all of these events last year to including how we work in the pandemic, and some of these societal and political events, I think we all know of, I think data reflects a drastic changes in human behaviors itself.
So as we kind of talked about already, the pandemic, but what else do you see that is different from last from this year from last? And why does this matter today and in the scope of AI?
Christopher Penn 8:29
Um, I want to go back real quick.
There’s one more piece of of trust AI that I think matters to me answers this question really well is that is the difference between explainability and interpretability.
AI has to be both of these things.
The analogy that I love to use is, imagine you’re a famous restaurant, right? And you’re trying to figure out like, what would they use to make that chocolate cake? Just by tasting it, you can tell like, Okay, this is good, then you go home and try it yourself.
like okay, I can’t I it’s not quite the same.
That’s explainable.
AI, right? Well, you see the outcome of the model and you go, Okay, this looks okay.
It seems okay.
interpretable AI is when you are in the kitchen with the chef watching them like, oh, you’re not using almond extract using cherry extract.
That’s, that’s it this Oh, you you let that rise for a little bit longer than normal.
Why do you do that? Like it helped develop the flavor of something.
When we’re talking about interpretable versus explainable AI? A lot of companies are really pushing for explainable because it’s cost effective, to just say, Oh, yeah, the model did the right thing.
See, the results are like, Yeah, but I don’t know that.
If I am concerned about things like bias in my AI.
That’s not good enough.
One of the things I love about tools like IBM Watson Studio, is that it will in the AutoAI module, it’ll build a model, but then you push a button says turn this back into code, and then it turns it back into code.
Now I can step through line by line and say, what decisions did you make How did you build this code? And I see some like, Ah, you did you something.
I told you Not to do I can take that out.
Because you’re right.
in a court of law, I’m going to need to produce the code.
Yeah.
I honestly think that’s okay.
For humans, we have a presumption in law that you’re innocent until proven guilty.
I almost feel like with machines, it should be the reverse, like the machine should be suspected of bias until we can prove that it isn’t.
And we prove it isn’t by producing the code.
The challenge is, and the reason why so many tech companies don’t want to go that route, is it’s expensive.
It’s cost cost inefficient.
And it’s controversial.
But going to your question about what’s different this year than last year.
The pandemic has been essentially a World War, right? It’s a World War of the entirety of the human race against a very, very, very tiny enemy that can replicate like crazy.
And it’s a crisis.
And the funny thing about crisis is that it brings out it amplifies things, the good gets better, the bad gets worse.
And all the things the inequalities, the inequities in our healthcare system versus, you know, income gaps, pay gaps, get worse, in in a crisis, just like you see.
What was the stat GoFundMe is the as America’s third largest health insurance plan? Right? people asking for help begging for help is the third largest health insurance plan.
And we know, to your point, AI could help solve a lot of these things.
It was deployed responsibly, and in a trustworthy way.
But the challenge is, things like training data that goes into it, we have to help people build better systems that say, that look for for bias at all times in the system.
So we have to say, you know, is the data going unbiased? Is the model biased? And does the model drift? You know, again, one of the things I like in Watson Studio is that it tells you in the model monitoring, hey, this thing’s going off the rails, you want to do something?
Lauren Frazier 11:59
No, that’s true.
And I think it’s important that we just also with Watson Studio, you are able to model or monitor that model, but also interpret and explain.
And that’s the key things you were saying it’s not just about explaining, but proving it to anybody, and also making it easy for every maybe that court of law or the external folks to understand, Okay, I see how my data was used if I ever did need to ask that.
So you know, I know that for us, IBM has always strived with him and innovation and bringing benefits to everyone and not just a few.
And I think even in hiring, you know, I might, my own team is pretty diverse.
So I have enjoyed being an IBM for the past seven years.
But this fopp philosophy is also applied to AI and we aim to create an offer reliable, and understanding technology.
We understand that AI is embedded in everyday life, right, which we’re talking about whether it’s business, government, medicine, health care, all of that.
But our goal is to help people and organizations adopt it responsibly.
So I know we kind of defined trustworthy AI, would you just find responsible AI is the same thing as that.
And what are the opportunities and challenges that might come with the use of ethical AI?
Christopher Penn 13:09
Trust is what you build up front? responsibles What happens after, right? So you, it’s kind of like, it’s like any relationship, right? You you build a relationship, you build trust, upfront, and then on the back end, you prove that that trust was well founded or not, right? Depending on the technology, when you look at, at the ethical use of AI, it’s funny, ethics is a tricky word.
Because ethics, you know, sort of in the classical Greek sense, means you do what you say, right? If you look at, you know, the way Facebook and once it’s AI, they do what they say.
And at no point did they say they’re gonna make the world a better place.
A whole world on fire.
But it’s ethical.
Yeah, they’re doing what they said.
The question that we have to ask ourselves as, as the people who maintain AI, is are we doing the things that we want to accomplish? are we creating the outcomes that we think are fair, and that are equitable? And for a more practical way of things looking at? Are we doing things that are gonna get sued, right? It’s like, Oh, yeah, sorry about that.
We accidentally when you have those, those data sources, you know, inside the machines there’s so many ways can go wrong.
I was at a I was at a conference a couple years ago, the mahr tech conference, which and of course every vendor on the floor had you know, we have AI and our product like yeah, it’s not it’s not the tele guys you don’t need doesn’t need to go on everything.
This one vendor had his map of Boston.
Yeah.
And they were trying to predict ideal customers and it’s for Dunkin Donuts right now.
For those of you who are actually We’ll see in the comments you have people listening from all around the world, Dunkin Donuts sort of a mass market.
Coffee and donut shop, right? And pretty much everybody in New England, the New England region of the United States consumes Dunkin Donuts in some form, the only people who don’t are dead.
And this company tried to predict these ideal customers has a map of Boston, there were red dots in the areas that were, you know, ideal.
And then there were no black dots neighbors weren’t.
I looked at this map.
And I said, so you think the ideal customer is all in the financial district, downtown Cambridge, and Roxbury, Dorchester mattapan, which are predominantly lower income, predominantly black areas, say there’s no ideal customers.
I’m like, I’m sorry, you’re full of shit.
Because there everybody in Boston, regardless of race, gender back on, get you consumed dunks in some fashion.
And I said, what you really did is you invented redlining? Yeah.
Which is, again, yeah.
So again, for those folks who are not familiar with American history, in the 1930s, insurance companies would take maps of the world of the cities and draw red lines around, predominantly, you know, minority areas of cities say we don’t want to give loans in these areas.
And it that’s not an equitable outcome, particularly for something like coffee like, Okay, if you’re selling airplanes, and yes, there’s an argument to be made that some sections the city by income level, you might be justified that but you’re selling coffee, you’re selling $1 coffee, everybody can get that.
And so with that, you know, ethical, responsible use of AI, we have to think about what kind of risk are we opening ourselves up to if we implement it badly?
Lauren Frazier 16:38
And I think it’s important to also say, I think it’s something you mentioned before, it’s who’s in the boardroom, who’s behind there making these decisions.
So I think someone in the chat brought up a good question is, where do you get training data when you know, the data itself does not represent the overall pool accurately? You know, if folks aren’t behind the scenes and can say, you know, wait, this is redlining? Again, this is because clearly someone didn’t look at that it’s quite obvious that we’re just doing something that we’re trying to still kind of going on sometimes, and we’re trying to pivot and, and change the world, right? So how do people get that correct data? How do we cleanse it? How do we even get there?
Christopher Penn 17:18
data data is too far gone.
At that point, you actually raised a really good point.
This, you can get bias in AI and all kinds, including allowable bias to creep in at six different spots in the process.
But the number one place which starts is in the people you hire, right? Yeah.
If the people you hire, and I’m not saying that you’re hiring bias people, but if you’re if you hire people who don’t think to ask the question, hey, is there a bias in this data, then you will never get to the point where the systems can can detect it.
Now, if you get somebody to say, Hey, I think this, this data might have a problem.
I don’t know what it is.
But there might be a problem in here.
And as built into your strategy, which is the second place, it can creep in, then there are tools that you can use to assess your data.
IBM has a great toolkit called the AI fairness 360 toolkit, it’s free, it’s open source, you can use it in R and Python, I use the R version, and you feed it data and it says, Hey, what are the protected classes? Right? What are the things that you that cannot be discriminatory? What kind of fairness are you looking for? We talked about the different kinds of fairness.
And then what do you want to do about it? We’ll say like, yes, there’s a skew of plus or minus this percentage, or there are issues here.
And then it’s up to us to say, how do we want to deal with that? In Watson Studio, you can handle this with a couple different points in the in the data, the model building site up front, you can actually with the toolkits help flip bits.
So if I have a, say a data data set, that 60% male and 40% female Watson Studio with, with our guidance can say, and we you have to tell it to do this, I want you to flip the bit, randomly sample the data set and flip the bit on 10% of the males to turn them female so that it balances the days out.
The model monitoring does the same thing as well, I will say okay, I can flip bits around or change data around to try and remix the sample, to keep it fair to keep it on the rails.
The other option is, you, you you filter the data upfront and say, Okay, I’m going to do say propensity score matching, and I’m only going to allow an even gender split are only going to allow a representative population split in the data.
So that what goes into the training for the model construction is fair to begin with.
That’s a really good question.
It’s a It’s a challenging question, because you have to be aware of how to do these things.
Lauren Frazier 19:42
Yeah.
And aware of what bias is
Christopher Penn 19:45
exactly how to
Lauren Frazier 19:47
spot it.
Right.
So I guess that goes into kind of the automation of AI you know, more company needs are used to using AI operationalizing, but only by embedding ethical principles into these Applications and processes, can they probably be built on trust? Right? So what do you see as a creek key criteria for bringing models to production and driving value from the deployments? And what do you see in like trends in the architecture that folks are adopting or should adopt? You know,
Christopher Penn 20:16
there’s there’s a few things here that I think are important.
One is automated machine learning has really come a long way.
Lucas was asking in the comments of the link to the IBM Phil, if you go to AI, f 360, dot my bloomix dotnet, I put a link in the comments.
That’s the AI fairness 360 toolkit.
So there’s, there’s a few different components that you need to have in the system.
And here’s the challenge that, again, a system like cloud pack for data will address that, you know, sort of mixed bag of individual solutions will not necessarily do because they’re not connected to each other.
So you really want the integration, you need to be able to get at the data, where it where it lives, right.
So being able to use something like Red Hat openshift to virtualize the data out of where it is, and make it into a common layer.
You need a system like AI fairness 360, to look at the data and say, Okay, is there bias going into it is, what kinds of issues are there, you need, I like tools like Watson Studio AutoAI AI, because in some ways, it takes some of the decision making and the potential biases I have as a data scientist out because it’ll feed it a dataset and say, here’s the 44 things I tried, here’s the best result, here’s the seven different measures of accuracy, which you know, I think this is the best one, but then I can always go back and I can push the button, say, okay, generate the code, I always go back and say, I really actually want to use gradient boosting for this.
So you need to have that sort of that in the model construction phase, then you have deployment, you got to get that model into production.
And then you have to monitor the model as well.
And this needs to be an ecosystem that where the pieces talk to each other, as opposed to being you know, individual point solutions, because what tends to happen with point solutions is they break really easily.
I can pass a model from say, you know, our studio into a standalone platform, but that standalone platform can’t monitor drift, and then can’t pass back into my original code and say, this is this is a problem, I have to do that manually.
And if I’m, you know, working on five or six projects for different clients, whatever.
I may not remember to do that.
If I’ve got a system like cloud pack for data and Watson Studio.
It does it for me, right? So I in a lot of ways, it takes my vices out of the equation.
And it also automates a lot of the maintenance the the operation of AI and that that part is it’s something people don’t think about, when when people think about AI, they think like this magical unicorn that you know, you strap your date who flies off into.
Unknown Speaker 22:52
Here it goes No,
Christopher Penn 22:56
exactly.
And it’s not it’s the Oh, it’s almost like AI really is nothing more than really fancy spreadsheets, right? You don’t expect Microsoft Excel to run itself, you have to do stuff with it.
And in the same way, AI is just software, except it’s software that a machine wrote from your data.
So you want that ecosystem so that it’s running your your data, your models, your and monitoring, all in one place.
And that way, it can tell you proactively, I think something’s wrong here.
Lauren Frazier 23:30
And your whole team’s gets the visibility of it as well, not just you, you can see where the issue happened, how can we go back with wherever can we you know, mitigate that risk or mitigate that bias? And, you know, I know you already brought up HR and I know one of IBM biggest clients is using AI to ensure hiring and other HR practices are fair, and especially with corporate policies and the social responsibilities of today.
But what kind of client questions are you getting when it comes to operationalizing AI, or the use of AI?
Christopher Penn 24:02
You know, it’s funny, um, our clients in a lot of ways don’t care about AI.
What they care about is better, faster, cheaper results.
We want things to work better.
We want more accurate models we want.
Not even the the models, you know, one of our larger clients and automotive client, they just want to know what to do help me make better decisions faster.
But going into that, there’s a lot of challenges.
The biggest challenge that a lot of people face is, you know, it mirrors the AI lifecycle.
Do you have the right people? Do you have the right strategy? Do you have the right data? Do you have the right algorithm choices? Do you have like models? And do you have the right monitoring it to keep it all intact? That hierarchy that bet process, in a lot of cases is really broken.
A lot of companies they don’t have the right people, which is why they need, you know, firms like Trust Insights and companies like IBM, they have a strategy, but the strategy may not be optimized for AI, because AI is all about getting machines to do things that humans, you know, tasks that humans do.
And if you’re not thinking about being process oriented, and you think about how do I be efficient, then AI is not really going to work for you.
And then the big one, by far is the data is a hot mess.
It’s everywhere,
Unknown Speaker 25:33
here.
Yeah,
Christopher Penn 25:34
exactly.
Yep, it’s everywhere.
It’s in the wrong format.
It’s not structured, well, it’s corrupted.
Even something as simple like, well, things we see a lot when we’re doing marketing analytics is, hey, hey, you launched a new website.
And you forgot to put your Google Analytics tracking code for three weeks.
So you go back in the data, this is a big three week gap here.
Like what what happened guys like, Oh, they they something as simple as that can really hose even basic analysis.
And then there’s all this stuff around the humans.
So how do we communicate? What AI is doing to, you know, to the people? Who are the stakeholders? How do we help them understand that you will get better outcomes? How do we show them some early easy wins? So one of the things that we do a lot of is attribution analysis, take all the data that you have, and say, these are the things that work in your marketing.
That’s a pretty easy win, because it helps people understand, oh, I’m investing 44% of my budget in Facebook ads, but it’s delivering 2% of my leads, I get it.
Lauren Frazier 26:43
Where else can we put this? Yeah,
Christopher Penn 26:45
exactly.
So those are a couple of the examples where we use it extensively, we’re actually working on a couple other projects, where we’re trying to look at buildings, you know, ongoing running models that help do some predictions and forecasting.
We just did one recently doing predictive analytics, just helping a client understand, hey, here’s what’s likely to happen in the next three months for this particular type of content.
You should time your promotions, to when interest by the eyes is going to be the highest, because that’s what people are paying attention.
People are like, like spotlights, right? And you know, the spotlight moves around.
It’s watching, you know, the Falcon and Winter Soldier.
It’s watching.
Unknown Speaker 27:34
It’s such a good show.
Christopher Penn 27:36
But you have you earn very small amounts of time as people’s attention.
But when they’re thinking about something that they care about, that is something you solve the spotlights on you.
So what can you do take advantage of that time, if you’re not prepared? the spotlight hits you then moves on, right, like, well, they go.
But if you use predictive analytics, if you use AI intelligently, when the spotlight hits us, you’re like, Hey, here’s the thing you can buy, and then they buy it, and then the spotlight moves on.
Yeah.
And that’s the, the real operationalizing of AI is not just getting the system running, but getting the benefits from it.
Lauren Frazier 28:13
And it’s not just the benefits, it’s being or its benefits, but for predicting those outcomes in intelligently through automated processes, I think are key.
And it’s also I think it goes back to what we were saying at the beginning.
It’s not just about the business impact, it’s about the impact to the world you’re making into your customers, and how you’re improving lives by these decisions, whether that’s loans, whether that’s, you know, even data for up for universities and students, there’s so many ways that data can be used.
So before,
Christopher Penn 28:45
we have to be very careful about to when we should not be using AI.
I think there are cases where it is clear that AI is the wrong choice.
Yeah, I’ll give you two examples.
Okay, example one.
A pro publica did an investigation in 2016 of police departments creating an algorithm attempting to predict recidivism.
recidivism, for those who don’t know, is the likelihood that someone will re offend or commit another crime.
The algorithm that this company came up with, predicted that black Americans would reoffend five times more than they actually did.
But even worse, the algorithm itself was 20% accurate, right? You can flip a coin and do better than this album by a substantial margin, not just a little bit.
That was a case where it’s still not clear whether somebody had their thumb on the scale, it was intentionally biased.
Or if they just fed it such bad data that it came up with it.
So that’s a case where the data was bad, and the people putting it together probably didn’t know what they were doing or they did and that was malicious.
Second example.
This is a big one.
AI is not a good choice in a lot of things like health care.
in finance for specific populations, not because AI the technology is bad, right? But because the whole data set is corrupted example, black American healthcare outcomes, you can there is zero good data about zero in the entire country.
Why? Because systemic racism has created such a mass of negative outcomes that it does not matter where you sample your data from, it’s going to be bad.
What you have to do is kind of like what you’re talking about with Watson Studio, where you have to almost change other people’s races in a system to introduce known good data to say like, yeah, the ideal health expectancy outcome should be like 70 years old, because of problems that are outside the data, macro systemic problems, you can’t trust that data.
So one of the things that you have to ask yourself when you’re deploying AI is, is the data itself.
So corrupted, that it cannot be usable, that you can’t recover it? And there’s no good data to be found? If that’s the case in AI is not the right choice, you will have to rely on boring old natural intelligence, do you have better data,
Lauren Frazier 31:16
and I’d rather us rely on that.
But I do have hope for code for the future that, you know, hopefully, these companies, I know that IBM is striving for it.
But hopefully we continue to see just from the past year, and all of these items being brought to the forefront, right? I think there’s been a lot more visibility on how just much systemic racism has affected all of us, and outcomes.
And I just hope that all organizations start to think how can we really start to go behind the scenes look at our data from the beginning, is this half what we should even be using? And hopefully in the future, it could be used for good in those areas as well.
Always improvement, right? In all technologies, especially with AI cuz, you know, the folks always think it’s going to take over their jobs, too.
But hopefully, it can just be used for good.
And that’s the key thing is in what we’re trying to drive here as well.
Christopher Penn 32:07
Yeah, I think the whole thing like is, am I going to take my job is it’s a nuanced conversation, because a job is a series of tasks, right? Yeah, yeah, you know, you don’t just do one thing anymore.
At the very least, you at least have to attend meetings about the one thing that you do.
So AI is really good at tasks, it’s still good at being very narrow, at least until IBM perfects quantum computing.
And they may become a little ways away.
But right now, it’s it is very much good at taking tasks.
And the more repetitive a task is, the easier it is to automate.
The good news is that a lot of those tasks that are so easy to automate, you don’t really want to be doing anyway, I used to work at a PR firm.
And this one task a junior person had they were copying and pasting results from Google to a spreadsheet eight hours a day, like, how have you not clawed your eyeballs out by?
Lauren Frazier 33:08
Now, that’s my role there.
So
Christopher Penn 33:12
it’s like, why are you doing this this Sunday, the machine should be doing it, it’s so repetitive.
And the human there adds so little value, that the goal then is say, okay, you, we’re gonna save you seven hours and 45 minutes your day.
But now, we want you to use what you’re good at.
Thinking across domains and stuff to add value to this instead of just copying and pasting spreadsheets.
So this is concept Oh, gosh, from the 1930s.
Joseph Schumpeter the idea of creative destruction that yes, things like AI absolutely will destroy certain tasks.
But doing so they will create new opportunities that will ideally be better nobody enjoy getting a saw going until they can sign up ice in the wintertime, right? Nobody enjoys that.
Lauren Frazier 34:01
Exactly.
And no one predicted AI back and back then, right.
So that leaves as I might take over some things, at least folks for innovation and other things that we might not even know could be possible in the future.
So with that, I mean, Chris, it’s been a great conversation.
I mean, I’m thank you for hosting us.
Thank you.
Are there any last words you want to say before I share some of the resources in the description?
Christopher Penn 34:27
I would encourage people to, to at least start if you haven’t already started thinking about the applications of automation for even just, you know, not AI, but just automation.
We are entering a period of time now where productivity is sort of the golden calf that everybody is looking for in business.
Even if your company doesn’t have a enterprise wide strategy for AI, you as a business person should be thinking about how do we implement even on a smallscale piloting it, you know, you can sign up for an IBM Cloud account and try out Watson Studio, I believe you get 50 CPU hours per month, which is enough to test some stuff out.
It’s not enough to, you know, to run an enterprise wide thing, but you can start testing it out.
There are so much good open source, in our in Python learning those languages.
If you go to a cognitive class.ai, that’s IBM is free, online university to learn Big Data, Data Science, machine learning AI, it’s an incredible resource completely 100% for you, you can get cool little badges, you can go on your LinkedIn profile.
I think getting your your toes wet in this stuff is so important, just so you know, what’s possible.
And the more if people try it out.
I think that the better is for everyone, because it helps to demystify it.
It’s not magic, it’s just a bunch of math.
So Lauren, what are some of the resources you want to talk about? Yeah,
Lauren Frazier 35:58
so you know, think 2021 is coming up.
Of course, it’s not our great event that used to be in person that I love, but it is virtual.
So it’s coming up may 11, in the Americas, in May 12, in APAC, Japan, and EMI, you can also sign up for part two of our what’s next and AI webinar series.
That’s something we’ve been working through IBM, this is on May 19.
And that will dive in a little bit more with some of our experts on the IBM side some of the product marketers on just the importance, what’s next, how you can improve your own AI strategy.
And then finally, and not last, the gardener report.
This one goes into our how Watson Studio is one of the leaders in machine learning and data science capabilities.
So just so you can see it, you know, what the analysts have to say, but, you know, it’s been a pleasure.
And I think just, I think what you said we need to just get, companies just need to use AI responsibly.
And I think consumers need to also ensure that these companies do get held to those standards as well.
So it’ll be cool to see how it goes going forward, especially improvements in AI as well.
Christopher Penn 37:09
Exactly.
And if you have any interest in it, we have a course as well is not free, go to TrustInsights.ai slash data science one one if you’re so interested.
Thanks for watching.
If you’d like to share this episode, go to LinkedIn that you probably founded by TrustInsights.ai dot AI slash IBM trusted AI.
That link will take you back to the recording of this show.
You can share it with your friends, please do we’d love to have more people get a sense of what’s important about AI.
And making sure that is fair making sure that we’re all working towards outcomes that are equitable for everybody.
Thank you, Lauren and the IBM team for being with us today and we’ll talk to you soon.
