Learning Data Science Techniques With IBM Watson Studio Modeler
When it comes to learning data science, one of the challenges we face is just how seemingly daunting the field is to learn. There are so many techniques, tactics, and strategies that it’s difficult to know where to start.

Learning something new always begins with an understanding of the basics. From martial arts to dance to data science, the basics form the underpinnings of everything that comes after. We can’t do a black belt technique with proficiency if we don’t have all the time, experience, and knowledge that comes from the belts before black belt.

With data science, the same thing is true. We have to learn the basics, the techniques, first. So how do we do that?

The Rumsfeld Matrix

Our first exploration has to be cataloging our knowledge. What do we know? For this, I use the Rumsfeld Matrix, coined by former Secretary of Defense Donald Rumsfeld. Rumsfeld opined in a press conference years ago that “Reports that say that something hasn’t happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.”

If we extrapolate this snippet of speech to a 2×2 matrix, we arrive at:

What are these?
- Known knowns. Things we know that we know.
- Known unknowns. Things we know that we don’t know.
- Unknown knowns. Things we don’t know that we know, aka things we’ve forgotten.
- Unknown unknowns. Things we don’t know that we don’t know.
What does this have to do with data science techniques? When we look at the entirety of data science, chances are our knowledge falls into one of these four categories.

For example, we know that we know linear regression.

We may know that we know logistic regression, but we also might have learned that in college many years ago and forgotten it, which would put it in the category of unknown knowns.

We know we don’t know how to do, say, GLM modeling, which would be in the category of known unknowns.

And there are a whole slew of techniques we may never have heard of. We don’t know that we don’t know them, because we’re unaware of teir very existence.

When it comes to learning data science, the categories we need to conquer quickly, in terms of cataloging, are the unknown knowns and unknown unknowns. Without understanding these two buckets, we might think we’ve got the hang of data science, but our skills are limited by what we don’t know we don’t know.

So, how would we come to know what we don’t know?

IBM Watson Studio Modeler

This is where IBM Watson Studio Modeler comes in handy. When we first log into Watson Studio and set up a new Modeler environment (which is functionally almost identical to SPSS Modeler, for those who know that particular piece of software), we’re presented with a deceptively simple menu of tools:

Boy, that sure looks easy, doesn’t it? This data science thing is going to be a cinch.

Until we start to expand the menus. Here’s what all the menus look like, opened up:

Woof. That’s a lot of buttons.

But now, do you see the value of this tool? It’s not just an environment for working in data science. It’s also a map of data science techniques, the most common techniques, all laid out neatly in order of operations:
- Data import
- Record operations (rows)
- Field operations (columns)
- Modeling
- Text analytics
- Graphs and visualizations
- Outputs
- Data export
That’s a very handy little data science lifecycle right there. And each menu has a plethora of techniques we could bring to bear on any given data science problem.

Guess what this massive set of menus is? Yep – it’s the map you need to eliminate your unknown unknowns. When you look at this list, how many are techniques you’ve never even heard of, or have no idea what they mean? I remember the first time I logged into the interface and saw a widget for CHAID – and had no idea what that stood for (chi-square automatic interaction detection).

When you have a catalog like this, neatly laid out, it becomes trivial to solve the unknown unknowns. You’ve changed them all into things you know you don’t know. You’re aware of their existence, and you’re now able to build a plan for learning what you don’t know. Your plan might be as simple as Googling each of the techniques, then exploring and playing with the widgets in IBM Watson Studio Modeler, since it’s a no-code environment that allows you to try things out fairly quickly.

I usually go with a four-part analysis of techniques I don’t know:
- What is this technique?
- Why would you use it?
- When wouldn’t you use it?
- How is it used?
For example, the CHAID technique was something I was unfamiliar with the first time I logged into Watson Studio years ago.

What is it? It’s a decision tree algorithm used to determine if two sets of categorical variables are substantially different than each other with regard to an outcome.

Why would you use it? If you have two different groups of people – say, people who saw a billboard and people who didn’t (and whether they bought something) – and you have characteristics of each that are non-numeric, such as gender or ZIP code, you could use CHAID to see whether or not the billboard had an impact, or whether other variables explain that they bought something or didn’t.

When wouldn’t you use it? CHAID builds a classification decision tree, but if a good chunk of your data is numeric instead, you’d probably want to use a different technique like CART or other regression-based techniques.

How is it used? This is where the IBM Watson Studio interface comes in handy. Because it’s a no-code, drag-and-drop interface, you just plop the CHAID widget into your workflow and you’re off to the races.

Going through this catalog of techniques will take time – weeks, easily, if not months. But that’s all right, because we are less concerned about being blindsided by the unknown unknowns. We’ve got them fairly well fleshed out now, thanks to IBM Watson Studio Modeler’s interface and catalog.

Apply Everywhere

This learning technique doesn’t just apply to IBM Watson Studio Modeler. Every piece of commercial software that’s good at what it does has the same potential, from Google Analytics to your CRM to even your word processor. What do all the features do? How applicable are they to your business, your industry? What do you know? What don’t you know?

Apply it to every piece of software you use, and you’ll extract maximum value from your tools.

You Ask, I Answer: Third Party Schedulers and Social Content Performance?
Iain asks, “Fact or fiction. Using third party schedulers for social media posts get a kick shins as they haven’t come from the native platform tools?”

Some testing has been done on this front, but none of the tests, from what I’ve read, have been done as rigorously as they should have been. Watch the video for an explanation of how to run the test for yourself.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Ian asks factor fiction using third party schedulers for social media posts, get a kick, kick in the shins as they haven’t come from the native platform tools.

This is a good question, because it highlights some of the issues that we have in marketing with analytics and statistics.

Specifically, some companies have done some testing on this Agorapulse has done some testing buffer has done some testing a few other social media posting tools have done some testing.

And obviously, one of the challenges there.

Well, there’s several challenges.

One is there’s an inherent conflict of interest if a third party company is testing to see if third party companies to penalize but that’s not reason enough to disqualify their efforts.

Because as long as it’s done in a statistically valid way, and methodologies are disclosed, and data is made available, then it’s totally fine, right? It’s the same with any kind of academic research, you disclose your funding, you disclose your conflicts of interest, if any, so that people know that the study may or may not be as neutral as it could be.

Here’s the issue with the testing that’s been done.

It’s not that it’s been by third parties, it’s that it’s not been done in a statistically rigorous way, not rigorous enough.

And the prot, the reason for this is that a lot of the data that’s out there is it’s not well structured.

So there’s two ways that you can statistically test for something like this one is to run true A B tests where you’re running the same content, well, one from one tool, one from whatever the control is, and it has to be the same content, or has to be very similar to the content so that a post that contains cats, people hit like cats, does well.

And it shouldn’t matter which method you’ve posted by.

So you have to post one with cats in your treatment group and one with cats in your control group.

That tends not to be the case when a lot of testing goes on.

And understandably so because if you’re doing that, you’re essentially double posting your content.

And it gets tricky, it gets tricky to manage that.

The second methodology that you can use is a stats technique called propensity score matching, where you take a whole bunch of data, and you group it, you cluster it and then you try to find data that is similar in each of the groups is kind of like building a, an A B test retro actively.

The challenge there is you need a lot of data, you need a thousands of data points so that you can match control groups create essentially a control group, a control group and a treatment group of similarly performing content, so that you can see if the variant is because of the treatment or not, in this case, using a third party tool.

So how would you go about doing this? Well, again, if you’re going the AV route, you create a bunch of social content, half of it, you basically duplicate it, you make a copy of everything, right.

And then you put one copy in your native platform and one copy in your Scheduler.

And after a while you run the numbers and you see which content perform better.

accepting the fact that you’re going to have double posted content.

And second method is using again, the data that you get out of your systems, you will need to tag if the social platforms in their analytics don’t give it to you, you’ll need to tag which was third party scheduler, and which was native.

And then run a propensity score match.

So let’s take a look at what this looks like here.

So this is Twitter.

Twitter, very kindly provides weather a post was well what tool a post was from, which is super, super handy.

And so if I look in my data frame here, let’s go ahead and take a look at our sources.

We have 18 different possible sources.

We have a whole bunch of individuals and then we have the Twitter family official clients and then some more individuals there.

So what I’ve done is I’ve extracted the last 3200 tweets from my account, removing retweets, because retweets.

We’re trying to test stuff that is native and then assigning if it was used, if Twitter the native platform was the source Want to go with in this case I’m going to make that the treatment doesn’t really matter is just assign the groups.

And then if it was a third party tool, make it a zero.

No, it makes more sense to logically do this, let’s, let’s back this up.

So treatment is going to be using the third party tool.

Let’s go ahead and run our matching test.

Okay, and we have as a result, the treated group meaning a third party tool, on measures of favorites, retweets and engagement, when we look at the main difference, third party content in for my account on Twitter does slightly better than the stuff from the native platform.

Now, again, this is really important.

This is my account.

So you can’t generalize this to anybody else, you should do this on your own account.

And this is for Twitter only.

So you’d want to perform similar tests, with similar data on the social platforms, you care about Instagram, YouTube, Facebook, whatever.

But this is the methodology for how you do this, you can either retro actively do it with a propensity score match, or you can do a true AB test.

Let’s take a look at one more let’s do I know it’s in the data set.

So let’s test this.

Oh, and did not work because I need to switch this to nearest? There we go.

So in this case for this account, similar the treatment slightly better.

So is there a difference in third party tools? Yes.

And actually, in this case, a couple of tests here, we’ve seen that it’s a slight improvement.

Should you generalize this to your social media strategy? No, no, I would test this with your own data, make sure that this idea applies to you specifically, because that’s what you care about, you don’t really care about my account, you care about your account.

So you’d want to to run this similar type of testing for you.

That said, based on the less statistically rigorous tests we’ve seen, based on doing something with a bit more rigor, so far, haven’t seen any strong evidence that third party tools cause harm, right, if anything, scheduled content, at least in my tests, performs slightly better.

So does that mean that you should change your strategy now? run the test for yourself first, get the answer for yourself first, and then build your strategy on that.

And if you don’t have the capacity to do this, then I would say frankly, it doesn’t hurt to use third party tools so far.

Again, the various tests have been out there kind of proven to one degree or another, there’s not substantial harm.

There’s certainly nothing that makes you go Oh, wow, that was That’s terrible.

Like, let’s let’s stop using these immediately.

It’s not the case.

And again, you have to test this for each platform you’re on because each platform has different algorithms.

You Ask, I Answer: Adopting Data-Driven Marketing Strategy?
Kait asks, “How do you suggest to go about to creating a data-driven strategy standard and breaking the “because we’ve always done it this way” mentality?”

Strategy is always a sale. Every sale has to answer the question, “What’s in it for me?” for the buyer. Not what’s best for the company, for the organization, for the big picture – what does that person get out of it? There’s a reason we call such efforts obtaining buy-in – people need to be convinced to buy.

The greatest challenge is when people don’t understand the value of data or the decisions you plan to make from it. That comes from past efforts where you collected data but didn’t do anything with it, and thus had no results to show for it. Becoming data-driven means making decisions with data, and as with everything, if you can show early, easy wins, you’ll build momentum for your strategy.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Kate asks, How do you suggest to go about creating a data driven strategy standard and breaking the, because we’ve always done it this way mentality? So the the mentality of we’ve always done it this way, is one of comfort and security of predictability.

We’ve always done it this way.

means that, yes, you’ll always get what you’ve always gotten.

But if things have been good, there, it’s difficult to sell that change.

The greatest challenge to data driven strategy is that people do not understand the data, or the value of the data, and thus, don’t see a reason to change the decision making process.

And it’s understandable why people feel that way.

But a lot of the time when you have people who are not skilled at analytics, working with data, you get a lot of what Avinash Kaushik tolle calls data puking, where you just pour a pile of data on somebody’s desk and say, here, here’s the data.

And they’re like, What am I supposed to do with this is not helpful.

Part of the reason why it takes so long to change people’s minds is they don’t see that the decisions that you make from data are any better than the decisions that you made without the data, right? If, especially in cases where the data is confirmatory, where it says, Yeah, you know what, you made the right choice all along.

And people go, why do we spend, you know, x months and X dollars? doing this exercise, you’re gonna tell me what I already knew.

That’s where you have to take a step back and say, okay, is being data driven, a good fit for the organization, and there are organizations where it is not, for good or ill, there are situations where it’s an uphill battle, and you won’t realize any benefit.

Particularly if you have people who are not just hesitant, but outright hostile, that is a boulder as a hill, you don’t want to push a boulder up.

So being data driven, means making decisions with data.

And as with everything, the easiest way to get people to change how they do things is to show some wins, show some early easy wins, that can help you build momentum for strategy, especially if it’s something that requires very little effort on your part, and can show somebody Oh, this is really cool.

Like, I didn’t know that real simple example of you fire up Google Trends, right? And you can show just some basic search volume changes in something that a person cares about, and go, Oh, ha, I didn’t know that people searched more for my product or service in June, I thought they were searching more for in in August, when we typically see them in our CRM, and you can say, No, that’s true.

People are searching for our product or service or whatever, two months before they contact us.

So we can market to them early and think, Oh, that’s a decision, I understand.

I’m going to market to them when they’re looking for it.

And they’ll be more likely to buy it.

So it’s looking for the early easy wins as best as you possibly can to build momentum for data driven strategy.

strategy in general, but data driven strategy in particular is a sale.

There’s a reason why when we talk about getting agreement on something, it’s called buy in, right, somebody is buying our strategy.

And what is being exchanged is their time, their resources, possibly the people, certainly their patients are all currencies, of buy in to a new strategy.

And yet, we do not approach strategy as a sale.

Right? We’ll talk about all this this is the the trend that the industry is going in, or this is best for the organization.

Right? How does that work? When someone’s trying to convince you to buy something? It doesn’t I there’s there’s no compelling value there to you.

So when we have to approach data driven marketing, and data driven strategy, we’ve got to approach it from the perspective of a sale, not what’s best for the company, not what’s best for the analytics department or the IT department of the marketing department.

But what is best for the person that has to buy in? What’s in it for them? Right, every sale has to answer the question, what’s in it for me for the buyer? Are we going to give the buyer of our data driven marketing strategy, better results? Are they gonna make more revenue? Are they gonna hit their numbers more easily? Are they gonna look better in front of the boss? What is for sale? What? What is it that they said, You know what? I want that? That looks good, I want that.

And a lot of the things that we put in front of somebody for a data driven strategy aren’t all that appealing.

Right? Oh, it’s, it’s the way the technology is moving.

Great.

That’s not a compelling reason to buy something.

Right? Just because a company comes out with a new smartphone.

And it’s like, minuscule differences from the model you have? Is that a reason to buy it? No.

Right? You have to have some compelling emotional reason for the person to buy in to data driven strategy.

So because we’ve always done it this way is a position of security is a position of comfort.

The buy in, therefore is discomfort that someone is buying in with their discomfort, what do you have to sell, that makes the discomfort worth it? So early wins, easy wins, look at things that don’t require their data, look at search data, look at social media data, look at media data in general, look at data from your existing systems, and what can you say like, Hey, this is a decision that we would make better if we had this information, or Hey, I looked at the data.

And have you tried doing it this way.

And instead of being a hard pressure sales person, right, which nobody loves those, be a consultative salesperson, right? Think about it as How can I counsel and advise this person to make the right choice for them, to show them that the value of what they’re buying is worth it is worth more than the investment they’re making.

And present your data driven strategy that way as a trusted advisor, rather than using role power in an organization use relationship power.

That’s how you get buy in, that’s how you get someone to adopt a data driven strategy is to say that I clearly see what’s in it for me, I want to buy that I’m comfortable enough to being uncomfortable, because I see the benefits of what’s in it for me.

And that requires a lot of hand holding, right? Because anytime we’re going to make a major system change, for example, switching from Google Analytics, three to Google Analytics for because it, it offers you more flexibility.

flexibility in this case is kind of intangible.

And there’s a lot of pain associated with that change.

So what is the thing that you can show that says, oh, wow, that’s really valuable.

We got to make that change, because I want more of that.

Right? So that’s the way that I would approach getting someone to make a change, for adopting a data driven strategy.

Standard is to say, when you do what you’ve always done, you’ll get what you’ve always gotten, and if you’re happy with what you’ve gotten, okay, but what if you could get this instead? What if you could get, you know, 20% better results? Would you want to be able to show your boss 20% growth or whatever the number is will based on your own research that you’ve done? That’s how you get by it.

Then we go.

Yeah, I kind of want that.

You Ask, I Answer: Measuring Social Media Impact on SEO?
Sergey asks, “Is it possible to measure the impact of your social media on SEO? If so, how would you do this?”

I’d look at content which has been socially shared and its SEO performance versus content that has not been. Using the SEO tool of your choice, extract the data and look at the difference in the metrics to get a sense of the correlation, then set up a testing plan to establish causality.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Sergei asks, Is it possible to measure the impact of your social media on SEO? If so, how would you do this? So that’s a good question is one that comes up a lot? Can we make any informed guesses about how social and SEO may work together? Can we see an effect of social media on SEO? That’s a really good question.

And there are a few different ways to handle this.

The Gold Standard would be to set up a trial to set up an experiment to create some content that is socially shared, and some content that is not.

Here’s the challenge, you don’t have control over the audience, right? If you publish a blog post, and your audience follows it, and they start sharing it, well guess what they technically ruined your experiment, even if you didn’t want that shared, because that’s just the nature of how social media works.

So to judge whether or not social media and SEO have any kind of relationship we have to do.

It’s essentially propensity matching to try and create, in retrospect, those two sets of data, one set of blog posts or content of any kind, that has not been shared, and one set that has been.

So how do you do this? Well, we would take data from the SEO tool of your choice, I’m going to use h refs here, which is one of the tools I like using, and let’s go ahead and type in my blog here.

And what I get is, you know, some of the blog posts on my website, and let’s go ahead and remove that filter there.

And when you look at this, in depth, when you look this up close, what you get are the traffic, that a site gets the number of referring domains to that URL, which is a good SEO indicator, right? Because we know that referring links and referring domains are still the bulk of what constitutes good SEO, and then the social shares for any given post.

So what do we do with this information? Well, it’s difficult to do a mathematical analysis like this just as is because you’re going to run into what are called balance problems.

Especially if you’re dealing with marketing content, or stuff that’s been marketed to people, again, you don’t have control over who shares what so you’re going to get an imbalanced data set where more content has been shared, and probably that has not been.

So in order to get a true apples to apples comparison, we have to separate out similar apples from both buckets.

Apples, in this case, content that has been shared content has not been shared, that are similarly shaped, right, if again, if you think about physical apples, if you’re trying to compare, you know, the average health of apples, you have one basket of apples, where the apples of the size of basketballs and the other basket where the apples of size golf balls, you’re going to get a very different result, even if there’s tactically the same number of apples in each basket, because they’re just wildly different.

So in order to get a true compassion, we will want to find blog content, or whatever content that has similar traffic, or similar referring domains or other similar SEO measures, and some and similar social stuff together.

So here’s how we do this.

We start by going in the data.

And then we essentially pair it up, you know, one to one for data that does that is similar, and that, and then we look at the difference between those two datasets.

So what we see for this match data is that for content that has been socially shared, we’re gonna call that our treatment group.

Because we’re going to look for any number of shares in Twitter, Facebook, or Pinterest, the lump that together and call that a one like yes, this has been socialized, socially shared, and they’re all three rows of zero, we call it a zero, like has not been shared.

So we have our control, the stuff has not been shared, we have retreated, the stuff that has been shared.

When we look at the traffic, what are the traffic differences? For stuff that has not been shared, on average, 38 visits from organic search on stuff that has been shared ad visits from organic search on the traffic on the number of free domains 10 referring domains on average, the mean for non shared 46 for shared.

Now, what does this tell us? This tells us that stuff that has been shared tends to have better SEO metrics out of this pool.

In this case, this was 36,000 pieces of content.

In this particular selected group.

Now, this is marketing content, right, largely to marketers.

And so you would have to run this on your own content, right on your own website, with your own social metrics to do the same thing but for your stuff.

This is not gospel.

This is not generalizable This is mostly my stuff.

And so I see that for my SEO efforts, social sharing seems to have a beneficial relationship to it.

Now, here’s the catch.

This is retrospective, right? And this is as good as you can get with causality.

Unless you actually set up that experiment you eat again, even then you have no control over what other people do so like the other people can mess up your experiment.

So by doing this kind of matching, this is as close as we can get in with real world data.

I take this away to say that sharing has benefits for my SEO.

And in some cases, like the number of referring domains, it’s substantial, right? It’s it’s a decent chunk of stuff.

What do I do with this information? I keep sharing, right? If I saw that, there was no change between the control and the treatment.

In my data.

I go, you know, it doesn’t seem like you’re actively sharing and promoting stuff on social media has an impact.

But I do I know, I, I share an awful lot on social media.

And so I see the benefits of it here.

This is how to measure that impact to get a sense of is it working? The challenge here is it doesn’t tell you necessarily ways that you can measure the say in an application like Google Analytics, we had to pull an SEO data from social data from a third party application.

I would want to ideally substitute in Google Analytics data, if possible to match things up by URLs because Google Analytics has better data.

And you can get paid level organic search data straight out of Google Analytics.

So that’s the approach I would take to find out, does social media have any kind of impact on your SEO? And again, I can’t emphasize strongly enough, this is my data from my websites under my control.

This is not other people’s stuff, your answer will vary.

Your answer will vary.

So please don’t assume that this applies to you.

Right, you have to run this test for yourself.

But it’s a good question.

And and it is a statistically challenging question to answer.

There are a number of techniques that try to take real world data and backfit it essentially into an experiment like setting to get a more clear answer.

This is one of the better methods, it’s called propensity score matching.

But you have to do it for yourself, you cannot rely on a third party to do it.

You can’t even rely on an industry, industry level survey because again, everybody’s gonna be different.

Right? What IBM does on its website, it’s gonna be very different than what I do with my website.

And their content is different than that’s, you know, what marketingprofs does on their website is very different from what’s on my website.

And so we have to, we have to do apples to apples with our own stuff as much as possible and not look to general industry examples.

So good question.

You Ask, I Answer: Social Media Engagement and SEO?
Sofia asks, “Do social media likes, shares, and comments have an impact on SEO?”

This is a tricky question to answer because the answer will be different for every company. Broadly, we’ve studied in the past and see no clear correlation, but it’s something you have to test for yourself.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Sophia asks, do social media likes shares and comments have an impact on SEO? Well, so this is a tricky question, because the answer is going to be different for everyone.

A long time ago, we did a big analysis of 10s of thousands of websites, and social shares and stuff like that.

And broadly found there was not a strong correlation between social media activity and SEO.

That said, it varies, it varies by company and by how you use search, because remember, the strongest predictor of SEO results is typically the number of inbound links that you get.

If you are conducting your social media strategy for that purpose, getting people to find your content, getting people to link to your content, social media may very well deliver a strong SEO result.

If on the other hand, you just sharing stuff and things and, and having conversations and being active in your community, then it may not have as strong result for SEO purposes.

And I think that’s a really important thing to say is for SEO purposes, you have to measure very specific outcomes, as opposed to just general traffic, etc.

So how would you know this? How would you know this? Well, the way to determine this is by using statistical tools to test you need your page view data from Google Analytics, you need your paid organic page searches from Google Analytics to see if you’re getting search traffic.

And you need some kind of SEO metric like page authority page authority is available from almost every SEO tool out there.

h refs, which is the tool that I use, delivers that so to do the others like SEMrush, and Moz, all these other ones.

And, again, what we’re looking for is what has the highest mathematical relationship to that.

So let’s flip this around here.

What I’ve done is I’ve gone into my database, and I’ve pulled in 800 pages from my website with Google Analytics, traffic numbers, and pageviews, clicks.

Facebook shares, Twitter shares, Pinterest, Reddit, no word length number of words in the article from my database, where I have pageviews, and I have social shares.

And we’re going to run it through a regression algorithm, this case gradient boosting, to figure out what has the highest relationship to the metric we care about, which in this case is going to be that page authority.

And what we see here is that for page authority, total inbound links is the strongest predictor, it’s hands down the top predictor.

And we see two weak predictors, content length, and Twitter shares.

They’re the Twitter shares, one is a very weak predictor, it is not, I would not bet the farm on this, and then Facebook shares and Pinterest, you know, nothing.

Nobody’s home, and Reddit didn’t make it on here.

So for my website, if I want to predict what leads to higher page authority, it’s going to be total links, I’ve got to go get those links and social shares, at least the way I’m using social media right now.

Clearly not using it for SEO purposes.

Right? There’s just no evidence of that for my website.

Now, here’s the question, is that a valid metric is that what we should be focusing on? I would argue that probably it’s not going to be as good as if I focused on something like pageviews.

Right pays you seems to me like it’d be a slightly better thing to focus on.

So let’s rerun this model.

If I want actual traffic, and see what the machinery comes up with here.

Now while it’s doing this, again, one of the things that we have to give some thought to is are we focused on the right metrics? Are we focused on an SEO metric? Or are we focused on an outcome? In this case, I’ve just changed the outcome to page views, how much traffic did I get to these from any source from any source.

And again, we see here page authority, a very strong predictor of traffic, right? And content length, a very, very strong predictor as well.

So if I want more traffic in general, I should focus on these things then total links is a is a medium predictor.

Facebook shares becomes a medium predictor.

So that’s interesting.

In the previous example, we were focusing on an SEO metric, Facebook didn’t make the cut.

If I focused on getting people to my page, Facebook is a usable metric here, Facebook shares, number of shares that my content gets.

It is not SEO.

Right? Facebook is not usable for SEO.

If I click back to this previous plot, we can see, I’m not getting page authority.

But here, total links, content, word count, are for traffic, and then Facebook for traffic, Twitter, not so much Pinterest.

And of course, Reddit still didn’t make the cut.

That probably has a lot to do the fact that I don’t really post on Reddit.

So the question we have to ask ourselves from a strategy perspective is which metric? Are we going after more? I would say that page authority being the highest predictor of traffic means that yeah, it’s probably a good idea for me to pursue an SEO strategy.

And then knowing that I can then focus on the thing that drives that strategy, which is getting inbound links.

How do I go and get those inbound links? Clearly, I don’t do it with social media.

So I have to be able to do it from sub some other way.

And I would have to look into my SEO processes to ask, what should I be doing? To get that, to get those links? Do I need to be doing more outreach? Do I need to be creating better content? Do I need to have a PR firm representing me? Do I need to be pitching journalists on Twitter? It doesn’t really matter.

As long as I’ve Well, it doesn’t matter.

But what I’ve ascertained here is that for SEO purposes, social media, not super important for traffic, social media is a little more important.

And I think that that’s a really, really important thing for you to do before you go trying to figure out, is social media, a way to drive our SEO strategy, figure out do you is your SEO strategy working? And then go and bring that information in? So that’s the process for doing this now.

Is this something that anybody can do? Absolutely.

And you don’t have to use this environment.

This is a tool I’m using called R.

You can do this in IBM Watson Studio with the SPSS modeler and not have to code.

There are ways to do this in is drag and drop little widgets in here, drop your data in, and it will do the exact same thing.

And you won’t have to code it’s it’s much easier.

I just do it because it’s here on my machine.

It runs locally.

And it doesn’t cost me anything to do this locally.

IBM Watson Studio does charge you after the first 50 hours of usage.

So if it goes do this, once, it’s fine, it won’t cost you anything after a certain point, you do start running up the bill.

But the takeaway is, does social media like shares and comments have an impact on SEO? Maybe you have to test it, you have to test it with your data, you have to test it with your site and figure out if there is a relationship, is it causal? Are you using social media to try and get your SEO strategy to move forward? If you’re not, then in a relationship you have is largely coincidental.

Now there’s is a relationship like here, in this case for Twitter, you might want to think about should that be our strategy? But if you are doing it with a strong intent for SEO purposes, and you’re not getting the results, and you know it’s not working? So that’s how you use this information? Good question.

Because the answer as with so many things in data science is it depends.

You Ask, I Answer: Third Party Data and Model Audits?
Jessica asks, “When it comes to training data for marketing AI models, do you think vendors will anonymize/share data sources in the future? Will it be required?”

It depends on the vendor and the model. The raw data for public models, even de-identified, probably will not be publicly available, but should be made available to auditors. Those auditors could certify that the data used was appropriately representative and free from specific kind of biases. For vendors where we’re paying money to them for marketing artificial intelligence services, we absolutely should be seeing either audited results or deidentified data.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Jessica asks, When it comes to training data for models, do you think vendors will anonymize or shared data sources in the future? Will it be required? It depends on the vendor and the models.

So within the context of marketing, Ai, marketing, artificial intelligence vendors will be providing us access to various types of AI models, things like lead scoring models, propensity scoring models, deep neural networks, all sorts of stuff.

And what makes up those models.

Right now, the trend is very much for companies to say like this is our proprietary, you know, special, whatever.

And certainly, companies right now are not sharing any kind of information about their models, their complete and total black boxes.

As regulatory scrutiny continues to ramp up appropriately, it should be ramping up on artificial intelligence.

What goes into those models should be more transparent.

So for public datasets, public models, I don’t expect the raw data to be made available even de identified, because a, those companies probably don’t have the ability to share that at such a large scale, we’re talking massive, massive, massive datasets.

And be if it’s publicly and freely available, you get what you get, is literally, you get what you pay for.

For vendors where you are paying money to that vendor, for use of their model.

I think it’s absolutely a reasonable request to either ask for de identified data, or to ask that the company go through an audit.

Just like we asked companies to go through audits for safety, for diversity, for all these different criteria inside of an RFP, there’s absolutely no reason why adding an audit for the model of a data data from a model wouldn’t be required to be able to say, Okay, I want you auditing firm, you know, KPMG, or whoever, to inspect the data, make sure it’s appropriately representative.

And free from a specific list of biases.

You know, if you were to take the list of protected classes, and say, okay, you’re going to auditors, you’re going to go through and inspect the data, to ensure that the model is free from unfair bias ease along with these protected classes.

And given the list of biases that you’re looking for things that are legally prohibited, all those protected classes age, gender, race, veteran status, disability, gender identity, sexual orientation, religion, etc.

And those are the ones that locks talk about every single auditor would be looking to, to reduce bias on.

And then also any criteria that you would have for your company, if there are things that your company values that you would look for that are not technically illegal, but you feel are run contrary to your values, you have the auditors inspect that as well.

Now is a company got to do that for like, you know, a 299 a month SAS model? Probably not, they’re probably gonna tell you find another vendor.

But for larger models, custom developed things, you know, where you got to pay a company 5060 $70,000 a month? Absolutely.$

It’s a reasonable request at that point to say like, yeah, we’re gonna bet our business on this.

And we’re gonna bet a mission critical system on this company’s model, this vendors model, it had better be free of all these things.

It’s no different than food, right? You don’t really get a say into the ingredients and a prepackaged food if you want to certify that a food is a certain way, you got to make it yourself.

Right.

But vendors working with other vendors absolutely do have to require things like if you specify that food is organic, it has to meet the legal definition of organic and someone certifies that organic food meets those criteria and that is a legally binding requirement.

So the same thing is true when it comes to these types of models.

Now are there auditors and vendors doing this today? I don’t know that any of the big shops, you know, ei KPMG, etc.

I don’t know if they are offering this publicly as a service yet.

But it will not be long.

After the first few lawsuits where a company gets in a whole lot of hot water for a biased model, he will become part and parcel of the industry, you know, the auditing industry and it’s appropriate.

If you wanted to certify it yourself, you absolutely could.

But again, it would have to be worth the while for a company to, to do so if you’re looking for a facial recognition algorithm that and you’re paying5 a month for the company is not going to tell you whether the data set is biased against people with darker skin.

But if you’re building a mission critical app on it, you can absolutely say, hey, I need to ensure that this thing is not biased.

And I’m going to stop paying you, you know, five figures or six figures a month until you do that.

It all comes down to economics.

When it comes to your company, if your company is building models or your own plan, and build your models with the assumption that you will be required to, at some point, disclose de identified versions of the data, you obviously have to protect user privacy, you always have to protect people’s identities, especially around protected class data, and personally identifiable information.

But beyond that, plan, that somebody else will be inspecting your data at some point down the line.

So make it in a format that is you know, easily machine readable, make it in a format that it can be exported, make it in a format that all your variables are clearly named.

And obviously named.

Things like if you’re going to have gender, like have gender not, you know, attribute 56.

So that you can make the auditing process on your own data as easy as possible.

And as painless as possible, build with the assumption that somebody else at some point will be taking a look.

Not necessarily the general public, but an auditor or somebody or somebody like that.

And make your life easier.

Future you will thank you future you will thank you for for making the audit process less painful.

And because it is coming for sure.

So yeah, that’s where we are with data sources and models.

Expect auditing.

Really good question.

important question for all of us who are working in the industry to keep in mind and we have to build for it.

You Ask, I Answer: Liability for Marketing AI Models?
Jessica asks, “Who’s liable for violations in marketing AI models, the company that hires the vendor, or the vendor? Anything in service agreements to look for?”

Who’s liable when someone uses a tool improperly or illegally? Companies have some responsibility, as we see with product warnings, but the ultimate responsibility – and who gets sued/arrested – is the end user. Many EULAs shift the blame entirely to the user and force users to waive liability entirely.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Jessica asks, who’s liable for violations when it comes to marketing AI models or any artificial intelligence models, the company that hires the vendor or the vendor anything service agreements to look for.

So artificial intelligence models, some really fancy word for software, right at the end of the day.

Machines are writing software, but they’re writing their own software.

But it’s still software is still a piece of software no different than you downloading a copy of, you know, Microsoft Word, or Excel or video game.

And so the laws that apply to AI models, largely the same as the laws apply to standard software and, frankly, the laws that apply to anything.

Companies have some level of responsibility when it comes to Product use and misuse to have to warn you of things that are obviously potentially dangerous or misleading.

You know, when you look at the standard bottle of any kind of medication, it tells you, you know when to use this product directions to take it.

Don’t take it for these things.

So there’s this a little bit of responsibility coming out of the company.

But other things, you know, don’t have those warnings necessarily, because they’re not really needed.

Like, you look at the job of doing spicy peppers.

There’s no warning on here it says do not pour in your eyes.

But people do crazy silly things like you know, tide pods.

At the end of the day, when it comes to artificial intelligence, who’s liable for the way that a model behaves is ultimately up to the end user if you download a piece of pre trained software pre trained model from Any vendor, and that’s got a bias in it of some kind that is against a protected class and therefore not legal.

You, the company and the user are responsible for what happens with that.

Right? You are responsible if you use it and then and this model causes your marketing or your operations or your customer service to discriminate against somebody on a protected class, you are responsible for your actions, you are responsible for it just the same as you know, if you go out and you buy a knife of some kind and you use it in to cause somebody harm, it is not the knife minute manufacturers fault that you did something with the tool that was improper.

You the user, were the person who did the bad thing, and you are liable for it.

And that can mean civil liability, like getting sued or can mean criminal liability, like getting arrested.

When you use any piece of software these days, actually, especially when it comes to the Downloading models and data from other people, other companies, there’s a good chance you sign an End User License Agreement.

Now whether you read it in its entirety is not the company’s problem.

But chances are somewhere buried deep within that End User License Agreement is a statement that where you waived all liability and you assume entire responsibility, whole responsibility for what you do with the software.

Whether or not the software is flawed, whether or not the model is biased.

Whether or not the training data was any good to begin with or not.

There is a good chance that you have incurred 100% of the liability especially if you’re getting it from a major commercial vendor like Amazon or Google, or IBM or anybody, there’s a good chance that you are assuming 100% of the risk.

Now, if you are publishing data sets, if you are publishing pre trained models, you definitely want to talk to Your legal department to effectively do the same like, hey, we’ve done our best.

And maybe, you know, as as we were talking about, you list the ingredients and where you got the data, its provenance things.

But you definitely want disclaimers of that, as well to somebody downloads your data, your software, etc.

Your models, you want to say, hey, we’ve done our best.

We know there may still be issues in here, but you the user, assume 100% of the liability for how you use this, then you cannot hold us liable if you make a piece of software that discriminate against discriminates against people who are, you know, transgender, guess what, that’s not our fault.

That’s not our problem.

from a legal perspective, it is your problem as the user of the software.

It is your liability for you have to take ownership of your actions.

In terms of service agreements, you’ve got to read them You’ve got to read them.

And especially before you pay money to anybody, you’ve got to read them to understand what they are and are not accepting responsibility for.

And do that due diligence of look inside their documentation to the best extent that you can.

If you’re going to be paying money to this vendor, you can ask that as part of your due diligence to say, give me your data lineage.

Give me your data, provenance.

Give me your model governance.

Show me how you’re keeping the model from drifting Show me.

Any known issues, you know, just like you buy a house.

Yeah, have a house Inspector, and they come in and tell you Oh, yeah, it looks like there’s a leak there.

Like it’s old, but there’s definitely a was a leak there.

And that’s out of out of code.

You want to do that same level of due diligence with any models or software that you’re working with to say to the vendor.

Hey, tell What you’re known issues are disclose any material conditions that could cause issues at the vendor says we don’t have that documentation.

No, sorry, we don’t have that.

Don’t do business with them.

The same as they said, Oh, we our model is totally fine.

There’s absolutely no bias in it.

So we don’t have that documentation.

Okay, that means you didn’t do any checking, because almost every model a data set has some kind of bias in it, whether it’s material or not, meaning has constant is consequential or not is is secondary, but even in the the weekly newsletter, I publish to the Trust Insights newsletter, whenever we publish a study we disclose the methodology and say like, you know, for example, with SEO, this is limited to the English language.

So it automatically has a bias in it is that bias material, maybe, maybe not.

But if every vendor who publishes any kind of data models, algorithms, should be saying these are the nodes biases in here.

take that with a grain of salt, right? If If you feel like the data set needs to have more than just the English language and for SEO, then our data would not be helpful to you.

Right? There’s that disclosing of known biases, that’s the sign of a more mature vendor.

they’ve they’ve got their documentation order, they got the disclosures in order.

They’ve told you what they know is wrong.

And it’s up to you to decide whether those things are important to you or not.

So, really good question on liability at the end of the day, remember, it comes down to the the tool manufacturer is not responsible for what you do with the tool.

You can do good things with it, you can do bad things with it, but at the end of the day, they’re not liable for you are so that’s the rule to keep in mind.

Has any of this been settled in court? Not that I know of but I also have not done a whole lot of checking on fine law but based on existing software, Law based on existing general liability law and what and I’m not a lawyer and disclosure, I’m not a lawyer, check with your own legal counsel.

I don’t think aliens has come up in court yet.

I’m sure it will at some point and it based on existing law, the courts are likely to rule that unless you were intentionally negligent or willful in the creation of your model, that you’re the software manufacturer is probably not responsible for it.

You Ask, I Answer: Vetting Marketing AI Vendors for Bias?
Tracy asks, “What are some questions you should ask vendors to better understand what data they use in their algorithms to make sure it’s not biased?”

It’s not just questions we need to ask. Consider checking for bias to be like any other audit or due diligence. We will want to investigate the 6 main areas where bias creeps in: people, strategy, data, algorithm, model, and action/deployment. How do you do this? A lot of it comes down to vendors producing documentation. If they can’t, there’s likely a problem.

In today’s episode Tracy asks, what are some questions you should ask vendors to better understand what data they use in their algorithms to make sure it’s not biased? So it’s not a question.

Well, it’s just questions we need to ask.

bias is like any other any other professional vetting that you want to do in that there are things to look for, and things to request from a vendor in the same way that you would vet a vendor for equal opportunity, employment for non discrimination for fiduciary responsibility.

There are so many different aspects to auditing and doing your due diligence on a company and checking for bias and artificial intelligence and machine learning models really shouldn’t be any different than checking to see if a vendor is You know, title seven compliant, right? If the vendor discriminates against people in hiring, you probably would want to do that.

Know that, you know, when you look at any of these audit forms you’re required to fill out if you’ve ever been through a corporate audit or delightfully fun.

But there are lots of questions about, you know, what’s your process around hiring, what’s your process around alignment to the Equal Opportunity Employment Act, all these different ways to look for problems.

When it comes to bias in AI and dealing with vendors, it’s important to understand what kinds of bias to look for there’s six places you want to look for it and we’ve got other videos in the show.

If you want to head over to the YouTube channel, you can see better definitions and stuff but the six areas we’ll bring this up here, the six areas where bias creeps in, in AI and machine learning are people strategy, data, algorithms, models and actions as So let’s talk about each one of these as it relates to a vendor.

Number one people is easy.

Who is has been hired? Right? Who are the people working on the models and algorithms? Who are the people building the software? If you look at the development team, or the engineering team, and you see a complete lack of diversity, there’s probably going to be a problem, right? Even if it’s not intentional, just having a monolithic view of the world, if it’s a bunch of, you know, say 20, mid 20s, Caucasian males, that’s your whole development team.

They have a natural mindset that does not include people who are black because they’re not in their experience, right? It’s not saying that they’re, they’re bad people, just they simply do not have experience if none of them are female.

They have no frame of reference for things that females people who identify as female might be interested in, right? So that’s an easy one.

Look at the people look at the composition of the people.

Look at the diversity of the people and if you don’t see any diversity, you know, there’s a problem.

This, by the way applies not just to AI and machine learning, but to every vendor.

If you’re hiring like a PR agency, go to that agency’s leadership team.

If you see a whole bunch of people who look exactly the same, there’s a diversity problem there is, which means there’s a diversity of ideas problem.

second strategy is where bias can creep in, what is this the the strategy that somebody’s going for? Really good example of this.

Facebook has a strategy of engagement, right? They care about getting eyeballs stuck to their site, which means their algorithms tend to promote things that keep people engaged, like making people angry and afraid all the time.

And so they’re, the outcomes from that strategy have been, as we’ve all seen, pretty substantially negative, right? We’ve seen a flourishing of hate groups and all these things because that’s the strategy did They intend to allow like Nazi groups to flourish? Probably not.

But is a natural outcome of an incomplete strategy or strategy that was not informed by a diverse set of objectives.

Yes.

Third, data bias creeps in, in data.

Where did the data come from? Right, where this is what’s called Data lineage or data provenance.

How good is the data? Is the data itself balanced? Is it representative IBM has a fantastic toolkit called the IBM fairness 360 toolkit.

If you’re fluent in Python, you can download this for free, run it on your data, declare any protected classes things like age, gender, veteran status, disability, sexual orientation, gender, identity, race, religion, and in your data, it will then say hey, this model does not look representative or this model has a lot of drift or this model is the state is likely to behave badly.

So checking your data To the lineage of the data is important where the data come from.

If your data came from sources that themselves are biased, that can be a big problem, for example, black American healthcare, all the data is wrong, right? Because of systemic racism, you cannot get really good large scale data on black American healthcare because there isn’t good data.

systemic discrimination has created an entire pool of corrupted data.

Number four algorithms.

So the algorithms are the individual choices that you make, for what your models going to do, what strategy you’re going to pursue from an algorithm point of view.

This is things like deciding if you’re going through a gradient boosting now or generalized linear regressions, all these different choices.

Bias can creep in here because if you have somebody who doesn’t understand the full objectives and doesn’t have a background in diversity, they may choose a competition.

efficient algorithm, but not necessarily one that is fair.

So this would be a case for example of using something like a straight up a gradient boosting model versus something like Pareto multi objective optimization.

The algorithms are very different.

Pareto optimization allows you to essentially do what’s called trade off analytics, you will get a less well performing model but it it performs against, you know, many many different objectives as opposed to one objective kind of like what Facebook versus like LinkedIn how they function, they function very differently because of their optimization algorithms.

Number five, the model itself the model can drift.

The model when it takes in data as it takes in new data over time, it can drift the most famous example this is the Microsoft tape chat bot, which was corrupted by trolls basically, within 24 hours, it became a porn spewing neo nazi chatbot It was a train properly, but it drifted and drifted it didn’t have guardrails to keep it on the rails.

So that’s a place where bias can creep in.

And last is the actions.

What do you do with the model? Right? What do you wear? What are you going to use this model for? This is a good example of this is a martech vendor I saw that was effectively reinvented redlining, right they they built a tool to identify ideal customers, and it reinvented redlining.

And so bias crept in and in what their model was going, they’re going to do with the model.

So that’s a very short period of time at all the places that bias can creep in, throughout the process.

When you’re auditing vendors, when you’re doing your due diligence, ask them for their documentation about how they prevent bias in each of these areas, right.

You would not get on a plane.

If you walked in the cockpit and you saw there was no quick reference handbook.

There was no preflight checklist and you know, the pilots are just kind of winging it right? They do not get on that plane.

Because that is an unsafe play, and there’s no documentation, there’s no process, there’s no validation that things are working as they should be.

The same is true with AI and bias, right? If a company has no documentation, no processes, no rigor, no checking for bias in each of these areas with real checklists, like real document checklists, here’s the bullet points that we look for at each stage of our projects, then there’s a good chance by scrapped in, and in turn, that means there’s a good chance that the what they produce is also biased too.

So look for those ask for those as part of your process, and if they can’t produce it, probably a problem.

Right? That’s the the easiest way to vet a vendor, ask them for the documentation called part of compliance or whatever.

And the vendors themselves should recognize that if they don’t have this, they themselves are at legal risk, right because they can’t prove then they’re not biased.

So, great question.

We could spend a whole lot of time on this.

Great question.

You Ask, I Answer: Difference Between Fair and Unfair Bias?
Gianna asks, “What’s the difference between fair and unfair bias? What’s the fine line?”

Fair and unfair comes down to two simple things: laws and values. Statistical bias is when your sample deviates from the population you’re sampling from. Bias isn’t inherently bad unless it crosses one of those two lines.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, john asks, What’s the difference between fair and unfair bias? What’s the fine line? So fair and unfair bias really comes down to two simple things, two very straightforward things, laws and values.

So before you deploy any kind of models, or build any kind of artificial intelligence systems, you need to understand what bias is.

bias is when your sample your data, your whatever it is you’re working with, in some way statistically deviates from the population you’re sampling from.

And bias doesn’t necessarily have to be good or bad.

It just is.

It’s a mathematical concept, at least in the context that we’re using it here there’s human bias, which is totally separate from statistical bias.

For example, you may want to sell your product to people who have higher incomes.

Right? That is allowed.

Certainly, it makes logical sense.

And income is one of those things that’s, you know, under somebody’s control to a degree whereas, say their race, they are not under any control of it, they have absolutely no choice in what race they are.

They have no choice in what age they are, etc.

So, when you’re talking about what’s fair and unfair, we’re talking about, are we building tools that disadvantage, a population on in some way that is either against the law or against our values, and the two may not necessarily always agree, there are plenty of things that you may decide as a company or as an individual, are unacceptable to your values, even if they are technically legal.

Right.

You may decide you don’t want to say include, gosh, firearms owners or coffee drinkers.

From a, you know, doing business with you, and that’s totally fine because neither of those things are what’s called a protected class.

protected classes are and this depends on where you live where you work where you do business, the laws change from principality.

protected classes are attributes that are protected under law.

In the United States, for example, age, gender, sexual identity or gender identity, sexual orientation, race, religion, religion, and credo are protected, veteran status, disability, these are all things that you may not discriminate on and have been held up in court.

Any number of times to say these are not permissible things to discriminate on.

And so when we talk about fair and unfair bias we are talking about does your software which is what an AI model is does your software in some way disadvantage.

What people on one of these attributes, if your software says that, you know, we’re only going to show our products to white people, that would be illegal, that would be a, a, an unfair bias along a protected class.

And again, you may have values that add additional things that you don’t want to discriminate on that you don’t want to advantage or disadvantage somebody on.

Likewise, you bias is also something that where you advantage in one group of people over everybody else, so it doesn’t have to disadvantage one group, it can just it can disadvantage everybody except one group.

So bias isn’t inherently bad unless it crosses the lines of laws and values.

Now where this gets into trouble for AI and machine learning and data science is not necessarily in the protected classes, not even necessarily in the ethics and values, but in how machines use data.

And, in particular, this is deals with correlates.

So a Carla is when you have a variable or a group of variables that behave very similarly.

So there is a strong correlate in, at least in America, for example, between income and race, there is the, the more of a certain race you are, the more probably your incomes higher or lower.

And so if we’re building a machine learning model, say to only be able to demonstrate to show our ad or our system for our, you know, what we want for customers or who gets in line, who gets privilege treatment.

And we’re doing it on income level, we are potentially also discriminating on a protected class, right? Because, again, there’s a strong correlation between race and income.

So one of the biggest challenges that folks in the machine learning and AI space need to be addressing is doing things, you know, doing matching doing propensity scoring, doing regression analysis that demonstrates that the algorithm is discriminating on things that are permissible and is not discriminating on things that are not permissible.

So, for example, if I’m selling high end coffee, right.

And I want to discriminate on income level, which is permissible.

I also have to be able to demonstrate through statistical testing, that, say, a black family with the same income level as a white family is just as likely to be shown our ad as the white family, right.

Being able to say like race in this case is not a discriminating factor.

Like if you are black and you have above a certain income level.

You are just as eligible just to see our ads.

If, but what will happen in a lot of cases is that people don’t do this testing.

People don’t do this inspection of their own.

And the outcomes, and they end up discriminating.

And whether or not the intent was to discriminate does not matter, it’s whether you actually did.

Because in a court of law, you will be held accountable for your actions.

It’s like, you know, I didn’t mean to hit that guy with a hammer, I just hit them with a hammer really hard, I’ll know does doesn’t mean intent means nothing, you hit the guy with a hammer.

The same thing is true here, where you may not have intended to discriminate along racial lines, or gender identity lines or veteran status, but you did, and you were liable for it.

So a huge part of the work in AI and machine learning is to know to look for bias to test for it.

And then to test for correlates to things that are not allowed things are out of alignment, the laws and values.

And this requires money and time because these are expensive processes to go through and essentially deconstruct a machine learning model to understand how it’s making its decisions.

And it requires a willingness to do so.

Now, if the company you’re working for or the project you’re working on, the stakeholders say, No, we don’t want to do that, then at that point, you are personally liable for outcomes.

Because at best point you may have said, I know there’s a potential problem, I know that we may be doing something wrong.

If you don’t take action to correct it.

You’re by definition an accomplice.

So be aware of that.

But a lot of what’s happening in machine learning really comes down to those correlates.

And you just have to test for them you have to investigate, you have to know that there could be a problem.

And that brings me to my last point.

You have to be asking these questions of your models.

Do not assume that the software knows to look for bias because most software out there a few notebooks options like IBM Watson Studio Studio do know to look for it.

But most software doesn’t.

Certainly anything you code yourself does not inherently do that unless you put it in.

So you need to be building that in as a process in your systems so that you are looking for fairness, you’re looking for unfairness, you’re looking for discrimination from the get go.

And that can happen in the data that can happen to the people you hire to work on the data.

It can happen in the model.

And it can happen in the model after deployment, where you get something called model drift where the model starts behaving in ways you didn’t intend it to.

So looking for unfair bias isn’t something to do one time it is an ongoing process when you’re working with machine learning tools.

So really good question.

Where’s a lot to unpack here.

There’s a lot to talk about when it comes to bias in machine learning, and AI, and in general, but these are things you must be aware of in order to reduce your risk to reduce your liability to reduce the likelihood that you get sued for You know, thousands or millions of dollars?

You Ask, I Answer: Third Party Data and Trustworthiness?
Ashley asks, “If you choose to use public datasets for your ML models, like from Amazon or Google, can you trust that those are free of bias?”

Can you trust a nutrition label on a food product? The analogy is the same. What’s in the box is important, but what went into the box is also important. Trust is also proportional to risk.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

In today’s episode, Ashley asks, If you choose to use public datasets for your machine learning models, like from Amazon or Google, can you trust that those are free of bias? Hmm.

Well, so there’s a couple different things here.

companies like Amazon and Google don’t typically offer data sets.

What they do offer are either models or API’s of some kinds.

So Amazon, for example, has recognition and sage maker and all these things.

These have API’s behind them.

They have pre trained models.

Google, many of the services in Google Cloud perform the same way.

For example, Google speech to text, things like that.

Google also does release actual models themselves, like the T five transformer library, which you can install into like Google colab or your local Python environment and use their pre trained models.

And then there Yes, For example, Google datasets does offered raw data.

Now, let’s talk about that.

Can you trust that these are free of bias? In a word? No.

In order you cannot blindly trust anyone’s machine learning models data is to be free of bias because you don’t know what’s in it.

So as an analogy, suppose that you have a jar of jalapenos, right? A nutrition label that has five calories per serving.

And what would I expect to see in this jar jalapenos, right as an ingredient and probably vinegar and water, right? Because that’s maybe some salt.

That’s what’s in here.

Can I trust that if I just look the label alone that that’s what I’m getting? Well, when I look at this, I go to jalapenos water vinegar, salt, dehydrated onions, dehydrated garlic, calcium chloride is a firming agent.

sodium benzoate.

is a preservative polysorbate 80 which is that in their tumeric for color, why is polysorbate 80 in here, you don’t need an emulsifier For, for peppers in a jar anyway.

Can I trust? What’s on the label? Can I trust that what’s on the label is is accurate.

For example, we had a dolloping, where they jalapenos grown, where they grown free of most no harmful pesticides.

This case this jar is not labeled organic, so probably not.

On the other hand, if you were in the EU and you had this exact same product, could you trust that it was free of pesticides? Yes, much more so because EU regulations for foods are much more stringent than the United States.

The same analogy applies to machine learning and data science.

What the model says is important but also what went into the model to make the model is just as important to be free of bias to be free of both kinds of bias both human and statistical.

There are for example, any number of cases Is of bias that was unintentional.

Somebody did not mean for the dataset to be biased or did not mean for their mouth to be biased, but it was because they didn’t do any due diligence when putting it together.

Most probably famous case of this is Amazon when it attempted to build a hiring AI to screen resumes.

They trained it.

They weren’t looking for bias, and the model stopped hiring women.

Right? Because nobody did any checks.

So what’s the solution? Can you build from these systems and trust them? Well, there’s two different ways to handle this first.

The first is to build your own model, which is expensive and time consuming, but it is the only guarantee that the data going into it is trustworthy because you will have vetted it and made it trustworthy and tested it.

If you are somewhat familiar with Python.

IBM has the fairness 360 toolkit which is a phenomenal toolkit, totally free, totally free to test datasets for bias.

And if you are building your own model, you would use that to validate your data before the model is constructed.

And then you can be reasonably sure that your model is free of at least of data going in being biased, you do still have to monitor it, you still do have to have for example, the protected classes that you’re monitoring for declared.

And you still do have to ensure that the model when it’s running is not drifting out of the rails that you set for it the guardrails.

For example, if you said that you know, gender must be 5050 split for 4040 1040 4020 then you would have to monitor and say okay, how far outside is acceptable, you know, is a 1% drift acceptable is a 5% drift is acceptable At what point To say, Hey, we need to either ran the model back and retrain it, or balance it in some way to get it back on the rails.

So that’s one aspect is the, you have to build it yourself and train it and monitor it to is a risk judgment.

Try trusting a model is proportional to the risk that you’re incurring with the model.

So, if I am building a machine learning model to recognize sentiment in tweets, how vitally important is that going to be? No one’s probably going to die.

If I’m using it for like social media engagement monitoring, probably nobody’s going to die.

I might make some bad judgment calls, I could cause some damage to a brand.

But for the most part, it’s not super serious.

On the other hand, if I am producing, say, a new vaccine it had better be really, really, really biased It better be really representative had a better be really any model I built to try and assess the efficacy of something or identify a drug candidate had better be pristine and it’s freedom from bias because it could actually kill people right the risk level is substantially higher.

So, the the standards that we must hold that model to are much more stringent facial recognition for say like at a tradeshow booth, relatively low risk, right if you miss identify somebody for you know, as as a gimmick to attract people to your tradeshow booth, not huge facial identification being misused by police, big deal, a life threatening deal.

So you had You’d better make sure that that model is properly trained and unbiased.

So that’s how to evaluate you know a lot of these models and data sets and pre trained models and API’s from major vendors.

Is was level of risk and what is or consequences if it gets it wrong.

Bear in mind that an awful lot of machine learning models are biased especially in facial recognition.

And in natural language processing.

Natural Language Processing has a lot of hidden biases, the most obvious one of which is most of them are trained on the English language and English is, I forget who said it is a language of privilege.

It is the language of the wealthier part of the world.

It is not the majority language in the world.

And there are many, many, many, many billions of people who speak other languages.

And many of our machine learning models are not well suited to recognizing or processing those models.

And if you think some of the things that AI does with English are hilarious, you should see what they do to other languages.

When you give that some consideration and who speaks English and what race they are, and what gender they are, and what income level they are, what ethnicity they are, what religion they are.

You can see how even something as simple as using the English language could introduce biases into your models.

So keep that in mind.

It’s all about trust and risk.

How much trust Do you need in the model? How high is the risk, and that dictates whether you should be training your own versus using a third parties.

If you have follow up questions, leave them in the comments box below.
