    You Ask, I Answer: Classes of Problems AI Solves in Marketing?

    Annika asks, “Important functions of AI with big data are analyzing the past, predicting the future and prescribing future strategies according to the marketing AI institute. What else do you know to be important use cases for AI in marketing?”

    One of the most important things we need to understand is that AI isn’t just a collection of random solutions and operations, any more so than math itself is random. There’s a defined structure, a framework, of problems that AI is good at solving. Once we understand that framework, we can begin translating it to real-world applications.

    In today’s episode Anika asks, important functions of AI with big data are analyzing the past predicting the future and prescribing future strategies, according to the marketing is to what else do you know to be important use cases for AI and marketing.

    So this is one of the things, the most important things we need to understand about AI is that it isn’t just a collection of random solutions and operations, right? What what we have happening here is an attempt to try to understand what AI can do, and, and conflate it with business outcomes.

    And those are two different things.

    So what we need to do is dig into the operations, the capabilities of AI machine learning, particularly, and understand that framework first.

    And that it’s not random.

    And it’s not just a collection of disconnected point solutions, understand the framework, the structure first and then apply it to the business outcomes we care about.

    So let’s look at what this framework looks like Michael is bringing it up here.

    So artificial intelligence, machine learning in particular, is good at four types of problems, right.

    In the upper left, you have well, you have two types of out of problems you’re trying to solve either know the outcome you’re looking for, which is called supervised learning, or you have you don’t know what you’re looking for, you have a big pile of data and you’re trying to make sense of it.

    That’s called unsupervised learning.

    So that’s the top.

    along the left hand side, you have two types of data, you have have numbers, continuous data metrics, and you have non numbers.

    So stuff that’s categorical nature, dimensions, descriptors, things like that.

    An example of continuous data, of course, is any kind of number.

    categorical data would be things like place names, channels in Google Analytics, right Facebook.

    So you see this grid supervised, unsupervised, continuous categorical.

    In each of these four categories, there are different types of techniques.

    So for when you know the outcome you’re after.

    And you have numbers, you can do regression and prediction.

    So regression, very straightforward mathematical operations and prediction very similar.

    That’s where you get things like gradient boosting, that’s where you get things like GBM, XG, boosts, even just go, good old fashioned, right linear regression.

    All that is to get to find to find the outcome you’re looking for, right? So you want to know, for example, what drives website traffic or what drives conversions, regression and prediction? Time Series forecasting is also in this bucket as well, because it’s a form of regression.

    When you have unsupervised machine learning and continuous data, you have clustering.

    So you have a bunch of numbers, how do they cluster together? How do they relate to each other? This is a great way to dig into things like, for example, SEO data, when you have a lot of SEO data.

    You have a lot of different numbers, domain authority, Link authority, inbound links, outbound links, number of words, etc.

    They’re all numbers, how do they relate to each other? You need to cluster it first to make start making sense of the data.

    And then only then would you then flip back over to regression say, Okay, now that I’ve made sense of the data, which of these clusters has a relationship to high search rankings.

    So clustering is is a very important set of techniques, we use it a lot.

    Classification and categorization and categorical, supervised, this is all speech recognition, image recognition, video recognition, this is classifying sentiment analysis, things like that anything that is non non numerical, you can be doing a ton of this classifying.

    Basie and learning and stuff is all in here.

    logistic regression is in here.

    And those of course, there are obvious applications, speech recognition, natural language processing, and so on and so forth, are all the classification bucket, and then Association and dimension reduction.

    That’s where you get a lot of natural language understanding.

    So trying to understand the words, the phrases the by grams, try grams in text, you see a lot of that, you see it in in the first stages of image recognition as well, before you go to classification, just trying to pick out the noise from the image.

    What’s foreground wants background.

    When you understand this framework of the types of machine learning, then you can start mapping it to those business outcomes.

    But you have to understand this first, if you don’t have this stuff down first, and understand the techniques that go in each of these buckets, it becomes very, very difficult to make sense of AI.

    Because what happens, of course, is that you it just gets too messy, right? And you don’t if you don’t have this in your head that you don’t how the underlying techniques that go in it.

    So in supervised you have for example, Oracle regression, random forest regression, boosted tree regression, linear regression, and unsupervised you have k means clustering, covariance clustering.

    For categorical stuff, you have decision trees, logistic regression, neural networks, nearest neighbor, I talked to I mentioned Basie, and early for Association dimension reduction, you have stuff like PCA LPA, CCA TSNE.

    But if you don’t understand these things, and you don’t understand the techniques inside of each of them, then it becomes very difficult to apply them correctly.

    So understand this stuff first, and the techniques within them, and then start thinking about Okay, now how do I apply this to business outcomes.

    If you don’t have the command of the techniques, then one of the content sequences of this is that it becomes very easy for vendors to for you, it becomes very, very easy for vendors to take advantage of to say, Oh, yeah, we use machine learning we use.

    Imagine a vendor saying we used advanced machine learning and proprietary dimension reduction techniques to predict the future? Well, no, you may do dimension reduction to clean up the data.

    But if you’re predicting using dimension reduction techniques, you’re literally doing things completely opposite of the way they should be.

    So this is it’s important for marketers to have this vocabulary.

    You don’t necessarily need to write the code, but you need to understand the techniques involved in order to map them to use cases.

    Once you understand the data each works with and the techniques in each then finding use cases for all the stuff is very, very straightforward.

    Not easy, but straightforward.

    So an important question because understand this stuff first and then go hunting for use cases for AI machine learning a lot to unpack your lot to study.

    I’m still learning.

    Everybody I know in the field is still learning.

    There’s new techniques being developed all the time or improvements to techniques, so keep that in mind.

  • You Ask, I Answer: Successes and Failures of AI in Marketing?

    You Ask, I Answer: Successes and Failures of AI in Marketing?

    Annika asks, “Can you give me some examples of digital Marketing projects that use AI in some way that failed and succeeded and reasons behind The success or failure?”

    Some of the most prominent failures are those in which people didn’t keep their eyes on the system after deployment. In marketing, that’s systems like sentiment analysis, which has a small raft of problems. Microsoft had its very visible Tay failure. Successes are legion and very tactical, along what we call the 5Us. Watch the video for full details.

    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, Monica asks, Can you give some examples of digital marketing projects that use AI in some way that failed and succeeded, and the reasons behind the successes and failures.

    Some of the the more prominent failures in the space of those in which people didn’t keep their eyes on the systems after deployment, one of the major faults, or reasons for failure and many AI projects is that after you deploy your model, you don’t keep tuning it, you don’t keep adjusting it in the model drifts, which means that it begins to behave unpredictably.

    It receives data that it doesn’t know what to do with or forecasts poorly.

    So that is sort of the root reason why many AI projects kind of go off the else.

    The most prominent example This was having Microsoft’s a Twitter chat bot.

    I think it was from 2017, which in which Microsoft deployed this chat bot on Twitter, and it was unsupervised.

    They wanted to see how it would interact with users.

    And within 24 hours, users had turned it into a racist porn bot.

    And that is a function of model drift, where they didn’t anticipate the the lesser aspects of human nature.

    And the model drifted and eventually became unusable.

    What they should have done that in that particular instance, is had a constant cycle of tuning a constant cycle of reinforcement learning with active learning, which means that a human should have been in the loop at all times.

    Continuing to tune the model and saying yeah, that you just got their reject that when Microsoft and IBM had it, some project debater AI, this past February, one of the 10 ai is under the hood was an ethics module that had, in addition to being trained on a bunch of what not to say, actually had some rules hard coded into it that it was never allowed to do to do was never, for example, allowed at any point to reference Hitler.

    So that is a really good example of one of the core things, one of the many, many things that can go wrong with any kind of AI is model drift.

    And if you want to read more about the ways AI projects failed, is actually a blog series I’m doing over we’re at the trust insights blog, you can see it there on ways AI projects fail.

    Another way that is very marketing specific, is that a lot of companies have done a relatively poor job with sentiment analysis, they tend to rely on very, very old approaches for sentiment analysis bag of words, approaches, you know, this word is generally bad.

    This word is generally good and of course, fails to take into account any kind of context.

    And the reason for that is not AI based in a lot of cases, that is just computational cost based.

    The the cost to do more advanced types of machine learning on language, in many cases outstrip what that company is able to spend and still be profitable from a compute perspective, or they don’t have the code and talent to implement modern sentiment analysis.

    In terms of successes in AI, in marketing, there are they are legion because many of them are very tactical, and address very solvable, manageable problems for marketing.

    Again, this isn’t that we call the five use untapped data, being able to use machine learning to classify and categorize unstructured data like call center calls, emails, etc, and be able to extract information classified very, very quickly.

    dimension reduction, which is a huge problem for most marketing data sets.

    They have many, many dimensions, many columns in the spreadsheet, if you will.

    And using techniques to do feature selection and dimension reduction, understand what’s really important.

    There are many, many examples of being be able to do driver analysis, multiple regression in which you are trying to figure out what is at the heart of a problem.

    So if you have all this data, say, posts on social media, and you have all the reactions likes, wow, and whatever in posts, views, and shares and comments, which one of those metrics or which combination of those metrics is really impactful? would be a an example of that.

    You have techniques like network graphic, which is the type of machine learning, being able to identify the relationships between entities very useful for sentiment and outlet for social media monitoring, for influencer analysis, very, very powerful stuff.

    And of course, you have predictive analytics time series forecasting, being able to forecast forward, when is a specific search term going to trend, and that that helps you then set your editorial calendar.

    So there are many, many tactical successes for using AI and machine learning in marketing? They are they are legion, I can refer you to a number of talks that we’ve done over again on the trust insights website, detailing this in much greater depth.

    But in terms of successes and failures, what sets apart successes and failures in AI and marketing more than anything else, this is something that my CEO constantly says is all about the planning.

    Do you have a clear business goal? Do you have a well defined approach? Have you done your technical requirements? Well, at the end of the day, when you’re doing AI, and you’re doing machine learning, the output is software.

    So if you are not treating it like a software development project, you’re setting yourself up to fail.

    On the other hand, if you follow decades long best practices for software development, knowing that you know a portion of the prod of the development will be done by a machine you will be much more likely to succeed.

    So those are some of the basic basics.

  • You Ask, I Answer: How to Analyze Business Data?

    You Ask, I Answer: How to Analyze Business Data?

    Andrea asks, “What is your go-to strategy to analyze your business data?”

    The exploratory data analysis process is a very straightforward, proven one:
    – Goal and strategy
    – Data collection
    – Attribute classification – dimensions and metrics, data types
    – Univariate analysis
    – Multivariate analysis
    – Data quality analysis – missing, NaN, inf, -inf
    – Anomaly and breakout analysis
    – Data requirement verification
    – Data preparation – centering, scaling, etc.
    – Feature extraction
    – Feature augmentation
    – Feature selection
    – Modeling
    – Other applications

    This process is one that you cannot shortcut if you you want a good outcome.

    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, Andrea asks, What is your go to strategy to analyze your business data? That strategy is generally the same.

    It’s a defined process, regardless of what kind of business data you’re looking at marketing data, sales, data, finance data, and so on and so forth.

    And it is a many, many, many step process that in the data science world is called exploratory data analysis.

    And what that means is exactly what it sounds like, explore the data to find out what’s in the box, like, what are the things that are in this data set that we need to know about in order to make decisions about its quality? Can we use this thing? Can is the data any good? and so on and so forth? So let’s look at those steps.

    Number one.

    What is your goal and strategy for the data? And this is specific to the the data itself? Do you have a data strategy around the state? Do you know what you’re going to use it for? Do you know why you have it? You know how you got it? That part is vital, because there’s this thing called lineage which is part of governance, that is essential for understanding where the data came from, and being able to in an audit document where you got it from, and and that it was, it maintains integrity throughout your pipeline.

    Second step, of course, is data collection got to get the data from somewhere.

    The third step is attribute classification.

    What have you got in the state of what are the dimensions? What are the metrics? What is the categorical continuous variables? And what are the data types? If you think about something like a sequel database, the sequel database can have many, many different types of data, variable character line fields, numeric fields, integers, floating point fields, can have binary fields, large text blocks.

    So what is what is the stuff right? What? What kind of data did you get? The next step is once you know what you have, doing what’s called unitary analysis, and that means when you’re doing basic statistics on the fields that you’ve gotten this data, so for numerical fields, what’s the average or the mean? What’s the median central tendency? first, second, third, core tiles? What are the the summaries of numeric fields for non numeric fields? What are the width of length of the fields? What are the types of fields that they are the number of counts, number of distinct entities, if you get a bunch of, for example, first names, how many times is the name Julie up here, within that, that field, so you have to do this university analysis and create and collect statistics about the different types of data that you have.

    You may also at this point, do some sorting, just to get some a rough sense of what are the most prominent features.

    The second step is multivariate analysis, where you start looking at relationships between fields.

    For example, you have first names, you have last names, you have certain first names go with certain last names, you have birth date, to the certain years, months, days that have relationships to certain types of names.

    So multivariate analysis, lets you understand the different types of relationships in a data set for something like, for example, commute, a consumer finance, you could look at, say complaints, what are the the the strength of the complaints? How long are they? And is there a relationship between the length of the complaint and the strength of the complaint to people who are angry or leave longer complaints, for example? So that’s a multivariate analysis.

    After that, you have to do data quality analysis, What’s missing? What’s what things that have errors? What things have values that are outside the bounds of what you would expect? Do you need to do any kind of data preparation? This will help you answer that question.

    After that comes anomaly in breakout analysis, which is, okay, say that they do have? Are there weird spikes in? Are there trends are there trends and changes, especially if there’s time involved a time series.

    So not only breakout detection, very important, then you get to a really important part, which is called Data requirement verification.

    In the golden strategy section, you set out what the data was for, why you have it, and how you’re going to use it.

    And where it came from.

    Data requirement verification, now you analyze the data set, you know what’s in the box, you have to very be very thorough in matching up, did we get what we needed? Or are there pieces missing are the pieces that do not meet the requirements of the project.

    And this is the part that men, many, many folks skip over, I have skipped over it in the past, and I have paid the price for it by not being able to do the work that I needed to do.

    So that’s super, super important.

    The next step is, if as long as you’ve met the requirements, and the date is in good condition, you’re going to do a whole bunch of data preparation.

    So centering and scaling the data if you need to removing anomalies, cleaning up the data essentially, after that, you do a step called feature extraction, where you pull out attributes from the data to make new types of data, especially if we’re going to be using this data for any kind of machine learning.

    And feature extraction is is making new fields from existing fields.

    So for example, if you have a date, that when a landline form is filled out, you can extract that the day of the week, the week of the month, the month of the year, the quarter of the year, and the day of the quarter, and so on so forth, you can create new features from that, because those features may be useful for modeling.

    At this point, you may also choose to do feature augmentation.

    feature augmentation occurs when you’ve done the requirements gathering, and you verified the data meets those requirements.

    But you know, through your own domain expertise, there might be additional data from third parties that could supplement I could add new things.

    Even though they’re not part of the original requirement, they could add value.

    So you may choose to use augmentation, again, that requires a lot of domain expertise.

    If you’re looking at, I don’t know, cardiac data.

    What are the things that as a cardiologist you wouldn’t you know, other data exists out there, someone like me, who is not a medical professional would not know how to do that, I would know that there might be other data out there.

    But it wouldn’t necessarily know what it is or where to go looking for it.

    The next step is features selection, great, you’ve made this huge data set with thousand columns, right, and you’ve extracted and augmented this thing.

    And it’s super huge and robust.

    Now, you need to remove anything irrelevant.

    So feature selection is what features are important.

    If you’re doing any kind of supervised learning or looking at trying to analyze the specific outcome, say, like, you know, customer value, or their features that simply have no mathematical relationship to customer value, if so, you can drop those.

    And finally, you would do either modeling or other applications of your data, where you’ve done the analysis, you understand this data left, right up, down.

    Now, what are you going to do with it? Are you going to take it right from this point as insights and, and or generate insights from it manually? Or you’re going to turn it over to machines for further analysis? What are you going to do with the data? So that’s the strategy for analyzing business data is extensive.

    It requires a lot of time, and it requires domain expertise.

    So this is not something that you can do quickly.

    Generally speaking, not if you want to do it well.

    And it’s not something that you can do cheaply.

    Again, not if you want to do it well.

    Now if this is data, you student Hello, making a ridiculous like Instagram meme out of you don’t have to spend, you know, months to do that.

    But if you’re going to be betting your business health, or your customers health or wealth on this data, you better do this exploratory data analysis process really, really well.

    And that takes time and money.

    So great question Andrea.

    complicated question.

    You have to do it as well as you possibly can within the limitations that you’re given for the data and for the overall business.

    If you have follow up questions, please leave in the comment box below.

  • You Ask, I Answer: Implementing Personalization at Scale?

    You Ask, I Answer: Implementing Personalization at Scale?

    Paroma asks, “How should marketers be implementing personalization at scale without diminishing the human connection?”

    Personalization is all about adding specific details to our marketing, from the most basic basics like getting someone’s name right to the most advanced techniques in AI, creating unique, individual content for everyone in a 1:1 way. Personalization is thus contingent on the quality of our data, in order to effectively personalize, the quality of our product or service – and our marketing is a product – and the quality of our content generation techniques.

    Most marketers don’t have access to the most powerful content generation techniques, not because they’re expensive, but because they’re incredibly technical. So, do the best you can with the data you have, and focus on improving the quality of your data and the overall quality of your marketing in preparation for content generation techniques to become more affordable and reachable.

    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 per oma asks, How should marketers be implementing personalization at scale without diminishing the human connection? Interesting question. personalization, at least as we currently have it in marketing is all about adding specifics to our marketing that are relevant to the person that’s receiving it on the other end. This is anything the most basic of basics like not putting Hello, first name, the beginning of our emails, all the way to the most advanced state of the art techniques in personalization to which are driven by artificial intelligence by machine learning by data science. And that is the creation of unique individual content for everyone in a one to one way that means when someone comes your website, they are seeing content that is only for them, and nobody else and and if five people all went to your website, all five would see different variations over time of that site that was tuned towards what they cared about based on their preferences. You see this today with things like YouTube, right? If you look at to people’s on their home computers or their phones, to people’s YouTube accounts, you can see very different recommended videos depending on those the person’s preferences. So we know that this personalization exists today, in email marketing, personalization, gets even more tricky, right? Because in the most advanced use case, you would have you’d be using individually tailored emails for every person not not Hello, first name. But what I get in my newsletter, the news, I get the articles, I get the content written for me, the featured things all that would be very different than the person may sitting right next to me, I they might get completely different stuff. You see this again, retail, Amazon is legendary for its ability to personalize to be able to create content that in email marketing, that nobody else gets, right you that is your Amazon reminder that you need to go and buy some more stuff from Jeff Bezos. So that’s where personalization is, there’s a broad spectrum from Hello, first name to this email is only for you. And it’s contingent on three things. So personalization is contingent first on the quality of our data. If all you have is just a single piece of information, like the first name and an email, there’s very limited personalization, you can do right, you can personalize only on that person’s name. Or if all you have is, you know, a single visit to your website, you can only personalize based on what you’ve got. So you need to be collecting data, you need to be storing data, you need to be analyzing data really, really well. The second care contingency for personalization is the quality of the product or service, including the marketing of it, because marketing is a product. What what are you offering a value, I would submit that personalization is less important than quality of your marketing. Right? You can personalize crap, right? personalized, I can write a script that will personalize word salad and email it to you it will be personal, it will be tailored to you. It will be valueless. I would rather get a generic email that provides a lot of value to me, then then personalized garbage. And the third is the access that we have, or the quality we have of our content generation techniques. And this is this is a test a logical question. most marketers today do not have access to the most powerful artificial intelligence content generation techniques. And it’s not because they’re expensive, actually, some of the most advanced techniques are totally free of financial cost. But there is an incredibly high technical barrier. That technical barrier requires you to be able to do data science to fine tune, neural network models do all sorts of crazy stuff with the technology. And so it’s out of reach is out of reach. And there are not a ton of vendors yet that are putting it within reach. There are some that are coming. Stay tuned as I as I record this year in the middle of 2019. I expect by the end of the year for at least a couple of vendors, one of which I informally advise and consult with Penn to really have incredible service offerings. What sort of thing is scum, warrior boy your mind way?

    But it’s not yet. And that will be cheap to start. So what should a marketer be doing? What should you be doing? Number one, do the best you can with the data you have. Right? That is fairly obvious. But again, it’s it’s untapped. A lot of people don’t do that. improve the quality of the data that you’re collecting. Right. So not just more data, but better data. Not just simple stuff like demographic or firma graphic or psychographic or techno graphic data with behavioral data, behaviors, what’s going to set your personalization apart. Somebody who visits certain pages on your website is going to show a certain type of intent, especially if you’ve got more than one product. So you want to focus on what what are they looking at? Right? What are they doing? And what do you have that maps to that that you can create algorithms and code and content for them based on their behavior. Focus on the improving the overall quality of your marketing to write because, again, no one wants personalized garbage even if it’s really sophisticated garbage. Still garbage, right. So make sure that your marketing is of a high enough quality that somebody would actually want it. Because Jay Baer, who said a number of years ago, that, you know your marketing is at the top of its game, when someone is willing to pay for it. When someone not not for your product, but someone’s willing to pay for your marketing. That is when you know you have reached the pinnacle of marketing power. And so that’s your benchmark, are you creating marketing that’s so good, so good that somebody would pay for it. And then finally, of course, Bob focusing on your marketing quality by focusing on the collecting data, you are laying the groundwork for those artificial intelligence content generation techniques. As they as they do become more affordable as they do become more in reach for organizations of all size. That will help you’ll be ready for it, you’ll be prepared for the advent of it, I would suggest taking some courses on data science and machine learning and artificial intelligence. If you go to cognitive class.ai, which is IBM free Academy for data science and machine learning. There’s a tremendous amount of great content totally free of cost zero dollars that you should take. And you can earn badges and certificates and continuing education stuff and all that good stuff. But the skills that you need to make this technology work are in the course were there and again, it’s free of cost zero dollars. Of course IBM is going to lead you towards using their platforms and things. That’s logical, but there’s a lot of open source stuff, pilot on our panda socket, learn all that stuff is in there. So make use of those resources. They are free financial costs, they only require your time. So good question from improve your data quality, improve your content quality, laid the foundation for great individualized content generation as the techniques become available.

    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 we are reviewing the IBM Watson studio new feature called auto AI or auto automated artificial intelligence. Now, before we begin full FTC disclosure is my company trust insights is an IBM registered business partner. We receive compensation for any purchases you make from IBM through US and US I receive indirect financial benefits. So FTC closures disclosures out of the way, auto AI is a type of automated machine learning which promises to help companies get to working artificial intelligence models faster given the data set, instead of the time it takes to go from data cleaning, prep, feature engineering, hyper parameter, optimization, model experimentation, and then to production that can depending on your data set, take a really long time.

    By the way, I promises to help companies do that in less time. Now, before we begin, there are both features and disadvantages of this approach. There is even though it can be very manual and tedious, there is some benefit. I’ve actually personally, there’s a ton of benefit to manually editing and cleaning your data set of

    and doing the feature engineering because it helps you get to know your data. And so if it’s something as mission critical, at least the first time through, you want to have a human do that after that, absolutely use automated machine learning. And one of the questions that people have had over over the last few months is, you know, will this replace data scientists know, and we’ll talk a bit more about that. But it’s not going to replace data scientists anytime soon. It will help data scientists workload get a little bit easier for the most common types of machine learning models. So let’s get into the environment.

    What we see here is Watson studio, and I’m going to fire up a an auto AI experiment. And we’ll do we’ll call this something auto test something. They’re really exciting.

    And our first experiment where you see here, you can add in testing data that we are adding training and data I’m going to throw in, let’s, let’s do some Google Analytics data, right? Google Analytics data is a rich source of information. And it’s something that a lot of marketers have access to. So this is going to be things like users and sessions and balances, and I have goal completion. So that’s what I want.

    All the way I’d help me do is help me understand, maybe a little bit better. What gets goal completions for my Google Analytics data?

    See, I dropped the data set in and asked me what do you want to predict? What do you want to know more about Of course, I want to know more about goal completions. Now here’s a bit of a landmine in this because

    Of the Way goal completions are structured is data set by pages, you know, one or two goals per page. So, auto a, I said, Hey, I think you’re trying to do a multi class classification. I’m actually not. This is again, why you can’t fully replace the data scientists with these software packages, because this is not a classification problem. This is a regression problem.

    So choose that I can choose the error metric, which again, if you are a data scientist, these mean a lot to you, if you’re not a data scientist, just go with whatever is recommended.

    But

    this is a case where that was not the correct prediction type. So it’s going to run the experiment. And what you’ll see next is if the entire pipeline of what Watson is going to do with this data, it’s going to read it, it’s going to split it into three pieces. Generally speaking, when you’re doing model testing for AI you’re going to do you’re going to split your data into three pieces. 60% of it

    Going to give them machine it’s going to try and learn from that and figure out, oh, well, this is your date, I’m going to try and learn what the patterns are, there’s 20% of it is going to be called test data. So once the machine first figures out, okay, I think this and this lead to conversions, it’s going to take the next 20% of the data set and test that, that conclusion out, see if that is is is true or not. And then there’s a third 20%, where it’s going to test the testing of the conclusion. This way, you avoid or you reduce the likelihood of what is called overfitting, where you make a prediction, that’s perfect. But then, when new data comes in, it goes off the rails. So it’s a split the holdout data, read the training data, do its own attempt at cleaning the data as best as it can.

    None of the automated machine learning tools, zero of them on the market, do a really good job of cleaning data perfectly. Right? That’s still the data that goes in still

    has to be good. And if it’s not good and it’s not in good shape models will simply not work. And this is true of Google auto ml. This is true of h2o Auto Mel This is true of IBM auto AI, it doesn’t matter whose system you’re using garbage in, garbage out, that’s going to be the truth forever just garbage. So, it then goes and chooses a model what kind of machine learning model would best fit this data?

    We see here it is chosen x g boost regressive. So extra boost is one of those popular algorithms that can help find

    what is likely causing regression or what it runs a regression model x g boost,

    which stands for extreme gradient boosting is probably the the most popular machine learning model for doing any kind of regression to one a bunch of cackle competitions and it’s just one in the toolkit. Now this is where auto AI has some real benefit for

    People who are trying to learn data science, I think this is a fantastic learning tool because you can see the choices it makes. And if you’re not familiar with the choice, and you go look it up and read up on it, but if you see the choice that makes any figure, okay, that’s an interesting choice. Why did it choose that? As it’s going through, you can see here on the on the bottom, as it makes each pipeline of learning, it tells you why it made those choices. So ranking based on the error that click on this pipeline data, you can see how it evaluated the model, the R squared error model information and the feature importance what it thinks is most likely to predict goal completions. And now it’s going to go through a few stages of really the the machine learning experimentation the exploratory process. So the first thing is to is hyper parameter optimize optimization.

    Hyper parameter optimization is you

    Really, really fancy way of saying it’s going to play with the settings. So an extra boost algorithm has a bunch of settings. It’s like It’s like an app on your phone. Right? An app on your phone has settings, you can make this you know the the app louder, we can turn off notifications or stuff.

    A machine learning model is a piece of software. And therefore what it’s doing now is it’s testing it’s running simulations to test. Okay, what if I turn the brightness up on this

    an extra boost to be like, How many? How many runs? Am I going to do? How many times Am I going to try this thing? How many different splits the data we’re going to make? Out of the box? You know, there are certain defaults in that and then what the software is doing is testing all of the defaults to see, do we get better error rates out of this test based on trying out different settings, once it does hyper parameter optimization is going to do feature engineering. And this is where

    I’ve given this feedback to IBM, I think there’s a little bit of a bit of a misnomer. It does feature extraction. feature engineering is a five part process, right? So you have things like extraction, where it’s going to try and create new features from the existing data, which is exactly what this does. By doing things like multiplying columns together or dividing columns or adding or subtracting. There’s a part of feature engineering that called feature creation that we bring in net new data from the outside, it does not do that. So there’s only a limited type of feature engineering. And then it does another round of now that’s got more data to work with because it’s created these imputed columns to do another round of hyper parameter optimization. Now this will take probably 10 or 15 minutes, so we’re just going to pause here and and let it do its thing and come back when it’s finished baking.

    We’re back it’s been a little more than an hour.

    And what we can see here is that Watson has gone through and created four different machine learning pipelines, one with just a straight x g boost algorithm, one with some hyper parameter optimization, that tuning of all the knobs and dials on the different extra boost models. One with feature engineering done, and one with a second round of hyper parameter optimization after the feature engineering is done. So let’s take a look at see what what we see here we have four different pipelines. And with each of the enhancements, there’s the straight, I just analyze the data that you gave me and built a model on it. And then we see pipelines three and four have identical outcomes. The same route means squared error rate. One has feature engineering and hyper parameter optimization one has both. Let’s take a look at pipeline forces has the most number of things that have happened to it. We’ve got a small r squared. We’ve got the model information. We have a whole bunch of feature training

    formations that have happened. You see it through here, there’s all these PCA that stands for

    principal component analysis. It’s a way of reducing the number of total features because it means essentially, there’s too many for the machine to find a good conclusion from. And then of course, additional engineered features users, the difference free users and sessions and so on and so forth. So let’s go back and look at compare now at the quote number one model, which is pipeline three

    yc pipeline three has the about the same art actually does have identical r squared,

    same feature transformations

    as the previous one.

    And here it’s saying that new feature to which is the difference between users and entrances is the most important feature as moderately important with the score of point 31. for determining what, what drives or what predicts goal completions.

    My Google Analytics data now if we were to look at let’s in fact look at what this similar setup would look like in a different programming language. This is a the language are and you can see in h2o which is the auto machine automated machine learning model that runs inside of our one of many do the exact same thing. There’s your your training the split data, there’s your testing this you’re running your models, then there’s the leaderboard with comparison of the different types of outcomes came up with and its outcome, which was averaged one page sessions and average session duration. Know what’s missing here. None of the hyper parameter optimization or the feature engineering has been done on this The h2o is auto ml literally just takes what you give it and it does its best, but it doesn’t do any of those extra steps. So what do you do with this right? You’ve got this thing what now what what what happens? You save this as a model

    Inside your, your Watson studio environment and then you deploy the model using Watson machine learning that gives you a an API connection that you can then send additional data into this for and have the it score and predict like yes, will this convert or no will this not convert. And from that information, you would then build software, maybe build a special chatbot on your website that only pops up when certain conditions have been met, the ones that we see here, in in these models, maybe you use this to change your marketing strategy, if you know that the difference between users and Sessions is important in this model, maybe you use that information to figure out what kind of user what kind of

    or what type what kind of

    person or session is happening on your website, that you can then build additional features on your website, maybe different copy depending on what you can come up with.

    So this is a useful tool for getting that model into into production. And being able to make use of it being able to, to hop, operationalize a lot of a lot of these insights.

    There are still gaps. There are still things that I personally would have done differently.

    But there are also things he has like, Huh, I never thought about doing that. So this is not only a good tool for getting your model into production, but also for learning from it and going okay, well, maybe, maybe I need to think differently about the types of data I include, we see that Watson is doing a lot of these mathematical operations on different variables. Okay, what if we include more variables? What if we include different variables? What if we pull more data out of Google Analytics or your Salesforce CRM or your HubSpot instance, or your social media monitoring tools doesn’t matter what but putting more data in will let the model have

    More to work with now.

    As you said at the beginning, this does not in any way replace a data scientist, there are still gotchas, there are still things that it can’t do within this, this framework there even still things that from a, a modeling perspective may not be the best choice of what’s available. For example, if you want to determine what drives conversions, there’s a particular model that I use a lot for trust insights customers called Markov chains. It’s not available in here. It’s not available in here and it’s something you have to build by hand. And that is a better way of doing attribution analysis. But this is not bad. But there are limitations to what auto AI can do. So

    takeaways.

    One, regression classification built right in no code. This is that’s a I think an important thing.

    Does those basic data science has like feature extraction or hyper parameter optimization? I think those features are really useful for someone who’s learning data science. Someone who knows what kind of general outcome they want, they just want the machine to go through and build it quickly.

    some disadvantages, obviously, you’re limited in the number of models. Watson auto way I can choose from there are limitations. Your data has to be good going in. You can you’ve seen here, even though it doesn’t feature engineering, it doesn’t preparation, it does not validate. Wow, this is really dumb data. Right? For example, at no point did it say, you know,

    those are not the columns, Google Analytics, I would choose. The system simply doesn’t know that doesn’t have the domain expertise. You still have to provide that domain expertise, you still have to provide those insights. And the last thing, which I know according to the team, is coming at some point is the ability to go back and tune the model at any

    In a more granular way, it’s not available in the platform yet. So

    should you use this? It’s worth a try, especially since you can try it for free. If you go to IBM data platform data platform, cloud, IBM com, sign up for a free account, try it out, test it, see how it works. There are other features within Watson studio, you can also test out and try out.

    Am I going to use this to replace all the work that I do trust insights? No.

    But am I going to use this situationally as another tool in the toolkit? Absolutely. It’s one of those things that is worth doing, even if just to validate my own models to be able to look at it like when I’m looking at my, this auto ml model is did i do enough to engineer the data? The answer in this case? Probably not. Right? There are some more things that even I can learn from an add new features to the data sets that I already work with. So if you’re learning data science and

    A great tool, if you know what you’re doing great tool. If you want to learn this great tool, give it a try doesn’t cost anything to get started. And again, back to FTC disclosure, we are an IBM registered business partner. So if you’d buy something from IBM through us, we do gain. We do have financial benefit.

    You Ask, I Answer: Marketing Skillsets to Hire For in an AI Age?

    Denis asks, “Are there new skillsets that marketing leadership should be hiring based on the impact of AI will have?”

    The answer to this question is contingent on the types of AI solutions your company will be deploying. Broadly speaking, you’ll be needing to identify efficiencies for AI to automate, increasing complex human work like true innovation, leadership, domain expertise, and creativity, and inspecting and tuning the outcomes of AI.

    The skillsets required would include strong data analysis capabilities, machine learning expertise, and the soft skills around innovation, leadership, domain expertise, and creativity. The latter will be the hardest, because it requires experienced recruiters and HR staff, as well as hiring managers, to be able to understand innovation and creativity.

    What you won’t be hiring for are repetitive tasks and repetitive work. If it’s repetitive, AI will do it, so those roles will be smaller in number.

    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, Dennis asks, Are there new skill sets that marketing leadership shouldn’t be hiring for, based on the impact that AI will have? Yes, the answer to this question is contingent on the types of AI that your company will be deploying. For example, if you’re just going to do something very limited, like, I don’t know, put up a chat bot, then you might want somebody who has a natural language processing experience. For example, if you’re going to be building your own chatbot, from scratch, but broadly speaking, you’re going to need to identify the efficiencies for AI to automate. So that’s going to be one type of person you’re going to want to be able to hire. Those are people who are good at process management, project management, Product Manager, management, Business Process automation, and about whole soup of acronyms that goes with that total quality management, Six Sigma, you name it, that’s, that’s going to be one bucket of people, people who can help you decide what problems you want to solve with artificial intelligence. The second group of people you’re going to need are people who can help you increase the quality and the quantity of complex human work. So that will be things like interpersonal relationship management, true innovation, people who can actually innovate, there are, there are a lot of people who use the word innovative, very few people who actually are very few people who can create something new, that didn’t exist before. Another area where you will need more people rather than less is going to be around leadership. Again, there are a lot of people who claim the word leader, there are not a very many people who actually are leaders. And of course, creativity. This is an area where you will need more people who are truly an actually creative. Again, a lot of people use the word, not a lot of people can do it. The third group of people you’re going to need are people who can inspect and tune the outcomes of AI, it will be sometime before AI can be just given a pile of data and and come up with good answers that require relatively little to no cleaning up front, or improving on the backend iterating improving on the backend. In fact, there’s an entire branch of AI right now called active learning, which has a human in the loop sooner. So for example, if you’re trying to classify customer service inquiries, and the machine knows it can do I was a positive inquiry that was a negative or unhappy inquiry. And then there’s probabilities between those those two ranges. Active Learning allows the machine to raise his hand soon and say, Hey, I don’t know what to do with this one. This might be sarcasm, it might be might be someone who’s happy and unhappy at the same time, what do I do? And so active learning involves people with subject matter expertise to help to and the machine. That is probably the last area I would say in one that encompasses or stretches across all these, which is domain expertise. There is going to be a tremendous call for people with greater and greater domain expertise in their industries. What do you know about your industry where the tips, the tricks, the hidden things, if you’ve got, you know, a little more gray hair rather than less? What have you learned that can be used to help tune and codify the results that people are getting? That is so powerful, and so absent? And a lot of machine learning work? A lot of the problems that we see happening with AI and machine learning right now is you have statisticians who can build a theoretical model, you have coders who can turn into code. But in a lot of cases, there isn’t someone of domain expertise to Satan. That’s not how that works. A real simple example would be, you could have somebody say in food science. And the coders, the statisticians are saying, well, these foods clustered together most of these.

    And the coders codify that and no one’s saying, folks, you got to put, you always got to put salt on tomatoes. Because the food science person, the food expert knows that tomatoes contain a natural form of glue tannic acid, which when you add salt to it forms a, a natural, MSG is right tomatoes always tastes better with salt. But a coder and a statistician would not know that only a domain expert would know that. So that’s an example where you need people who have domain expertise, whatever it is, your company does, to provide those little tweaks that make things so much better. Now, in terms of skill sets, you’re hiring for strong data analysis capabilities across the board, that is going to be required for pretty much everyone, as time goes on being able to look at a data file that goes into a machine or look at the machines output and say, yes, that’s good, or no, that’s not good. Machine learning expertise, you’ll be hiring for some of that people who can tune the machines built them. Not everyone has to do that. But you do need a few people who can really get under the hood and make this the systems and software work. And then again, you’re going to be hiring for innovation, for leadership, for creativity, and for domain expertise. This last category, those soft skills, for the most part, and domain expertise is more of a hard skill. It’s going to be so hard. That’s the part where you will make or break your company your outcomes. Because as someone who used to be a recruiter, having someone used to be a hiring manager, identifying skills like innovation, and leadership and creativity are extremely difficult. Everyone says they are. How do you test for that? How do you discern that how to even test for whether a person is going to be a good fit into your company. One, one hiring trick I remember from the old days was to ask somebody describe their accomplishments of their last company. And if if they use words that were almost exclusively about that, well, I did this and I did this and I had a team, but I did this, that person’s probably not a good team player. Right? As opposed to, I did this and I work with the team. And here’s how I supported the team. Or here’s how the team supported me, or in this result is this was a group effort. And here is my role in this. This Africa, here’s what I did to help this effort come to fruition, but understanding that there was a lot more to what that effort was than just what the just what the one person the individual contributor did. Now, the one thing you won’t be hiring for repetitive tasks, and roles that are largely repetitive, if it is repetitive a machine is going to do it. And what you’ll see happen is those tasks will go away first. And then as those tasks go away, you will see the number of people needed in that role to get smaller and smaller. So for example, I used to work in the public relations industry. And there was one type of role that was largest copying and pasting all day long, that’s going away, right, that role is not needed in any capacity. Because the machine can do that you don’t even need to do that. You can just use regular programming to take that work and make it better and faster and cheaper with machinery. So look at the roles in your organization, if is 7585 95% repetitive work, that the tasks that role will do will will go to machines. And then the role will simply consolidate and diminish and eventually for some roles absolutely will go away. If someone’s job, for example, is literally nothing more than getting coffee for somebody else. That role is probably going to go away because as companies get more productive and get better at measuring productivity, they’ll see that that’s not generating business impact. So lots to unpack here about the skill sets that marketing leadership should be looking for, but it really boils down to data capabilities, soft skills, and domain expertise.

  • You Ask, I Answer: How to Use AI for Customer Service?

    You Ask, I Answer: How to Use AI for Customer Service?

    Amy asks, “How can we use AI to improve customer service? What are some ways to practically implement it?”

    Customer service is everything from the purchase onwards in the customer journey, and companies are faced with dual mandates: make service better, but make service cheaper. What are some practical applications of AI? The keys will be around the two fundamental types of problems AI solves best: understanding and predicting.

    Understand:
    – What customers are saying to you, especially in non-text channels (but also text, like mining your CRM)
    – What customers to each other, from social conversation to search intent
    – What the profile of our MVCs is

    From our understanding, we will predict:
    – What customers will be high need vs. low need, and positive vs. negative
    – What customers will have the highest lifetime value
    – When customer needs will be highest

    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, Amy asks, How can we use AI to improve customer service? What are some ways to practically implemented customer service? Let’s start by defining that customer service is everything from the purchase moment onwards. So from the moment the purchase, the customer gives their credit card says, this is the thing that I want b2b, b2c doesn’t matter. And everything after that in the customer journey is customer service. So that means ownership, which is things like warranty and service and support to loyalty, which is and retention, which is all about making sure that the your your product or service still continues to deliver value to the customer. And ideally, ideally, value continues to increase longer the customer own something. And of course, evangelism, helping the customer if they’re happy to talk about owning the product or service and looking for people who are having those conversations already. So those are the things that we’re going to lump under customer service. Companies traditionally have had dual mandates when it comes to customer service and not necessarily good ones, the dual mandates are of course makes service better. But in a lot of cases, companies have been tasked with making service cheaper, because corporations see it as a cost center rather than a value center. Now as models of attribution analysis get better. We’re starting to see people thinking about customer service as a driver of up sells, for example, particularly in b2b if a customer is happy, they’ll buy more from you are FM analysis and techniques like that help with that. But there are still a lot of companies are stuck in the old mindset of sort of customer services, just a cost, keep the cost is low as possible, instead of making the customer deliriously happy. And they’ll buy more and recommend more. So what are some practical applications of artificial intelligence in this space? The key to the application of AI and machine learning and specific revolves around the two fundamental tasks that they would be tackling which is understanding and predicting to understand we would use machine learning to dig into things like what our customers saying about us, especially in in social conversations, and then search intent. For example, if I am an owner of a whirlpool washing machine, and I’m looking up a whirlpool warranty or Whirlpool, whatever error code, guess what, I have some service issues, right, I have some support issues that I need to have resolved. If I own CRM software, I’m looking for the for how to do a certain thing. Sir, type that into Google, I would want as if I was the company, I would want to be using machine learning to analyze the data and understand relationships between different types of searches, relationships between searches and social conversations, at what point does somebody stop searching and start complaining? Those are all things that I wouldn’t want to know. I would want to know what are the profile of our most valuable customer is what using techniques like clustering, categorization, dimension reduction, what are those, the the aspects or the variables of a most valuable customer, and that goes way beyond traditional RF m analysis. Traditional our FM analysis just looks at you know, recency of purchase frequency of purchase monetary value of purchases, and that’s okay. But if you have the ability, with machine learning to look at 100, 200, 300 dimensions of the customer, their demographics, the psycho graphics firma graphics, and you can then put together a real comprehensive picture that customer you should. And most of all, this is where machine learning is a shining beacon customer service, it is understanding what customers are saying to our companies, especially in non tech channels, I did a project recently, for a company where they said a 17,000 recorded calls in an audio format from their call center. And we had a I transcribed them and then had AI, digest that down to understand what are the key issues that these customers were calling about. But you don’t have to use advanced stuff like that. Even just mining, the data within your CRM is so valuable, and companies don’t do it. What’s in your customer service inbox, customers, companies just don’t look at that. And you can use AI to understand

    once you understand, then you can predict things the kinds of things you want to predict, for example, would be what customers are high need versus low need. If you have to reduce costs and customer service, you definitely want to know hire low need and who is high and low value, right? So what are the types of if a customer is high need and low value, and you have the ability to predict that type of customer, you can say let’s not market to those people versus low need high value let’s market to those people as much as we can use machine learning to isolate, understand and build a model for predicting that based on

    characteristics of data that you get, you can predict what customers have the highest lifetime value.

    Again, if you go beyond our FM and your understanding, and then build a models who predict this customer matches 42 of the 46 high value indicators, let’s make sure that, you know we we target them really, really cleverly and smartly so that we win their business. And finally, now what are the what are the types of sentiment in conversations? And can you create a model of cases that were resolved successfully versus cases is that we’re not resolved successfully? If there are things like sentiment and tone in conversations that people are having with the chat bot with the operator with the customer service forms? Can you predict when something’s going to go off the rails and intercept that early on, so that you that that person never gets to the stage where they cause a PR incident for example. So those are understanding predict the two basic use cases for machine learning and AI that will help customer service get better. You can do this with the data you have today. What you have may be messy, it may need to be structured and cleaned up and engineered but the beauty is most companies have been collecting this data. It’s in your customer service inbox is in your CRM, it’s in your call center. You just haven’t been using it if you’d like help course I company trust insights will be happy to help with that.

  • You Ask, I Answer: Unintentional Bias in Data Science and ML?

    You Ask, I Answer: Unintentional Bias in Data Science and ML?

    Chacha asks, “Is there such a thing as unintentional bias?”

    This is an interesting question. Bias itself is a neutral concept – it simply means our data leans in one direction or another. Sometimes that’s a positive – there’s a definite bias of people in my Slack group, Analytics for Marketers, towards people who love analytics and data. Other times, bias is a negative, such as redlining, the practice of willfully excluding certain populations from your business based on broad characteristics like race, religion, or sexual orientation. In machine learning in particular, there’s tons of unintended bias, bias that occurs when we don’t give our machines strict enough guidelines about what we want our models to do or not do.

    Unintended means it wasn’t part of our design, part of a conscious choice on our part. There will be bias; the question is, what is its impact, and do we then keep it or disregard it?

    Most bias can be mitigated at either the feature engineering stage or the model backtesting stage if we know to look for it. The greater question is, are we looking for it? This is where the science in data science comes into play.

    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 tchotchke asks, Is there such a thing as unintentional bias? This is an interesting question. Yes, there is. bias is itself sort of a neutral. A moral concept me has no moral basis period. It simply means that our data leans in one direction or another. It has a skew or a a deviancy off this the central tendency, sometimes that’s a positive. For example, there’s a definite bias in my slack group analytics for marketers towards people who like analytics and data, right? That would make logical sense and that bias is intentional, and unintended, unintentional bias, and that is that statistically, if I look at the number of people who are in the group and their inferred gender, it leans female, that was unintentional. At no point did I are the trusted Insights Team say we want to focus just on this particular expressed gender. Other times, bias is a negative, such as the practice of redlining of practice, from the dating all the way back to the 1930s, when banking and insurance companies took out a map and drew red lines around certain parts of cities where they didn’t want to do business with people in those in those parts of the city based on broad characteristics, like race, or religion, or sexual orientation. And those that, again, is unintentional bias when you do the red lining, but there is plenty of unintentional bias where you say, I want to isolate, maybe people who have a lower income from my marketing. But that has comes with a whole bunch of socio economic characteristics, which do include things like race and religion and sexual orientation. So that would be unintentional bias. in machine learning. In particular, there’s a ton of unintended bias bias that occurs when we are not thoughtful enough about the choices we make in our data. And we when we don’t give our machines strict enough guidelines about what we want our models to do or not do. A key part of data science and machine learning today is asking yourself throughout the process, what are the ways that this can go wrong? is a very popular subreddit called what could go wrong? It’s a, you know, silly videos and stuff. But that key question is one that not enough people ask all the time, and then marketing, what could go wrong? If I build a list that is is cold from these data sources? What could go wrong? What What could go wrong in that data? What could go wrong in that analysis? What could go wrong in those insights? What could go wrong in our strategy? That is something that we’re not thinking about enough. Remember, the unintended bias means it wasn’t part of our design, it wasn’t part of a conscious choice that we made on our part, there’s always going to be a bias in our data sets. The questions that we have to ask our Is this a conscious decision we’re making? And if so, is it legal? What is the impact of an unintended bias? If we do discover one? And then assuming that it is legal and ethical? Do we keep it or disregard it? So again, if I see a bias towards a certain gender in my email list? What is the impact? Do we keep it? Do we disregard it? What are those things that that matter? The other thing we have to consider is that most bias can be mitigated, not eliminated, but it can be mitigated, the impact can be reduced. At a couple of different points in the machine learning pipeline in our data science pipeline, one is at the feature engineering stage. And when we are deciding what characteristics to keep or exclude from our data, we have to make decisions about if there’s a bias there, should we keep it or not?

    There is a I’ve heard some less skilled machine learning practitioners say, Oh, well, if, if gender is a concern, then we just delete that column. And then the machine can’t create features from that characteristic. And that’s a really bad thing to do. Because by taking gender out of your training data, then allows the machine to create inferred variables, which can be functionally the equation agenda, but you can’t see them. Right, if you know, if you have, for example, all the likes of somebody on Facebook, they know the movies, the books, the music, that they like, guess what, your machine can very easily create infer gender, and ethnicity and different sexual orientation with a high degree of accuracy. So instead, the best practices becoming, keeping those characteristics which the law deems is protected, and telling machines, these are the acceptable parameters from which the model may not deviate. For example, if you have, let’s say, you’re doing, I don’t know ROI on on your data set, and your and your machine spits out and says hey, the ROI of a certain religion is higher or lower, based on on that person’s religion, you can specify to the machine that people who are no Rastafarians must have the same outcome must be treated the same as people who identify as I know, pasta, Aryans, right. And so you can you can tell the machine, you must know this characteristic exists. And then you must treat it equally, he must not give a different outcome to somebody based on a protected class. So that’s an important part of that. So feature engineering is one of those stages where we can decide what key features to keep, and then mitigate bias within them. And this software like IBM is open scale that can actually you can declare those classes and say, you may not deviate from Express set out guard rails on your model. And the second is on that model back testing stage, where you are testing out your code to see what results that spits out. And that’s when you as a human have to QA the code and say, it looks like there’s a bias here, it looks like there’s a bias here, it looks like there’s a bias here, we can keep that one, we can’t keep that one. But you’ve got to be looking for it. And that’s where data science and statistics really come into play. And where a lot of folks who are new to machine learning and maybe talk about that crash course in in machine learning thing. Can they come up more coders than they do? still having a statistical background? As a result, they’re not thinking asked how could this data be misused? How could this data go wrong? How could we create unintentional biases that we then have to deal with later on? So there absolutely is such a thing as unintentional bias. And frankly, most of the time for most people in most situations, most bias is unintentional. We just have to know for it. Note note to look for it, ask how could this go wrong? And then mitigate it either and feature engineering model back testing. And this is something that marketers in particular have to be very careful about because marketers have a lot of personally identifiable information. And marketers tend not to be trained in statistics and data science to be looking for these biases. So when we use marketing automation tools to help us optimize our marketing, we also have to be asking, Are these tools creating biases behind the scenes that we do or do not want? So something to keep in mind there? Great question. important question. And if you want to learn more about the ethics side of this, I recommend picking up the free copy of Dr. Hillary Mason and Michael Keaton his book called ethics and data science. You can find it on Amazon as part of Kindle Unlimited, and I believe it’s zero dollar cost too. So make sure you pick up a copy of that book. It’s a really, really important read if you’re doing any kind of work with personally identifiable information.

  • You Ask, I Answer: Will Automated Machine Learning Make Data Scientists Obsolete?

    You Ask, I Answer: Will Automated Machine Learning Make Data Scientists Obsolete?

    Sheedeh asks, “Will new advances like automated machine learning make data scientists obsolete?”

    Most definitely not, though I can understand why that’s a concern. AI is currently automating a fair number of tasks that data scientists do, but those tasks are relatively low value. I’ve had a chance to test out a bunch of automated machine learning frameworks like IBM’s AutoAI and H2O’s AutoML. The new features are time savers for data scientists, but cannot do what data scientists do. One of the key areas where automated machine learning is, and for the foreseeable future, will fall short is around feature engineering. Watch the video for full details.

    Recall that there are 5 key types of feature engineering:

    • Feature extraction – machines can easily do stuff like one-hot encoding or transforming existing variables
    • Feature estimation and selection – machines very easily do variable/predictor importance
    • Feature correction – fixing anomalies and errors which machines can partly do, but may not recognize all the errors (especially bias!)
    • Feature creation – the addition of net new data to the dataset – is still largely a creative task
    • Feature imputation – is knowing what’s missing from a dataset and is far, far away from automation

    The last two are nearly impossible for automated machine learning to accomplish. They require vast domain knowledge to accomplish. Will automated machine learning be able to do it? Maybe. But not in a timeline that’s easily foreseen.

    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 she asks Will new advances like automated machine learning, make data scientists obsolete? Most definitely not. Though, I can understand why that would be a concern because obviously, automated machine learning makes many promises like it’ll speed up your your AI pipeline, it will make your company faster, data scientists are expensive, and so on, so forth. But a lot of the promises that they’re being marketed about AI, automated AI are falling really short. AI is and should be automating a fair number of tasks that data scientists do. But those tasks are the low value. And one hot encoding a table is a low value task from the perspective of if you’re paying 300, 400 $500,000 a year for this person, having them encode a table is something that a machine should definitely do, it’s not the best use of the time. And a lot of these newer automated frameworks, make the promise that they’ll handle everything for you, you just put in the data and magic happens. I’ve had a chance to test out a bunch of these frameworks. These automated machine learning frameworks, IBM is auto AI, h2o is auto ml remixes auto ml. And the features that are in these toolkits are time savers, for sure, for data scientists, but they can’t replace a data scientist. They can augment they can reduce some of the repetitive tasks, the low value stuff, but they’re not a replacement for the person. I’ll give you an example one of the key areas where automated machine learning really falls short. And will for the foreseeable future is around feature engineering. feature engineering is a fancy term in data science for essentially, college in a table, right, so if you have a spreadsheet, it’s the columns in your spreadsheet. And there’s five key types of feature engineering, some machines can do, well, some can’t. As an example, let’s let’s imagine a table with four features, right? The date that you brewed a cup of coffee, the temperature of the coffee, what being type used, you know, Colombian or Nicaraguan whatever, and an outcome was a good cup of coffee or not. And you want to know what makes for a good cup of coffee, we’ve got a table with four features, it’s not a whole lot of data to build a model on feature engineering is all about creating and updating and tuning your data so that you can build a better model. And that model can then be used to predict whether the next cup of coffee you’re about to brew is going to be good or not. Right. So we have date, temperature being variety, and outcome was it a good couple. So the five areas of feature engineering, number one is extraction. This is where machines really shine easy to do. If you have the date that you brewed a cup of coffee, one of the things in there, you have the day of the of the week, you have the day, you have the day of the month, the day of the year, the day of the quarter, you have the week of the year, you have the quarter, you have the month, you have the hour, the minute, the second, and so on, so forth. So you can expand that one field into a bunch of new fields. This is called feature extraction. And it is something that machines can do super well. So you could take that date and explode it, maybe there’s maybe the hour of the day that you were a cup of coffee matters, we don’t know. But you could you could expand that.

    The second type of feature engineering is called feature estimation. And this is where you it’s called predictor importance or variable importance. Let’s say that you expand that date field, all those possible variations. And then you run a machine learning model. With the desired outcome being it was a good cup of coffee does day of the week matter. When you run the model, the machine can spit back estimations of important that say no day doesn’t matter. But our the day does, so can help you tune that. So feature estimation helps you tune your table to avoid adding crap to it all jumbled. All sorts of silly stuff, again, something that machines can do very, very easily. feature correction is the third area. And that is where you’re trying to fix anomalies and errors. machines can partly do that, right? So if there’s a missing date, like you forgot to record a cup of coffee One day, a machine can identify that, again, that’s missing. But they’re getting they’re getting better at but they’re still not great at detecting things like bias, right. So for example, being variety is one of the beans that is one of the features we’re talking about in this this fictional table. If you only buy Columbian coffee, guess what, you got a bias in your data, the machine may not necessarily see that as an anomaly, or as a bias. Like, hey, you only bought one kind of coffee here this whole time. So the the the the feature estimating mattress a this feature doesn’t matter. Well, if you know anything about coffee, bean varietals matters a whole lot. But if you’ve only tested one kind, you got a bias in your data and the machine won’t know to detect that, in fact, they’ll come up with the wrong answer and tell you to delete that column. The fourth area is feature creation.

    This is

    a creative task, being able to to create net new features on a table. So say we have been a variety in there, a machine can look at the data set. And if you got Colombian and a Nicaraguan and all this stuff, it can categorize that, but it can’t add net new data, like an easy thing for us to do would be to add the price that we paid for that can of beans. machine doesn’t know to ask for that he doesn’t even know how to get that doesn’t know that it exists, we, as the humans would need to create that feature, we need to bring in additional outside data was not in the data set in order to create it. So feature creation very difficult for machines, do you need domain expertise to do that, and a follow on Fifth aspect of feature engineering is feature amputation, which is, you know, as the expert, what’s missing from the data set, right. So for example, you brewed that cup of coffee, you got the temperature of the cup of coffee, great. I know as someone who drinks coffee, that there is depending on the carpet served in depending on the time of day, the ambient temperature, there is a lag time between the time was brewed, and the time you put it to your mouth and start drinking it. How long was that time, it’s not the data set. And it’s and you as a data scientist need to know, hey, if somebody let this cup of coffee, sit on the counter for 10 minutes, it’s gonna be a very different temperature that comes right off of the machine. But that is again, knowing what’s missing from the data set cooling time is missing from the data set completely. And so as a domain expert in coffee, you would know this needs to be in there. And so automated machine learning can make the most of the data that you provided. But it can’t really do a great job of detecting bias. It can’t do bring in new data for feature creation and it can’t really can’t do feature amputation. So a lot of these automated machine learning frameworks if you hear companies saying this will this will you know, this is magic all you need to do is putting your data and the rest leave it to the machines? Nope. It will speed up your data process science it will speed up your machine learning it will speed up the outcomes that you get it will make life easier for your data scientists but it is not a replacement. And this is a good example in general of what AI can and cannot do. So will Am I concerned the automated machine learning is going to make data scientists obsolete No. cup of coffee is is a very simple example of just how how off the rails that can go. So good question. important question is the important question to ask. And the answer is you still need data scientist for the foreseeable future.

    Sentiment analysis continues to substantially improve in machine learning, in natural language processing, as our technology improves. We’ve gone from very simple, frequently wrong approaches such as bag of words to very fast, complex systems like vectorization, all the way to the state of the art with deep learning methods. Additionally, new techniques and methods like active learning help our models get better and faster.

    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, Dennis asks, How do you think AI will be applied to better understand consumer sentiment? sentiment analysis is a field where it’s part of machine learning, it’s part of natural language processing. And it is, it has changed and improved substantially in the last year, we have seen some major leaps forward in machine learning when it comes to being able to do more with language generate language, to be able to recreate very human like language, our technology has vastly improved. Just as a bit of history, machine learning and natural language processing used to be very primitive, the most common methodology used back in the old days, like two years ago, was like bag of words where you would have certain words, those words would have sentiments attached to them. There’s a very famous natural language processing libraries that did this, where you’d have words like hate versus love. And that approach was OK, ish. But it really did a poor job of understanding any kind of context, you could, you could say things like, I love the club, baby seals, right? That would be a positive sentiment. But we know every human perspective, that’s that’s a pretty awful negative kind of thing. More has changed on that front bag of words, it’s still used by a lot of software, particularly in the marketing space. But it is, it is largely dedicated by people who are doing natural language processing work. More complex stuff is stuff like vector ization, where you have technology that understands not only the word, but the context around it, the mathematical co occurrences of words, you could say, you would be able to see things that I don’t love, or I don’t hate, and have them be treated as contiguous entities, rather than separate, discrete words. And with vector ization, that then opens up the path to really complex language models, using deep learning methods where machines understand and part and process at the word level, at the phrase level, at the sentence level, paragraph level, and ultimately, the document level understanding how the relationships between these different entities change and grow over time. And that’s where natural language processing today is doing a fantastic job. By having those multiple levels of understanding, we can get very close to truly understand the context of what somebody writes in, like consumer view, or what they say in a video, or what they said in an email, or what someone noted in a CRM, that natural language processing is as really advanced. And there are some newer tools, even newer tools today, things like active learning that are helping, our models get better much faster, because instead of writing a model, and then just being done with it, the machines now are flagging things where they say this, this is a low probability, low confidence entry here, and it will raise his hand say, human help me interpret this, you score this one, you score this exception to most of the rules I’ve come up with. And then it’ll reintegrate our feedback. And use that to keep training improving as models. So active learning, really helping change and improve the game for natural language processing. Which leads you to the logical question, why are we not seeing this progress in marketing tools? Why is it that so many marketing tools are still stuck in 2005, or 2010? When it comes to a lot of these techniques? Well, the answer is cost. And it’s, there’s a couple of different dimensions of cost. One is the cost to include techniques like this in your software, you need someone who knows how to write this code. And that’s a big part. But a bigger part and a part that isn’t talked about a lot is compute cost. Doing deep learning requires big heavy hardware, like GPUs to process quickly, and that the cost of that is starting to come down. But it is still fairly expensive to run that type of compute compared to a bag of words approach, which is a very cheap form of compute. Which means that if you are a software vendor that is making SAS based software, which is the majority of marketing tools, Software as a Service, there’s nothing you download, there’s nothing against all you just go to a website and it and you put in your credentials, and it does the thing.

    in an environment like that, companies have a mandate to keep compute as cheap as possible. So that it scales to as many users as possible. If you have very expensive compute techniques, you can get a slow application very, very soon sooner than you expect. And so those two things, lack of knowledge, and the scalability, are really prohibiting the inclusion of these techniques in major mainstream marketing tools. Now, I think over time, that will change as compute costs continue to drop year after year. And then it’s just the lack of knowledge. And that I think, will eventually be overcome by startups, disrupting spaces. And then being bought by the big players and having the the startup technology integrated into the big players, tools and techniques, that you can get a jump on this by building your own software by building your own tools. Because what is computationally expensive for a software company to deploy to millions of users, is computationally very cheap for you or me to run on a laptop. Right? If you have a modern laptop, and you have the your own natural language processing code, is it a big deal for you to run a piece of software that does natural language assessment in 10 or 15 minutes now you do that your computer gets warm, the fans run a little bit and you go out maybe get a cup of coffee or something come back and and it’s done. That’s not a big deal to us. That’s a huge deal. That’d be a business ending problem for a software company. But for you and me, because we are effective distributing the problem across many computers, I do my version on my computer, you do your version on your computer, it’s not a big deal. So if you want to get a jump on competitors, if you want to get a jump on software companies waiting for them to catch up. Just close that knowledge gap by hiring by creating by buying the software to run in house, on your machines to do this kind of processing, and then you’ll have your answers way before anybody else. So give that some thought. give that some thought. This is a good question Denison it how do we apply this technique? It’s pretty obvious once you understand the consumer sentiment, you can use that information to change what you’re doing let’s make people unhappy and do more of the things that make people happy. That’s that’s the the the use case for consumer sentiment. The hard part is getting accurate sentiment. But good question. As always, please leave your comments in the comments box below.
