    Christopher Penn 0:10

    All right, in this episode we’re talking to Manxing Du from Talkwalker.

    About all things.

    AI and data science.

    So Manxing just start off with, tell us about yourself, what’s, what’s your background? Your how’d you get into data science and machine learning?

    Manxing Du 0:24

    Yes.

    So thank you for inviting me.

    So my name is managing.

    And I did my bachelor, and my master in telecommunications, engineering, actually.

    And then I did my PhD here in Luxembourg in machine learning.

    I started doing data analytics projects, actually, for my master thesis.

    So I did in Research Institute of Sweden, rice.

    So in that project, I analyzed YouTube video, YouTube users watching behaviors, and discuss the potential gains of caching the popular content in the local proxy cache for an efficient content distribution, even though there was no machine learning related in the project.

    But that’s my very first step of entering this domain.

    Christopher Penn 1:28

    Gotcha.

    That’s very cool.

    So you would be telling telecom providers what to cache to reduce bandwidth strain? Yes.

    Okay.

    Very cool.

    And did they did they go into production?

    Unknown Speaker 1:40

    No, no, not really.

    No.

    Gotcha.

    Christopher Penn 1:43

    Okay.

    In terms of data science environments, and things, your what’s your favorite environment for working Jupiter, our studio? And why?

    Unknown Speaker 1:53

    So actually, I use Python all the way.

    But sometimes for a very quick experiments or for data visualization, I use Jupyter.

    Notebook.

    Christopher Penn 2:07

    Okay.

    Why would you so so what do you your Python development in? Is it just a straight text editor?

    Unknown Speaker 2:15

    No, I use PI charm.

    Christopher Penn 2:18

    Okay, recall, in terms of how do you decide when to do something in a notebook versus when to just write up straight up Python code.

    Unknown Speaker 2:29

    For instance, if I just want to quickly show, let’s say, take a look at the data, and to see the distributions of the labels or to see some examples to check the features and so on.

    So that I would use the Jupyter Notebook.

    And to carry out like running experiments, I will switch to two pi charm.

    Yeah.

    Christopher Penn 2:55

    Okay.

    So talk to me about what you do for Talkwalker.

    Unknown Speaker 3:00

    So I joined Talkwalker, actually, almost two years ago.

    And so in our data science team, we mainly work on, of course, finding AI driven solutions for our products, ranging from image processing to natural language processing, both for text and for audios.

    And for me, I have worked on improving our document type classification model, particularly to identify news or blocks, or forum sites, among others.

    And the rest of the time, I have been working on NLP related projects, mainly processing text.

    And, but that’s work in progress.

    And these are, are not publicly released yet.

    And also, I’m also working on some more, let’s say practical issues, let’s say how do we serve our model efficiently and to meet the requirements of the production environment?

    Christopher Penn 4:09

    Can you talk a bit about sort of the evolution of natural language processing? Like we all think pretty much everybody started with a bag of words.

    And just to be very simple tokenization? And where is the field today? And how do you see, you know, the most recent big models like Transformers, how do you see them being used?

    Unknown Speaker 4:31

    So this, like big models, like for example, now very popular ones, it’s transformer based models.

    The most interesting part for that model is it used this contextual embeddings instead of a bag of words, which only embeds each words like independently regarding, regardless of the context.

    So in that case, we One word would have only one embedding.

    And for contextual based in word embeddings.

    So if one word has multiple meanings, and they will have multiple embeddings accordingly, so it has a lot more potential, and it understands the semantic meanings of the word.

    So it would help us to solve many real world’s problems.

    Christopher Penn 5:27

    How does that work with stuff like, for example, like hate speech and abuse of language.

    Unknown Speaker 5:36

    So for that, I think we have, we call them like noises, we have our noise control.

    So we will also, of course, train our model based on the context and then to understand the meaning and then identify them.

    And then, of course, in our training data, I think before we would do other tasks, we would do this noise control, we will try to filter out these noisy data first, and then we continue with other analysis.

    Christopher Penn 6:16

    What if somebody wanted to specifically study, like hate speech? For example? Would they have to have a separate model that was trained specifically for it?

    Unknown Speaker 6:28

    Not necessarily, but I would say we provide general models.

    But if you want like a really domain specific model, it is also possible to train your customized model.

    Yes.

    Christopher Penn 6:48

    How much? How much horsepower? Does it take in terms of compute power for working with some of these models? Like BERT or GPT? The GPT-2 family or the open the Ilica? AI family? Is it something that a technically savvy person could do on a modern laptop? Do you need cloud architecture? Do you need a roomful of servers? For like, epic training time? How? What’s What’s the overhead on these models?

    Unknown Speaker 7:19

    So I think, if I’m not sure, I think some models if you load them, it could be it could take up, let’s say 512, or like one gigabytes, memory.

    And I think normally, if you just want to run like a base model, it’s a modern like laptop can can afford it.

    And but of course, for us, we use, like bigger GPU servers.

    Christopher Penn 7:51

    Yeah.

    Gotcha.

    Okay.

    What are some of the more interesting machine learning challenges you’re working on right now?

    Unknown Speaker 7:59

    So, in general, the most challenging part is, for instance, how do I assign labels to on label documents? For instance, if you, if you have a predefined set of topics, and you have tons of documents, how do you assign the topic for for each document? So a very naive approach would be, let’s say, we define a few, we find a few keywords related to the topic.

    And then we could do keyword matching on on the documents.

    And also, of course, if you want to go one step further, you want to find the embedding of the document, and then you want to compute the similarities.

    And of course, when you choose the model, how would you compute the let’s say the document embedding would you compute word word embeddings, and aggregate them? Or would you compute based on synth based on sentence? So there are multiple choices? And also, how do we for instance, of course, we deal with global data, and then the data documents would be in multiple languages? And how do we deal with that?

    Christopher Penn 9:23

    Do you find like, is there a substantial difference in terms of performance between using the more complex embeddings like from a transformer model versus just using bigrams? You know, sort of going back to the naive approach, but using diagrams.

    Unknown Speaker 9:40

    I never tried actually, but I think because, for instance, if we want to, let’s say find something related to Apple, I guess.

    The rather naive word embedding models would and understand, for instance, between the real fruit apple and the Apple products, right? So I think that would be a challenge.

    And right now I think the big, more complex models it can because of the contextual embedding, and it can understand the meaning of the words so it’s more powerful and more accurate.

    Christopher Penn 10:22

    Okay? Describe your exploratory data analysis process, when you get hand and say a new data set.

    What do you do? What’s your what’s your recipe for unlocking value from a dataset.

    Unknown Speaker 10:36

    So take, right now take this text data, for example, we will check the source of the data set, and if it matches our problem or not, because, for instance, if the data is from social media, or is, is any, like domain specific data, or it’s like, it’s from news website, and so on.

    And of course, we may do data cleaning up and we need to maybe translate the emojis into text and also remove some user account information.

    And also in this process, we need to try our best to D bias the the text as well.

    And, of course, we need to also check the label distributions to see if any of the class if any of the group is significantly more, we have significant, significantly more data than the other groups and so on.

    And also, we can always run some simple baseline models on it.

    And to quickly check the results and also identify, let’s say, the misclassified documents and to see which class we perform better in which class we perform worse.

    Christopher Penn 11:58

    Talk a bit more about what you said D biasing the text, what does that mean?

    Unknown Speaker 12:04

    So for instance, one example is so, emoji comes in different gender and in different skin colors, and so on.

    So we want when we want to translate the emojis into text, we will remove the gender and the racial related text and to keep it as neutral as possible.

    Christopher Penn 12:35

    Are there cases though, where that those factors would be useful?

    Unknown Speaker 12:43

    Yes, I guess so.

    But that’s also always a trade off.

    Christopher Penn 12:48

    So somebody who needed that they would have to do the that data analysis separately outside of the environment you’re talking about?

    Unknown Speaker 12:59

    Yeah, I guess Oh, yes.

    Christopher Penn 13:01

    Okay.

    Why? Why is that step in there.

    I’m curious as to like the decision making processes about why that’s important or not important.

    Unknown Speaker 13:15

    Because I think we right now, we don’t want to make assumptions, or we don’t want to confuse the model.

    And it’s very important to keep our data set neutral and clean.

    We don’t want to introduce too much like bias into into the data.

    So the model may pick it up and may focus on around, let’s say, feature in the data to make the decision.

    Christopher Penn 13:43

    Okay.

    You mentioned labeling of, of sources and documents.

    How do you differentiate because there’s, there’s a lot of, I guess, blurry lines, I’ll give you an example.

    My personal website is listed in Google News.

    Right now.

    It’s a personal blog, I would argue it’s probably not a news source, even though it shows up in Google News.

    How do you differentiate between news sources? And, you know, some random guys block?

    Unknown Speaker 14:15

    Yeah, that’s a very, very good question, because it’s very difficult for us as well.

    We actually work very closely with our product team.

    And then we give a rather like detailed guidelines to to label our data.

    For instance, let’s say if the, in a personal blog, if you are talking about news in a very objective way, and then we we may classify it as news, even though it’s published on your personal blog site.

    So yeah, it’s it’s, it also depends on what our like Clients want.

    So I would say it’s we need a rather clear in detail guideline to label our data.

    Christopher Penn 15:12

    How do you deal with objectivity issues? I’ll give you an example.

    Most of the planet agrees that Russia illegally invaded Ukraine.

    Right? It’s generally accepted as true.

    If you go to the official Russian news website, we have Asti it’s a completely different story.

    It’s basically Kremlin propaganda.

    But RIA Novosti would be classified as a news source is literally the state is the government official news source, just like the BBC is the government official news sources of the United Kingdom? In cases like that, how do you deal with a site that is theoretically accredited, but is completely disconnected from reality? When you’re talking about new sources and classifying something as a new source? Whereas propaganda?

    Unknown Speaker 16:05

    Yes, so in this case, I guess it depends on what you want to use this, how do you want to use this data? So if you want to use it for for instance, sentiment analysis, then I guess your data is highly biased.

    So I would say we will, like exclude them from our training data, because it’s yeah, it was.

    It’s highly biased.

    Okay.

    Good.

    I don’t know it’s

    Christopher Penn 16:41

    in terms of sentiment analysis, how, what is the field look like right now? Because in a lot of the different studies I’ve seen and papers I’ve read, even with transformer models, it’s still kind of a crapshoot.

    Unknown Speaker 17:00

    I would say, for us, I think we, well, it depends, you need to, if you use, like, let’s say, vanilla version of the model, then, like, let’s say BERT is not trained to do sentiment analysis, then of course, you may not have the best performance there.

    And, and also, it’s not really trained for sentence embedding, let’s say, because it’s better to do word embedding.

    And then how do you aggregate them? I would say, you need to find that’s why in Talkwalker, we, we collect our own training data, and also we customize our model and for like, specific tasks.

    So in that case, we will make sure that for instance, for sentiment analysis will will have better performance, they then using a model, we just use it, just take it from the shelf.

    Christopher Penn 18:11

    Gotcha.

    Do you find that these models, how much how much human review of the training data is needed for natural language processing models? Is it some it’s not as easy, for example, is like saying, you know, taking ecommerce sales data, that’s much easier to model.

    Unknown Speaker 18:31

    So I guess we also, so first we collect, let’s say, from from some public data set.

    And so we we know that these data, for instance, are used to build up some benchmarks.

    So they are relatively reliable.

    And also, we will also make labels some data by ourselves.

    So yeah, we have rather good control of our training data.

    And yeah, it takes a lot of time to, to build up our in house datasets.

    Yeah.

    Christopher Penn 19:16

    Talk a bit about the mitigation of bias in datasets.

    You mentioned, obviously, the D biasing of some of the text itself.

    Do you? Is it a valid approach in natural language processing to keep some of the demographic data and use it as a way to remove bias? So for example, let’s say you have 100 articles by 100 authors and have gender information for the authors.

    And let’s say 80 of them are male 20 of them are female, is it in terms of d biasing the data set? There’s obviously a few different ways to do it.

    One of the easier ways would be to take you know, do something like propensity matching find the 20 articles that are most similar to the women’s articles only choose 20 of the In the ad men’s articles, but obviously, you drop out a lot of information that way.

    How do you think about the mitigation of bias, particularly in the problems that you’re being asked to solve?

    Unknown Speaker 20:13

    That’s a tricky question.

    tricky subject? Yes.

    Yeah.

    So I guess I have also, like, watched some, like talks about trading bias.

    And they said is, it’s, it’s always, it’s always a trade off between, you don’t want to remove too much of the demographic information, because you will lose a lot of information as well in that case.

    So I guess it’s depends on your, your task, for instance, you you can keep all the data, and then you do the training, and then you test on your test set, and to see if you can observe any mistakes, let’s say.

    And if those kinds of demographical features really introduced bias predictions, then I would say, maybe we need to deal with it.

    Otherwise, the demographical information, if it’s provides benefits to the prediction, then we we should keep them Yeah.

    Christopher Penn 21:44

    Okay.

    Do you think though, that, and I don’t mean Talkwalker, because of entropy in companies in general? How, how carefully do you see your fellow machine learning and data science practitioners thinking about bias and making sure that it’s a step that they account for in their pipelines, and even in their training data?

    Unknown Speaker 22:10

    I think because we are also fully aware of this problem.

    And so, for us, I think we always when we do data collections, and so on, we need to make sure that datasets are like diverse enough.

    And we don’t collect for instance, from a specific domain or specific region and so on.

    Yeah, so we, we, when we do when we build up our own training data sets, and we are very careful and try to prepare this rather clean and diverse training set.

    Christopher Penn 22:49

    What do you how do you deal with drift when it comes to models, particularly around dimensions, like bias when, let’s say you calibrated a dataset so that it returns the author’s that are evenly split 5050 for gender as a very simple example, but over time, just by nature of the fact that maybe you’re pulling in, I don’t know, accounting papers, or something or pick a domain where there’s, there’s a strong gender bias in one direction or the other, the model will inevitably drift if you just feed the raw data, how do you how do you deal with drift in models.

    Unknown Speaker 23:28

    So, for us, so, before we release our models, of course, we will test it in our production environment and using our production data and to see the proof to monitor the performance.

    And of course, later if we have feedbacks from from our clients that they are not satisfied with the results and if they see some misclassified documents and so on, and it’s always possible to label for instances a domain specific data set and then using our AI engine to retrain the model.

    Christopher Penn 24:13

    Do How effective are systems like reinforcement learning and active learning for these kinds of models in terms of getting feedback from customers, like have customers just thumbs up or thumbs down an article in the results? How does that work as a feedback loop for retuning models?

    Unknown Speaker 24:33

    So, for active learning, I think right now, we have for instance, if we notice that there are certain type of documents or a certain group of documents, they are missing, they are misclassified and then we would add those examples, particularly, we are going to targets those examples and then add them into the training set.

    And we try to learn from those difficult cases.

    Christopher Penn 25:11

    What advice would you give to aspiring data science just and machine learning engineers? What are the what things? Would you warn them about? You know, looking back at your career so far and things, what are the things that you say like, oh, look out for this?

    Unknown Speaker 25:26

    Yeah.

    So I think the first step, of course, right now, we have tons of like, big complex models out there.

    And it’s very fascinating, and we’ll all wants to try them.

    But at the beginning, I think it is always beneficial to select a rather simple model, it could be even a decision tree model, to build your baseline, and to understand your data.

    And, and also, of course, you shouldn’t stop learning, you should never stop learning, because this is a really fast pace, area.

    And you should always keep up with the recent research.

    And also, when you see sometimes the results are incredibly good.

    Always double check, always go back to see to make sure they are not too good to be true.

    Christopher Penn 26:31

    What research and things are you keeping an eye on what things have got your interest that are on the horizon now that are obviously not in production, but that have caught your interest?

    Unknown Speaker 26:42

    For instance, right, now, let’s say we, we need to train a model specifically for for each problem we want to solve.

    And, of course, GPT, three gives us this opportunity to do this zero shot learning and it can just we describe our task and then the model will immediately pick it up and then give us give us the results.

    And I think in that domain, there are still tons of things could be done.

    And also how is it possible to to use or even to downsize such giant model into smaller manageable ones? And use them in production? So So very interesting question.

    Christopher Penn 27:40

    What do you think of some of the more novel use cases of natural language processing to solve problems that aren’t strictly language, there was a case not too long ago, where someone took the sequence genome of SARS, cov, to the COVID virus, transcribed it into essentially words, you know, RNA fragments, just the letter sequences of the amino acids, and then used natural language processing to try and predict mutations with a fairly good degree of success.

    Without How much do you keep up with, you know, the way these models can be transferred from one domain to another?

    Unknown Speaker 28:17

    Yeah, I have seen those kinds of usage.

    I guess you can also, let’s say applied NLP model in the music domain.

    I think they are all of these usage are quite interesting.

    And then it also shows how powerful right now this natural language models are.

    Yeah, and I think they are.

    It’s definitely these models have the potential to solve the problems in other domains.

    Christopher Penn 28:53

    Do you think they’ll be sophisticated enough at some point that we’ll be able to use them for example, to restore lost languages?

    Unknown Speaker 29:05

    Yeah, I guess because I think right now.

    So these models could pick up, for instance, some similarities between different models.

    For instance, one multilingual model, if you train them on one task only in English, and then you test it on the same task, but in another language, it’s also it wouldn’t give you a really top performance, but it’s it’s also the results are also quite are quite impressive.

    So I think the model has the potential to to pick up the links between the languages, so yeah, maybe why not.

    Christopher Penn 29:54

    Okay.

    And what advice would you give to non technical folks In particular, when they’re thinking about artificial intelligence, because they seem to have, they fall in one or two camps that there seem to be disbelieving of it entirely, or they think it’s entirely magic and can do anything, including, you know, create Terminator robots and, and other things.

    How do you talk to executive non technical executives about what AI can and can’t do?

    Unknown Speaker 30:24

    So I think personally, I would say we should definitely, definitely embrace the enormous the enormous potential of AI.

    And, but also at the same time, we, we need to be well aware of the limitations AI cannot do everything.

    For instance, right now, the models, people are mistakenly think the models tells us the correlations between features.

    But here, the correlations are not equal to conversations.

    So for instance, on Valentine’s Day, and if you see, oh, we have rather high price for the roses, and at the same time, we have also a very high sale of the roses, and they are highly correlated.

    And but it doesn’t mean you cannot draw the conclusion that oh, so we should in order to have a high profit, a high sell of roses, we should increase the price, because high price is the cause of the high sale of the roses, which is wrong.

    So I think here people should be aware of all these limitations, and also, when you interpret the results, how to explain how to understand the results correctly.

    So so very important.

    Christopher Penn 32:02

    How do you deal with? So with a model like GPT? Three, for example, there is no interpretability or explainability of it, it really is very much a black box, given the interest of governments and things, rightly so about how machines are being used to make decisions.

    How do you deal with a situation like that? When when somebody says, Well, how did how did the model come up with this answer? And you have this black box? What do you tell somebody?

    Unknown Speaker 32:35

    Yeah, so I guess this Explainable AI is also a very hot research topic right now.

    So uh, but I guess, for instance, if you look at Chatbots, or you let GPT-2, three to read your story, you can read the story, and then easily probably tell, oh, this is not really a human written.

    Text, it’s it, it looks or it’s, it seems not consistent, or rather, looks weird.

    So maybe you can emit immediately see, it’s not generated, it’s not written by, by human.

    So I would say, in this case, we are still a bit far away from the real, let’s say, intelligence machine.

    Christopher Penn 33:44

    Okay, how to how to you personally, and I guess, from a professional and corporate perspective, I plan on dealing with the absurd amount of content that’s going to be generated by a lot of these natural language generation models, where they’re going to create you know, instead of one really good blog post, they’ll generate a million mediocre blog posts that are you know, that still meet their goals, which is, you know, keyword density or other things for mostly for SEO, but will flood all of our public Commons I guess, with with machine generated stuff that is okay, but not great.

    You know, how do you how do you see companies dealing with just this massive explosion of content?

    Unknown Speaker 34:37

    So I guess in this case, the first task is to identify which text are generated by machines and which are the real let’s say comments the real articles written by by human Yeah, I guess in the future may be the Let’s say the noise control engine should should also try to identify.

    So this is also one of the major tasks in the future like to first future out the machine generated text, and then to find your interested up human generated content.

    Christopher Penn 35:31

    Particularly with comments, though, like on product reviews and things, I see it being really difficult because on one hand, you might have a machine generated comment that, you know, hat might have a marker or two like, okay, that that word choice is not how you would normally say something, but it could be somebody who’s not a native speaker of that language.

    And on the other hand, you have comments that are just put up by human idiots.

    I was reading an Amazon product reviews say the other day about type of apple juice, and like, it doesn’t taste like fresh apples at all.

    Like it’s not it’s it’s dried apple powder.

    Of course, it’s not going to taste like, you know, we’ll apples, you idiot.

    This human just wrote this absurdly stupid comment on a product.

    But you can easily see that a machine learning model.

    Trying to understand comments might actually think the machine comment was more useful and valuable, even though it’s generated but not by a human, then the what the idiot human wrote.

    And it poses this challenge, I think of the machines might actually write better product reviews.

    But they’re fake, they’re not a real authentic review, then what the human idiot wrote? How do you see companies dealing with that, particularly a company like Amazon, where they’re gonna have, you know, people who have very strong interest in bombarding a product with, you know, as many fit 1000s of fake reviews possible to to boost the ratings.

    Unknown Speaker 36:53

    So I guess those machine like the fake accounts, maybe you could also look at their account names and find some patterns, and also how often they post you could, I think, from other aspects, other than only looking at the text they generated, and also sometimes this machine generated text, they may put, maybe put lots of, let’s say, emojis or adult ad links, and so on.

    So I guess you need to, if let’s say we can identify those comments, easily if then we should maybe filter out those comments and then maybe try to study the pattern? And yeah, otherwise, if, if those comments if those accounts are even difficult for us to identify them? Yeah, how can machine identify them?

    Christopher Penn 38:01

    Right.

    I mean, that’s the challenge I was having was like, did a real human read this good? I can’t believe well, and I looked carefully, like he said, looking for other views.

    And like, No, this actually was a real just stupid person.

    Machine.

    Christopher Penn 0:13

    In today’s episode, Heidi asks, are companies challenged in their adoption of AI by siloed data? I would say that it is certainly a contributing problem.

    But I think siloed data is a problem period, right? Regardless of whether we’re talking about AI or not, if we think about artificial intelligence really is just like a fancy kitchen appliance.

    And it does really cool stuff.

    Think about what siloed data would look like, suppose you were trying to cook in a kitchen, and there were some ingredients you had.

    And there are some ingredients that were in another part of the kitchen and you weren’t allowed to go in that part of the kitchen, right? Like, the the stuff in the refrigerator, you’re not allowed to go in there, you can’t go in the refrigerator.

    Like my supposed to make bread if I can’t get it, you know, the eggs or the milk or the yeast or things like that, I’ve got flour here, and then you start getting protective? Well, if I can’t go in the frigerator, you can’t come in my pantry.

    And you know, you can’t have flour, sugar or salt.

    Obviously, it’s going to be a really rough day in your, in your kitchen.

    If you start having these silos, these organizational divisions that prohibit people from sharing ingredients, data is an ingredient.

    And again, AI is just a fancy appliance, which means that if you have those silos, you’ve got problems that AI won’t solve, right? If you have, it doesn’t matter how fancy your new blender is, if you’ve got if you’re not allowed to go in the refrigerator, there’s a lot of things you can’t cook period, blender or no.

    And so from a, a structural perspective, companies need to get rid of silos as much as possible within practical and regulatory limits, if they want to be able to make use of the data for anything, not just for use with AI, but for anything at all.

    If you’re building a data warehouse, or a data lake, if you’re doing even basic, you know, pre machine learning stuff, if you’re just doing basic statistics, exploratory data analysis, you need to have access to the data to do that.

    And if there are silos, it’s going to be it’s going to be a rough time, there were there will be things like you know, if you’re not allowed in, in the, in the freezer section of your of your houses, kitchen, there’s gonna be some things you’re not allowed to do that.

    And that you will need, you will need access to.

    So here’s where artificial intelligence can help.

    Sometimes if if we make an AI project, fancy enough and flashy enough, you know, it’s the shiny new object in the room.

    Sometimes that can help break down organizational resistance.

    If AI is a strategic priority your company, you can go to somebody and say, oh, yeah, I know, you know, normally, we’re not going to access your, your sales data, or whatever.

    But for this project, we’d like to make an exception.

    And depending on the benefit to that division of the company, depending on the visibility at an executive or stakeholder level, sometimes you can use AI as an excuse to dig into those other silos of data and get stuff out of them.

    This happens a lot.

    We’ve had this happen a lot with analytics projects, big analytics projects, where ironically, as a consulting firm Trust Insights would have access to more of the company’s data than any individual one department did.

    Because we were an outside neutral third party.

    And so we’re just like, oh, yeah, we’re just gonna use this data for this project.

    Meanwhile, we had better visibility into the entirety of of what was happening at a company and be able to share back with those divisions, hey, here’s what else is going on at the company.

    It’s kind of like, kind of like being the data and AI equivalent of a bartender right? Everybody comes to the bartender and confesses their their woes individually.

    And you as the bartender, you have, you know, hear everybody’s stories and go, yeah, and you’re thinking, Oh, Ralph here has got the exact same problems as Bob over there.

    And she was always there, she’s got her problems and stuff.

    And you all don’t know that you each have the solutions to each other’s problems.

    Because you don’t talk to each other, you just talk to the bartender.

    So AI can be used as an excuse to get into other silos.

    And then ideally, what you do is you show benefit to sharing data that goes above and beyond the scope of the AI project itself.

    So that it persuades those those silos those departments like hey, if you share your data, things will be a lot easier for both groups, both groups will benefit.

    The worst case I’ve ever seen of this was just blew my mind.

    We had A B2B tech company a few years back as a client, and we were called in to build a model of their marketing data,

    Christopher Penn 5:10

    combining marketing and sales data to help them essentially figure out which channels mattered the most.

    When we got in there, we were told, here’s the marketing data, for regulatory reasons, some data that we can’t get about our own company that we can’t like the market department, and we can’t get it.

    So not that we won’t share it with you, we can’t get a hold of it, can you see if you can get it from the outside, we were able to do that.

    And then we asked for the sales data so that we could calibrate the marketing data with the sales data to say, Okay, if you have all these things, and this is the outcome you’re after, and the VP of sales is like, Nope, can’t have that data.

    We’re like, why not? Because marketing is not allowed to see sales data.

    Like, how do you get anything done? Then like, how do you communicate to marketing? Hey, you know, these programs are driving leads are not driving leads, and like we don’t know, like, so.

    You just wing it? And except whatever leads marketing sends you and it’s like, no, no, we don’t we don’t do that.

    Whatever marketing sends is incremental, our sales guys all just cold call everybody all day.

    Like, I feel like, I feel like that might not be the best way to do things.

    It turns out, this came out.

    After our engagement, that sales was so poor at its job, their closing rate was so bad, that they didn’t want anybody to know just how bad things were internally, there’s their sales closing rate for, you know, good sized commercial enterprise deals was something like about 1% of every out of every 100 opportunities that were teed up, there’s the sales tour and closed one of them.

    And so there was a lot of obviously house cleaning and personnel changes and things.

    We didn’t have anything to do with it, because we were long gone to that point.

    But I remember reading in the news about this company, because it’s pretty well known company that they had run into some revenue issues.

    And I’ve had a few quarters.

    And I’m like, Huh, I wonder that is because y’all are flying blind and have no idea what you know, the left hand has no idea what the right hand is doing.

    So there are definitely challenges posed by siloed data AI is no different than any other function or any other technique used to turn data into insights.

    It is hampered more by missing data.

    But if a company’s got siloed data and rigorous boundaries between departments, it’s got problems already, right.

    And AI will not solve those problems.

    It will just make those problems.

    bigger and faster.

    Right.

    That’s what AI does makes things go faster and bigger.

    And you know, if you have solutions that will make your solutions faster and big, if it makes you have problems it will highlight and make your problems faster and bigger too.

    So really good question.

    Thanks for asking.

    Christopher Penn 0:13

    In today’s episode, Heidi asks, What challenges keep you from examining and or using AI for your current marketing? Oh, I, we don’t really have that problem, because we do use AI for a lot of our current marketing.

    But let’s take this from the perspective of, say, a client, there are a bunch of different challenges that can keep a company from using artificial intelligence.

    First, and probably most fundamental is bad data, right? So if the data that the company is working with is bad if it’s in bad shape, if it’s, you know, in also the wild and crazy, wacky formats, if it’s in hard to access systems, it becomes very difficult to use that data for predictive purposes, or even just for classification purposes to figure out what data do we have.

    And this becomes really relevant when you’re doing something like for example, attribution analysis.

    If you have missing data from your attribution analysis, and you’re doing really big model something using maybe like Markov chains, or certain types of decay models, were even just multiple regression models.

    And you’ve got missing data data that is important, but you don’t know that it’s missing, you can build an attribution model that will not be correct, right? It will be something we’ll be off.

    And you may or may not know that it’s off.

    So in in cooking terms, if you were to think about it, some cooking terms, imagine baking a recipe or baking a cake, and you leave out an ingredient.

    And it seems like it’s okay, but in fact, it’s not.

    Okay.

    Right.

    So maybe you’re making chocolate cake, and you leave out the cocoa and you have something at the end that’s edible, right.

    And it’s, it tastes like cake.

    It just doesn’t taste like chocolate cake.

    And if you’re doing something like unsupervised learning, where you don’t know what you what’s in the box, you may think, oh, yeah, this is vanilla cake.

    And in fact, it’s supposed to be chocolate cake, but you don’t know that you missing the cocoa.

    And so that’s an example where bad data in this case, missing data can have a substantial impact on the model.

    The second thing that causes issues, and sometimes very substantial issues, is thinking about artificial intelligence as a solution.

    Artificial Intelligence is a set of tools, right? Think about? Imagine if we as business folks, we talked about AI the same way we talked about spreadsheets, right? We go around saying, Well, should we use a spreadsheet for this? Maybe this is a spreadsheet problem.

    Let’s let’s, let’s try using spreadsheets for this.

    And you get how silly that sounds, right? If you’re dealing with something like say, you know, public relations stuff, like writing a better media pitches, spreadsheets, probably not going to help you do better writing, right? It may help you categorize say, the prospects that you’re pitching, but an unlikely spreadsheets going to help you write a better pitch.

    A word processor wouldn’t be the better choice.

    And so one of the things that happens with artificial intelligence is that people think that it is a solution when it really is just a tool, right? It’s if you’re in the kitchen, and you’ve got a blender and a food processor and a toaster and stuff like that.

    Do you say well, what can I use my toaster for today? No, I mean, you probably don’t think appliance first, when you’re cooking, right? You think about objective first I want bacon and eggs, I want a pizza, I want sushi.

    I want you know something along those lines.

    And then you reverse engineer based on what you want.

    Do you have the ability to make that dish, right? If you don’t have rice, and you don’t have a rice cooker or some means of cooking rice, you’re not having sushi, right? If you don’t have a blender, you’re probably not having a smoothie.

    I mean, you could but it’s got to be a lot of work.

    And so

    Christopher Penn 4:17

    if we think of AI as essentially a fancy appliance, then suddenly it is less about using the technology like I’ve got to use this convection oven.

    No, no, you’ve got to make a dish that you want to eat.

    And then maybe AI is the right choice.

    Maybe it’s not.

    Generally speaking, artificial intelligence is really good at problems that have a lot of complexity and a lot of data and a lot of data.

    So if you are dealing with a problem that doesn’t have a lot of data, AI may not be the right choice for it.

    Right AI may be the wrong choice for that problem.

    In fact, there are certain problems where AI makes things more complicated, right? Where it’s just not the right fit.

    It’s like trying to use a blender to make an omelet.

    I mean, you can, but it’s not going to taste very good.

    You’re much better off using a frying pan.

    So those would be the major challenges where I think people run into trouble.

    When companies are hesitant to adopt AI, it’s because they don’t understand the technology itself.

    Right? So getting a kitchen appliance, you don’t know what it does, you’re probably not going to use it for your big dinner party, right? You’re probably going to take some time and say, Okay, let’s let’s see about maybe using something we know.

    And so, if we want to encourage more adoption of AI, we’ve got to simplify people’s understanding of what it does, right? If you take apart your blender, this can be all sorts of stuff, their controllers, chips, solenoids, you know, depending on how fancy your blender is, do you need to know how an electromagnetic motor works.

    Now, you just need to know what the blender does and what it’s good at and what’s not good at right? The inner workings really aren’t as big a deal.

    AI is very similar, right? You don’t need to know how a neural network works, you need to know is the right appliance for the job.

    And to do that you’ve got to have problems that are well suited for using AI.

    So those would be my my challenges that I think people struggle with.

    With artificial intelligence.

    The rest of it really is just math.

    It’s just math and data.

    So if you can grasp the strategic uses and the conceptual uses, the implementation is relatively straightforward.

    Not easy, but straightforward.

    It’s not overly complicated once for most marketing problems.

    So really good question.

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

    Christopher Penn 0:13

    In today’s episode, Ashley asks, How can I make the case for AI and marketing? Well, here’s the this is a challenging question, here’s why it’s challenging.

    That assumes that you have a problem for which AI is the best solution.

    Right? And that means you need to understand what things AI is really good at, and what things AI is not good at.

    Right? Fundamentally, artificial intelligence is good at two types of problems, right classification problems, and regression problems for the most part.

    Now, there’s, there’s some flexibility in that, but those are the biggest, broadest categories.

    If you got a bunch of stuff that you need to categorize and classify.

    AI is actually really good at that.

    particularly things like images, audio, video, text.

    Classification, is a particularly strong area for AI to do its work.

    And regression, or which leads to prediction AI is reasonably good at things like that forecasting, trying to understand what contributes to an outcome.

    What are the drivers of an outcome? AI is pretty good at that.

    So the question is, do you have a problem for which AI would be an appropriate solution? There are a whole bunch of problems where AI is not be answer.

    For example, in some there’s some kinds of forecasting where simpler statistical methods like auto regressive integrated moving averages still deliver best in class performance, better than neural networks better than, you know, really complex regression algorithms and machine learning powered regression algorithms something sometimes, and ARIMA result is perfectly fine.

    So a major challenge for somebody who is not a data scientist is to understand which problems are suited for AI and which are not.

    If you’ve got a problem for which there is a lot of data, both for the problem itself, and for past solutions than AI is probably a good candidate, right? Say you’ve got a million pages of text, and that that have good examples and bad examples of writing.

    And you got 10,000 new pages, you need to assess are these good or bad.

    With that much data, AI is actually a really good solution.

    Because there’s enough information to train a model, which is fancy for have AI write software for itself, that it can successfully build that model, and then run it against your production data.

    AI is also really good at in general data where there are clear patterns, and clear repetition that requires scale, right.

    One of the big challenges with AI problems with just throwing a at a problem is that there may not be enough data to create that model, right? If you’re trying to say build a model to write great corporate blog posts for your company, and you’ve only got like 200 blog posts, you’re gonna have a hard time, that’s not impossible, you can take an existing model and fine tune it.

    But for the most part, that’s not enough information to really help it it build a good robust learning data set a training data set for to generate the outcomes you want.

    On the other hand, if you’re a company that you’ve got 2 million blog posts, then you’re talking, right, and now you’ve got enough to cook with, it’s kind of like, there’s a minimum amount of ingredients you need for a recipe to work, right.

    There’s some ingredients, some recipes, where if you don’t have a sufficient number of ingredients, it never reaches critical mass and it doesn’t work.

    Like you can’t really bake a loaf of bread with a quarter teaspoon of flour.

    I mean, if you scaled down all the ingredients, there’s just not enough mass there for the recipe to work properly.

    You know, the same is true for like a model cars and stuff below a certain scale size.

    An internal combustion engine simply doesn’t work.

    Well if it’s like this big.

    Right? And that’s the challenge you face with with artificial intelligence.

    So big data in means that you’ve got a good case for AI.

    Christopher Penn 4:43

    If you find a problem has no repetition, it’s a bad candidate for AI.

    Right.

    So this is one of the reasons why we all often say AI will take tasks and not jobs because your job from day to day is wildly different.

    Right? different meetings, different participants, different activities, different kinds of lunch you eat, there’s a whole bunch of these random variables.

    But within your job is a series of tasks.

    And sometimes those tasks are highly repetitive.

    And if it’s highly repetitive, then there’s an opportunity potentially to bring in some, some machine learning to pick up that individual task and automate it.

    When I am putting together my weekly newsletter, the process is exactly the same week after week and automated a substantial part of it because it’s so repetitive.

    However, there’s still a decent chunk of it that is manual that is human because that part is wildly variable.

    Things I feel like writing about that week, vary wildly from week to week.

    So do you have a case to fit to make for AI? If you have a lot of data, and it’s highly repetitive? One of the things people are thinking about is does AI or machine learning? Does? Is there a case to be made based on cost savings.

    And this is tricky, because it depends on the task.

    It depends on the task.

    And it depends on the complexity, and all the stuff that we’ve just mentioned.

    There are definitely things where it doesn’t pay for a human to do it.

    So like curating content for social feeds, right, that is a machine based task, for sure.

    It’s relatively low value, highly repetitive, big data.

    And solving for it is worthwhile, right, because you can take some, you know, two hours out of somebody’s calendar each week, and turn that into five minutes, that’s two hours back that you get that you can do something else with that time.

    On the other hand, there are some tasks where the creation of the model and the maintenance of the model would be so vast, that you’d be better off doing it manually, right? Like shooting your video each week, if I were tried to have a machine do this entire video from beginning to end, the enormity of that task and the high variability of it would be so difficult that it would take me years to make it happen.

    And it wouldn’t be worth the return on investment would be a negative.

    So that’s a major part of this question is, when you’re making a case for AI, can you make a case for a positive return on investment for its application? This is one of the reasons why Artificial intelligence has not been widely adopted by many businesses.

    Because in a lot of cases, people are treating it as this magic wand.

    And as a result, they’re not doing a simple cost benefit analysis and saying actually, this is a problem that isn’t worth solving with with machine learning.

    Better off solving with basic statistics or an Excel spreadsheet or just doing it manually.

    Yeah, real simple example I influencer identification.

    There’s a whole bunch of different ways to do it.

    But if you’re validating the feeds of influencers, and you do it once a year, it’s probably not worth automating.

    If you’re doing every day, then it’s worth automating.

    So that would be my suggestion.

    But how do you make the case for AI figure out if you’ve got an AI problem to begin with before anything else? Thanks for asking.

    We’ll talk to you soon.

    In today’s episode, Fabrizo asks, Can you make the intro shorter? Yes, the intro is now 60% shorter from 30 seconds down to 12.

    Now, Maureen asks, why do people use machine learning and AI these two terms interchangeably? Well, the reason is because honestly, it’s because I think most people don’t have a good sense of what either term means.

    And so they just kind of mix and match.

    To be clear.

    Artificial Intelligence is a an umbrella term that is specific to teaching machines to develop intelligence skills that we have naturally.

    So if you are watching this video, and you can distinguish me from the background here, right, you’re using vision, if you’re hearing the audio to this video, and that’s not just noise, you’re able to distinguish things like sounds, different sounds you’re using hearing, right? If those sounds get turned into words, you’re using what’s called language processing.

    All of these are intelligence skills.

    And when we teach computers to do these things with artificial intelligence, right, it’s an intelligence skills that we’re teaching to a machine, rather than being something that’s natural, done by humans or other animals to obviously, things like parrots can certainly learn to repeat words and such.

    machine learning is a subset of artificial intelligence, it’s part of AI, but it is not all of AI.

    And machine learning, specifically refers to giving data to machines from which they can write their own software, right, they can build their own code, based on the information they’re given, and a pre defined set of tools and algorithms to build their own code.

    All machine learning is AI, but not all AI is machine learning.

    Right? So it is a subset.

    Why people use these two interchangeably, partly, partly is a marketing reason.

    In some ways, artificial intelligence has been a buzzword now for about 10 years.

    And as such, has sort of lost its luster.

    Understandably, so.

    There have been many, many AI projects that have gotten off the ground that didn’t really go anywhere.

    And there have been a number of movies and TV shows and things where consumers and the general population were introduced the concept of AI and it created these mistaken perceptions about what machines are capable of people think of, you know, the Terminator, and killer robots and Star Trek.

    And all of these different types of artificial intelligence that are more properly artificial general intelligence, which means machines that are essentially sentient, no such things exist as of this recording, and so for distinguishing that sort of consumerization of the AI term, a lot of folks have said, Okay, well, maybe we should focus in specifically on the machine learning part.

    Given data, we’re teaching machines to do other intelligence tasks and create their own software.

    Most of the artificial intelligence that you interact with on a day to day basis is machine learning.

    From recommendations that you get from Google Analytics, from recommendations you get on Amazon when you’re shopping and says You might also like these three other things that are somewhat related to what’s in your cart, every time you fire up Netflix, and it suggests another series, or you fire up Spotify, it says, Consider adding these songs to your playlist.

    All of that is machine learning.

    There’s yet another distinction that people like to make the differences between classical machine learning and deep learning.

    Deep learning is when machines are not only writing their own software, but they’re also choosing their own algorithms based on all kinds of data inputs and these neural networks.

    The closest analogy I think you could easily make as if machine learning is a chef with a lot of very expensive, fancy machines that do you know 90% of the prep work.

    Deep learning really is a kitchen that almost completely runs itself, right? There’s there’s very little to no human intervention a lot A lot of the time,

    Christopher Penn 5:02

    the challenge and the reason why you would pick one of the over the other is based on the amount of data you have.

    Deep learning requires a lot of data, we’re talking millions of records, millions of samples from which the machine can create a neural network.

    Oftentimes, especially in marketing, we don’t have millions of examples to train on.

    So when we have something, for example, like the GPT, Neo X, natural language generation models, that’s trained on 800 terabytes of text, right, the entirety of Wikipedia, the entirety of Google Books, there’s tons of information to work from when you’re trying to build a model for your ideal customers.

    But you don’t have 10s of millions of ideal customers, right? If you’re a B2B company, you probably have like five ideal customers, right? That the CMOS of the Fortune 10 Are your ideal customers.

    And so those cases where classical machine learning makes a lot more different, much more of a difference is much more effective than deep learning.

    So which term should you use depends on which application if you’re talking about the overall teaching of tasks that are currently done by humans, vision, listening, language, etc.

    AI is a perfectly fine term to use.

    If you are talking about the feeding of data to machines to build their own models, you’re talking about machine learning.

    If you’re talking about building neural networks, out of very large data sets, you’re talking about deep learning.

    And there’s a few other more specialized terms in there, but those are probably not as well recognized outside of the AI field.

    So don’t worry too much about them right now.

    The last caution I will offer is Buyer beware.

    A lot of companies will say that they use artificial intelligence or machine learning and in fact are not.

    In 2018.

    The Financial Times did a survey of 100 companies that were claiming to use AI and did some substantial background investigation found that 35% of them were just outright lying.

    They had offshore outsourced humans doing the work instead.

    So just because something is using AI or machine learning a doesn’t mean it actually is and be doesn’t mean that it’s it’s any good, right? I can use machine learning to overcomplicate nearly any problem.

    It doesn’t make the solution better.

    It just changes what technologies are in the solution.

    So really good question.

    Machine-Generated Transcript

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

    Alright, let’s get going here we have Max asking, Do you think that it is possible at AI, artificial intelligence becomes more advanced to the point where an algorithm or deep learning can develop its own conscious thoughts? Today? No.

    In the near future? No.

    The challenge with consciousness as we understand it right now, is that it is a massive interaction of a computer network, right? A massive neural network.

    What is in your pocket, right? These devices as smart as they are as connected as they are? This is really, you know, I think this phone has like, eight cores, eight processors or whatever, something like that.

    Now, your your laptop like I’ve got a brand new MacBook has got 32 cores.

    Your brain even though it is electrochemical, which is slower than than silicon, then then these things is trillions of interconnected processors.

    And it is that network that gives rise to consciousness.

    These devices, this hardware doesn’t have the ability to do that, right? There’s simply not enough, there’s no way to cram that many processors into a compact enough space where consciousness can emerge.

    Now, I say that that’s not enough time soon, but it doesn’t mean it’s impossible.

    One of the limitations of these things that our brains don’t have is because of the way things are networked together.

    Silicon processors can’t, they have no, they have no middle states, right, they’re either on or off zero or one.

    And our brains don’t work like that.

    We do have firing thresholds for neurons, but for the most part, we’re less zero to one, there’s there’s a lot of variants between zero and one.

    Now there is a form of computing that is getting towards that.

    And that is called quantum computing.

    Quantum computing allows for minus one to positive one and all the values in between, for a, a computation to occur in a processor.

    And we’re still only at like 130 Quantum cores.

    So we’ve got a long way to go, before we get to the trillions of cores needed to replicate what’s in here.

    But you can see a path forward for that, you can see a path forward where quantum computing will eventually give us the ability to have emergent consciousness from machines.

    Now what that looks like and when that happens, we have no idea it could be within my natural lifetime, it might be longer than that.

    A lot of it is contingent on physics, on the constraints that physics imposes on these types of computers.

    But it is possible and when that happens, we are going to have a bit of a reckoning as a society to figure out what all constitutes consciousness what all what all do we have to do about ethics and things when machines can actually think and feel for themselves? They cannot today, but they could at some point.

    So really interesting question Max.

    Thanks for for submitting Matt.

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

    Paul asks, looking back on the way you learned about AI, is there anything you wish you would have figured out first? Yes.

    So machine learning and data science really are a blend of, of four different areas, right.

    So there’s the business side, it’s the business problem, the the business strategy you’re trying to solve, there is the data engineering side, which is handling data.

    Storage, being able to, to retrieve and rank an index data this that you have stored, there is the coding side, where you have to be able to read and write code in a language like R or Python, which would allow you to be effective.

    And then there’s the mathematics, you know, statistics and probability side, knowing the advanced mathematics, so that you not only know what the machines are doing, but you know why, you know why certain algorithms make for better or worse fit, certain techniques make it for better or worse fit.

    And when I look back, I’m self taught on a lot of this stuff.

    So I have a lot of gaps.

    In my knowledge, particularly on the mathematics side, I can patch gaps pretty easily on the code side, I know the business side.

    I know the data engineering side fairly well actually, because I have an IT background, but my my weak spot, my blind spot really is on the mathematics side, particularly once you get into stuff like linear algebra and things like that.

    Higher level mathematics, that’s when I feel the biggest gaps.

    And so from a professional development perspective, certainly, that’s something I wish I had known, more of going into this.

    And certainly something that I’m spending a lot of time nowadays, trying to remediate so that it’s not as big a weakness, right? It’s not as big of a gap.

    do a self assessment in those four areas and figure out which area are you weakest in? Which area are you strongest in, and then try to patch those weak spots, particularly if you’re still in school.

    Definitely take the time to patch those weak spots, take an extra course in something that you know you’re not good at.

    So that it’s less of a vulnerability or added also it’s at the very least, you’re not going to be paying a lot of money to an institution to later on to reteach you something you have to learn the first time around.

    Good question.

    Machine-Generated Transcript

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

    Okay, let’s get started.

    The Kelsey asks, If you were to start writing your book now, this is AI for marketers, instead of when you wrote it, what would you change and why? Well, the challenge with writing any technology book is that the moment you hit publish, it’s out of date.

    And that’s doubly so for a fast moving field like artificial intelligence where you are creating a something to be read and consumed.

    While the technology it’s about is racing ahead.

    When I finished the third edition of this thing, I had some stuff on language models and image generation.

    But so much has happened in just a year.

    That it’s you it’s out of date enough that there are possibilities now that are excluded in that book, right? I don’t mind having something out of date, if there are percentage points, improvements in performance, or, you know, refined capabilities.

    But the technology pretty much does the same thing.

    But what’s happened in the last year is we’ve had leaps of functionality change in artificial intelligence, the ability for us to generate imagery, from a prompt from, from a series of text prompts, is one of the most frequent examples, recent examples from Nvidia came out with that and go again to and then a bunch of consumer apps for your smartphone have come out as well.

    That’s a game changer for functionality, the GPT J 6b Library, the natural language generation library, again, huge model that does autocomplete of like entire documents.

    That’s a game changer because it reduces the burden for us as humans to generate stuff like you know, a press release, right, you can write a press release better than we can, it’s still not great because press releases in general are not great, but it is different.

    So I would obviously change those things to was the process of writing the book.

    One of the things that I think would be interesting at some point is to do a book that’s more collaborative.

    Every single one of my books that I’ve written so far, really has been my point of view on stuff without any outside voices.

    I think it may be time at some point.

    Maybe it’s the the new thing I’m working on right now, where bring in some additional voices for some variety.

    So good question.

    Thanks for asking.

    Machine-Generated Transcript

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

    Alright, Lane asks, although AI can help solve various issues we face today can also create discriminatory algorithms.

    What solutions do you post to solve the problems AI causes? Well, here’s the thing.

    Everything that happens with machines comes from human data, right? There’s nothing that is outside of our existence.

    And so the problems that we see with bias in AI and machine learning come from us, right? The humans, we are the problem.

    And the problem occurs, the problem can occur in a variety of areas.

    It can be the people we’ve hired, right, if people, the people we’ve hired have biases, it doesn’t matter what else you do, you’re going to have problems, right? So that’s a huge part, it’s an overlooked part of machine learning AI is what are the biases.

    Remember, there’s two kinds of bias, right, there is human bias, you know, maybe you don’t like people with red hair.

    Maybe you don’t like people of a certain race, or religion or whatever.

    Those are human biases.

    And then there’s statistical biases, which is just where a sample is not representative of the population, the sample is drawn from.

    The people that you hire, have got to understand both of those, and know to look for both of those in the data that they’re working with.

    Right? So if you’re looking at, say, some survey data that you’ve done before, in some market research, and you don’t know how to check to see whether the sample is representative or not, you could have some really serious problems.

    So people is first second overall strategy, is there a bias inherent in your strategy? I remember a number of years ago, my wife worked at a market research firm.

    And the they were the epitome of what not to do in market research.

    They were a conservative sort of Think Tank.

    And people would come to them saying, I need research that backs up this point of view, by anybody who knows anything about market research and statistics knows that that’s pretty much the worst way that you can do market research other than just making things up completely.

    And so the strategy can have biases in it.

    The data can have biases, and there are mitigation tools for that, for toolkits, for example, like IBM’s AI fairness, 360 toolkit that can look at your data and say, Hey, these look like protected classes like gender, or religion, or ethnicity.

    And it looks like these are non representative values in here like, hey, for some reason, this entire dataset, which has a gender field, is like 98% men and 2% women, you might have a problem in your data.

    So what these tools can do to identify biases in the data set their biases that can creep in, in the choice of algorithms.

    And again, more advanced tools like IBM Watson Studio have some some protections built in to avoid those problems, or mitigate them or at least identify that there’s a problem.

    And then you get bias in the model as it drifts, right.

    So you publish a model, it’s in production.

    And then over time, as it gets new data and learns from new data, it becomes less and less accurate, it drifts.

    It also may have biases in it that cause drift.

    The most famous example, this was back in 2016, Microsoft Tei.

    They focus on Microsoft created a twitter bot.

    And it learned from the tweets people sent it and it became a racist porn bot in less than 24 hours.

    There were no protections on model drift.

    And so each of these areas where bias occurs or can occur has some level of protection you can build into it, but you have to know to think about it to look forward to ask questions about it.

    You’ve got to have a way to identify it in the hiring process.

    You’ve got to have a way to for a safe way for people to raise concerns in the workplace, right if they see a strategy that’s clearly biased in some way that’s That’s incorrect.

    There’s got to be a safe way for people to elevate their concerns and and have those concerns answered.

    Again, using tools like fairness 360 for the data, using tools like Watson Studio for the algorithms and the deployment.

    And monitoring your models for drift will help you reduce the potential for or the impact of bias and the thing is we have to, we have to be on the lookout for it.

    And we have to accept that it is going to occur and remediate it.

    And one of the big challenges that companies will run into is they will fight, tooth and nail sometimes to say that they are not biased.

    Like it’s not possible.

    Well, have you checked, right? Do you know? Have you proven that bias does or does not exist? In any of the systems and if you can’t, you’ve got a problem.

    Treat datasets, models, algorithms and, and production systems.

    guilty until proven innocent.

    When it comes to bias.

    Assume that there’s bias until you prove that there isn’t.

    If you want to have the best possible outcomes really good question.

  • Stop Using Artificial Intelligence For Human Intelligence Problems

    Stop Using Artificial Intelligence For Human Intelligence Problems

    One of the most challenging concepts to understand in machine learning and AI is machines and humans don’t think in the same way. We make the general assumption that artificial intelligence and natural intelligence function in the same way, that machines are just faster, less expensive versions of ourselves.

    In reality, our two intelligences are very, very different – and our understanding of those differences will make it easier or harder to successfully implement AI.

    Human intelligence is based on massive parallel processing. Your brain is filled with trillions of brain cells, and all joking aside, is one of the most powerful computers in existence. But the way our brains compute is fundamentally different than our silicon offspring. Our brains actually process very slowly for the most part; the nerves, chemicals, and electrical impulses in our brains individually transmit very slowly but do so in vast quantities.

    Silicon intelligence – machine intelligence – is today based on extremely fast serial processing. The largest computers have millions of processors available to them; your average laptop today has 4 or 8 processors. Those processors process information extremely quickly in binary format, turning everything into zeroes and ones.

    Imagine you have a factory, and that factory makes widgets. There are two ways to increase productivity at the factory. You can have a few workers who are extremely fast at their jobs, or you can have thousands of workers who are individually slow but extremely fast as a collective. That’s the difference between machine and human processing capabilities.

    Here’s why this matters: the kinds of problems you can solve with each type of intelligence are based on what that intelligence is good at. Computers? They can do math extremely fast, much faster than we can, because they have a few brain cells (comparatively) that are very, very fast. Math, statistics, probability, all kinds of computation – they are faster than we ever will be. But tasks that require massive parallel processing? Computers do those very slowly by comparison – and those are tasks like language, vision, hearing, etc.

    In other words, our brains are best equipped to deal with the inputs they receive from our sensory apparatus – taste, touch, smell, sound, sight. That’s not news to anyone, but when we look at the kinds of problems we try to solve with AI, the closer a problem is to a problem human intelligence excels at, the more challenging the problem will be for AI. Vision, for example, requires MASSIVE parallel processing to be able to take in all the data that makes up sight, process it, and derive meaning from it – but our brains do it easily because we devote substantial numbers of brain cells to the task.

    Conversely, the closer a problem is to what silicon intelligence excels at – computation – the more challenging the problem will be for a human. You probably can’t do fourth order derivative equations or multiple regression analysis in your head for complex problems, but machines can. Those kinds of problems are easy to distill down into zeroes and ones and crunch at insane speeds.

    Which means, as you start thinking about the implementation of AI, break down your business challenges into components and then see which category each of those components falls into. For example, if you want to boost sales, you have an entire pipeline of components – how sales reps talk to customers. How your marketing is received by customers. How your lead scoring and CRM are managed. How you forecast demand.

    Some of those components are well-suited to machines and shouldn’t be left in the hands of humans.

    Some of those components are well-suited to humans and shouldn’t be left in the hands of machines.

    This means that any company, product, or service which promises “all-inclusive” AI-powered software that will solve all your problems and be magic… won’t. By very definition, it’s going to be bad at some things, and good at others.

    If you want to see fast wins from your AI efforts, focus on those tasks that computer intelligence excels at, and start your implementation there first – then move up to the tasks that computers find harder to do well.
