The issue of bias in AI was the subject of much discussion in the AI community last week. The publication of PULSE, a machine learning model by Duke University researchers, sparked a great deal of it. PULSE proposes a new approach to the image super-resolution problem, i.e. generating a faithful higher-resolution version of a low-resolution image. In short, PULSE works by using a novel technique to efficiently search space of high-resolution artificial images generated using a GAN and identify ones that are downscale to the low-resolution image. This is in contrast to previous approaches to solving this problem, which work by incrementally upscaling the low-resolution images and which are typically trained in a supervised manner with low- and high-resolution image pairs. The images identified by PULSE are higher resolution and more realistic than those produced by previous approaches, and without the latter’s characteristic blurring of detailed areas. However, what the community quickly identified was that the PULSE method didn’t work so well on non-white input images. An example using a low res image of President Obama was one of the first to make the rounds, and Robert Ness used a photo of me to create this example: I’m going to skip a recounting of the unfortunate Twitter firestorm that ensued following the model’s release. For that background, Khari Johnson provides a thoughtful recap over at VentureBeat, as does Andrey Kurenkov over at The Gradient. Rather, I’m going to riff a bit on the idea of where bias comes from in AI systems. Specifically, in today’s episode of the podcast featuring my discussion with AI Ethics researcher Deb Raji I note, “I don’t fully get why it’s so important to some people to distinguish between algorithms being biased and data sets being biased.” Bias in AI systems is a complex topic, and the idea that more diverse data sets are the only answer is an oversimplification. Even in the case of image super-resolution, one can imagine an approach based on the same underlying dataset that exhibits behavior that is less biased, such as by adding additional constraints to a loss or search function or otherwise weighing the types of errors we see here more heavily. See AI artist Mario Klingemann’s Twitter thread for his experiments in this direction. Not electing to consider robustness to dataset biases is a decision that the algorithm designer makes. All too often, the “decision” to trade accuracy with regards to a minority subgroup for better overall accuracy is an implicit one, made without sufficient consideration. But what if, as a community, our assessment of an AI system’s performance was expanded to consider notions of bias as a matter of course? Some in the research community choose to abdicate this responsibility, by taking the position that there is no inherent bias in AI algorithms and that it is the responsibility of the engineers who use these algorithms to collect better data. However, as a community, each of us, and especially those with influence, has a responsibility to ensure that technology is created mindfully, with an awareness of its impact. On this note, it’s important to ask the more fundamental question of whether a less biased version of a system like PULSE should even exist, and who might be harmed by its existence. See Meredith Whittaker’s tweet and my conversation with Abeba Birhane on Algorithmic Injustice and Relational Ethics for more on this. A full exploration of the many issues raised by the PULSE model is far beyond the scope of this article, but there are many great resources out there that might be helpful in better understanding these issues and confronting them in our work. First off there are the videos from the tutorial on Fairness Accountability Transparency and Ethics in Computer Vision presented by Timnit Gebru and Emily Denton. CVPR organizers regard this tutorial as “required viewing for us all.” Next, Rachel Thomas has composed a great list of AI ethics resources on the fast.ai blog. Check out her list and let us know what you find most helpful. Finally, there is our very own Ethics, Bias, and AI playlist of TWIML AI Podcast episodes. We’ll be adding my conversation with Deb to it, and it will continue to evolve as we explore these issues via the podcast. I'd love to hear your thoughts on this.

How does LinkedIn allow its data scientists to access aggregate user data for exploratory analytics while maintaining its users' privacy? That was the question at the heart of our recent conversation with Ryan Rogers, a senior software engineer in data science at the company. The answer, it turns out, is through differential privacy, a topic we've covered here on the show quite extensively over the years. Differential privacy is a system for publicly sharing information about a dataset by describing patterns of groups within the dataset, the catch is you have to do this without revealing information about individuals in the dataset (privacy). Ryan currently applies differential privacy at LinkedIn, but he has worked in the field, and on the related topic of federated learning, for quite some time. He was introduced to the subject as a PhD student at the University of Pennsylvania, where he worked closely with Aaron Roth, who we had the pleasure of interviewing back in 2018. Ryan later worked at Apple, where he focused on the local model of differential privacy, meaning differential privacy is performed on individual users' local devices before being collected for analysis. (Apple uses this, for example, to better understand our favorite emojis 🤯 👍👏). Not surprisingly, they do things a bit differently at LinkedIn. They utilize a central model, where the user's actual data is stored in a central database, with differential privacy applied before the data is made available for analysis. (Another interesting use case that Ryan mentioned in the interview: the U.S. Census Bureau has announced plans to publish 2020 census data using differential privacy.) Ryan recently put together a research paper with his LinkedIn colleague, David Durfee, that they presented as a spotlight talk at NeurIPS in Vancouver. The title of the paper is a bit daunting, but we break it down in the interview. You can check out the paper here: Practical Differentially Private Top-k Selection with Pay-what-you-get Composition. There are two major components to the paper. First, they wanted to offer practical algorithms that you can layer on top of existing systems to achieve differential privacy for a very common type of query: the "Top-k" query, which means helping answer questions like "what are the top 10 articles that members are engaging with across LinkedIn?" Secondly, because privacy is reduced when users are allowed to make multiple queries of a differentially private system, Ryan's team developed an innovative way to ensure that their systems accurately account for the information the system returns to users over the course of a session. It's called Pay-what-you-get Composition. One of the big innovations of the paper is discovering the connection between a common algorithm for implementing differential privacy, the exponential mechanism, and Gumbel noise, which is commonly used in machine learning. One of the really nice connections that we made in our paper was that actually the exponential mechanism can be implemented by adding something called Gumbel noise, rather than Laplace noise. Gumbel noise actually pops up in machine learning. It's something that you would do to report the category that has the highest weight, [using what is] called the Gumbel Max Noise Trick. It turned out that we could use that with the exponential mechanism to get a differentially private algorithm. [...] Typically, to solve top-k, you would use the exponential mechanism k different times⁠ —you can now do this in one shot by just adding Gumbel noise to [existing algorithms] and report the k values that are in the the top […]which made it a lot more efficient and practical. When asked what he was most excited about for the future of differential privacy Ryan cited the progress in open source projects. This is the future of private data analytics. It's really important to be transparent with how you're doing things, otherwise if you're just touting that you're private and you're not revealing what it is, then is it really private? He pointed out the open-source collaboration between Microsoft and Harvard's Institute for Quantitative Social Sciences. The project aims to create an open-source platform that allows researchers to share datasets containing personal information while preserving the privacy of individuals. Ryan expects such efforts to bring more people to the field, encouraging applications of differential privacy that work in practice and at scale. Listen to the interview with Ryan to get the full scope! And if you want to go deeper into differential privacy check out our series of interviews on the topic from 2018.

Learn more at aka.ms/azureml. All right, onto the show! Erez Barak: [00:02:06] Thank you. Great to be here with you, Sam. Sam Charrington: [00:02:08] I'm super excited about this conversation. We will be diving into a topic that is generating a lot of excitement in the industry and that is Auto ML and the automation of the data science process. But before we dig into that, I'd love to hear how you got started working in ML and AI. Erez Barak: [00:02:30] It's a great question because I've been working with data for quite a while. And I think roughly about five to 10 years ago, it became apparent that the next chapter for anyone working with data has to weave itself through the AI world. The world of opportunity with AI is really only limited by the amount of data you have, the uniqueness of the data you have and the access you have to data. And once you're able to connect those two worlds, a lot of things like predictions, new insights, new directions, sort of come out of the woodwork. So seeing that opportunity, imagining that potential, has naturally led me to work with AI. I was lucky enough to join the Azure AI group, and there's really three focal areas within that group. One of them is machine learning. How do we enable data scientists of all skills to operate through the machine learning lifecycle, starting from the data to the training, to registering the models to putting them in productions and managing them, a process we call ML Ops. So just looking at that end to end and understanding how we enable others to really go through that process in a responsible trusted and known way has been a super exciting journey so far. Sam Charrington: [00:03:56] And so do you come at this primarily from a data science perspective, a research perspective, an engineering perspective? Or none of the above? Or all of the above? Erez Barak: [00:04:07] I'm actually going to go with all of the above. I think it'd be remiss to think that if you're  a data science perspective, and you're trying to build a product and really looking to build the right set of products for people to use as they go through their AI journey, you'd probably miss out on an aspect of it. If you just think about the engineering perspective, you'll probably end up with great info that doesn't align with any of the data science. So you really have to think between the two worlds and how one empowers the other. You really have to figure out where most data scientists of all skills need the help, want the help, are looking for tools and products and services on Azure to help them out, and I think that's the part I find most compelling. Sort of figuring that out and then really going deep where you landed, right? 'Cause if we end up building a new SDK, we're going to spend a whole lot of time with our data science customers, our data science internal teams and figure out, "Well, how should our SDK look like?" But if you're building something like Auto ML that's targeted not only at the deeper data scientist, but also the deeper rooted data professionals, you're going to spend some time with them and understand not only what they need, but also how that applies to the world of data science. Sam Charrington: [00:05:27] And what were you working on before Azure AI? Erez Barak: [00:05:31] So before Azure AI, in Microsoft, I worked for a team called Share Data, which really created a set of data platforms for our internal teams. And prior to joining Microsoft, I worked in the marketing automation space, at a company called Optify. and again the unique assets we were able to bring to the table as part of Optify in the world of marketing automations were always data based. We were always sort of looking at the data assets the marketers had and said, "what else can we get out of it?" Machine learning wasn't as prevalent at the time, but you could track back to a lot of what we did at that time and how machine learning would've helped if it was used on such a general basis. Sam Charrington: [00:06:12] Yeah, one of the first machine learning use cases that I worked with were with folks that were doing trying to do lead scoring and likelihood to buy, propensity to buy types of use cases. I mean that's been going on for a really long time. Erez Barak: [00:06:30] So we're on a podcast so you can't see me smiling, but we did a lot of work around building lead scoring...and heuristics and manual heuristics, and general heuristics, and heuristics that the customer could customize. And today, you've seen that to really evolve to a place where there's a lot of machine learning behind it. I mean, it's perfect for machine learning, right? You've got all this data. It's fresh. It's coming  in new. There's insights that are really hard to find out. Once you've start slicing and dicing it by regions or by size of customers, it gets even more interesting so all the makings for having machine learning really make it shine. Sam Charrington: [00:07:07] Yeah you are getting pretty excited I think. Erez Barak: [00:07:08] Oh, no, no, no. It's a sweet spot there. Yes. Sam Charrington: [00:07:12] Nice. You want to dive into talking about Auto ML? For the level of excitement and demand for Auto ML and enthusiasm that folks have for the topic, not to mention the amount of confusion that there is for the topic, I've probably not covered it nearly enough on the podcast. Certainly when I think of Auto ML, there's a long academic history behind the technical approaches that drive it. But it was really popularized for many with Google's Cloud Auto ML in 2018, and before that they had this New York Times PR win that was a New York Times article talking about how AI was going to create itself, and I think that contributed a lot to, 'for lack of a better term in this space', but then we see it all over the place. There are other approaches more focused on citizen data science. I'd love to just start with how you define Auto ML and what's your take on it as a space and its role and importance, that kind of thing. Erez Barak: [00:08:42] Yeah, I really relate to many of the things you touched on. So maybe I'll start - and this is true for many things we do in Azure AI but definitely for Auto ML - on your point around academic roots. Microsoft has this division called MSR, Microsoft Research, and it's really a set of researchers who look into bleeding edge topics and drive the world of research in different areas. And that is when we first got, in our team, introduced to Auto ML. So a subset of that team has been doing research around the Auto ML area for quite a few years. They've been looking at it, they've been thinking. It yes, I've heard the sentence, "AI making AI." That's definitely there. But when you start reading into it like what does it mean and to be honest, it means a lot of things to many people. It's quite overused. I'll be quite frank. There's no one industry standard definition that says, "Hmm, here's what Auto ML is." I can tell you what it is for us. I can tell you what it is for our customers. I can tell you where we're seeing it make a ton of impact. And it comes to using machine learning capabilities in order to help you, being the data scientist, create machine capabilities in a more efficient, in a more accurate, in a more structured fashion. Sam Charrington: [00:10:14] My reaction to that is that it's super high level. And it leaves the door open for all of this broad spectrum of definitions that you just talked about. For example, not to over index on what Google's been doing, but Cloud Auto ML Vision when it first came out was a way for folks to do vision cognitive services, but use some of their own data to tune it. Right? Which is a lot different. In fact, they caught a lot of flack from the academic Auto ML community because they totally redefined what that community had been working for for many years and started creating the confusion. Maybe a first question is, do you see it as being a broad spectrum of things or is it how do we even get to a definition that separates the personalized cognitive services trained with my own data versus this other set of things? Erez Barak: [00:11:30] I think you see it as more of that general sense, so I would say probably not. I see it as a much more concrete set of capabilities that adhere to a well known process. That actually is agreed upon across the industry. When you build a model, what do you do? You get data, you featurize that data. Once the features are in place, you choose a learner, you choose an algorithm. You train that algorithm with the data, creating a model. At that point, you want to evaluate the model, make sure it's accurate. You want to get some understanding of what are the underlining features that have most affected the model. And you want to make sure, in addition, that you can explain that model is not biased, you can explain that model is really fair towards all aspects of what it's looking at. That's a well-known process. I think there's no argument around that in the sort of the machine learning field that's sort of the end to end. Auto ML allows automating that process. So at its purest, you feed Auto ML the data and you get the rest for free if you may. Okay? that would be sort of where we're heading, where we want to be. And I think that's at the heart of Auto ML. So, where does the confusion start? I could claim that what we or others do for custom vision follows that path, and it does. I can also claim that some of what we do for custom vision is automated. And then there's  the short hop to say, "Well, therefore it is Auto ML." But I think that misses the general point of what we're trying to do with Auto ML. Custom vision is a great example where Auto ML can be leveraged. But Auto ML can be leveraged wherever that end to end process happens in machinery. Sam Charrington: [00:13:27] Nice. I like it. So maybe we can walk through that end to end process and talk about some of the key areas where automation is applied to contribute to Auto ML. Erez Barak: [00:13:44] So I'd like to start with featurization. And at the end of the day, we want an accurate model. A lot of that accuracy, a lot of the insights we can get, the predictions we can get, and the output we can get from any model is really hinged on how effective your featurization is. So many times you hear that, "Well, 80% of the time data scientists spend on data." Can I put a pin on, do you know where that number comes from? Oh of course. Everyone says that's the number, everyone repeats it. It's a self-fulfilling prophecy. I'm going to say 79% of it just to be sure. But I think it's more of an urban legend at that point. I am seeing customers who do spend that kind of percentages  I am seeing experiments rerun that take that amount of time. Generalizing that number is just too far now to do. Sam Charrington: [00:14:42] I was thinking about this recently, and wondering if there's some institute for data science that's been tracking this number over time. It would be interesting to see how it changes over time I think is the broader curiosity. Erez Barak: [00:14:55] It would. I should go figure that out. [laughs] So anyone who builds a model can quickly see the effect of featurization on the output. Now, a lot of what's done, when building features, can be automated. I would even venture to say that a part of it can be easily automated. Sam Charrington: [00:15:24] What are some examples? Erez Barak: [00:15:25] Some examples are like, "I want to take two columns and bring them together into one." "I want to change a date format to better align with the rest of my columns." And even a easy one, "I'd like to enhance my data with some public holiday data when I do my sales forecasting because that's really going to make it more accurate." So it's more data enhancement, but you definitely want to build features into your data to do that. So getting that right is key. Now start thinking of data sets that have many rows, but more importantly have many columns. Okay? And then the problem gets harder and harder. You want to try a lot more options. There's a lot more ways of featurizing the data. Some are more effective than others. Like we recently in Auto ML, have incorporated the BERT model into our auto featurization capability. Now that allows us to take text data we use for classification and quickly featurize it. It helps us featurize it in a way that requires less input data to come in for the model to be accurate. I think that's a great example of how deep and how far that can go. Sam Charrington: [00:16:40] You mentioned that getting that featurization right is key. To what extent is it an algorithmic methodological challenge versus computational challenge? If you can even separate these two. Meaning, there's this trade off between... Like we've got this catalog of recipes like combining columns and bending things and whatever that we can just throw at a data set that looks like it might fit. Versus more intelligent or selective application of techniques based on nuances whether pre-defined or learned about the data. Erez Barak: [00:17:28] So it extends on a few dimensions. I would say there are techniques. Some require more compute than others. Some are easier to get done. Some require a deeper integration with existing models like I mentioned BERT before, to be effective. But that's only one dimension. The other dimension is the fit of the data into a specific learner. So we don't call it experiments in machine learning for nothing. We experiment, we try. Okay? Nobody really knows exactly which features would affect the model in a proper way, would drive accuracy. So there's a lot of iteration and experimentation being done. Now think of this place where you have a lot of data, creating a lot of features and you want to try multiple learners, multiple algorithms if you may. And that becomes quickly quite a mundane process that automating can really, really help with. And then add on top of that, we're seeing more and more models created with just more and more features. The more features you have, the more nuanced you can get about describing your data. The more nuanced the model can get about predicting what's going to happen next, or we're now seeing models with millions and billions of features coming out. Now, Auto ML is not yet prepared to deal with the billion feature model, but we see that dimension extend. So extend compute, one, extend the number of iterations you would have, extend to the number of features you have. Now you got a problem that's quickly going to be referred to as mundane. Hard to do. Repetitive. Doesn't really require a lot of imagination. Automation just sounds perfect for that. So that's why one of the things we went after in the past, I'd say six to twelve months is how we get featurization to a place where you do a lot of auto featurization. Sam Charrington: [00:19:22] I'm trying to parse the extent to which, or whether, you agree with this dichotomy that I presented. You've got this mundane problem that if a human data scientist was doing would be just extremely iterative, and certainly one way of automating is to just do that iteration a lot quicker because the machine can do that. Another way of automating is... let's call it more intelligent approaches to navigating that feature space or that iteration space, and identifying through algorithmic techniques what are likely to be the right combinations of features as opposed to just throwing the kitchen sink at it and putting that in a bunch of loops. And certainly that's not a dichotomy, right? You do a bit of both. Can you elaborate on that trade off or the relationship between those two approaches? Is that even the right way to think about it or is that the wrong way to think about it? Erez Barak: [00:20:33] I think it's a definitely a way to think about it. I'm just thinking through that lens for a second. So I think you describe the brute force approach to it. On one side. The other side is how nuanced can you get about it? So what we know is you can get quite nuanced. There's things that are known to work, things that are not known to work. Things that work with a certain type of data set that don't work with another. Things that work with a certain type of data set combined with the learner that don't work with others. So as we build Auto ML, I talked about machine learning used to help with machine learning. We train a model to say, "Okay, in this kind of event, you might want to try this kind of combination first." Because if you're... I talked about the number of features, brute force is not an option. So we have have toto get a lot more nuanced about it, so what Auto ML does is given those conditions if you may, or those features for that model, it helps shape the right set of experiments before others. That's allowing you to get to a more accurate model faster. So I think that's one aspect of it. I think another aspect, which you may have touched on, and I think is really important throughout Auto ML, but definitely in featurization, is why people are excited about that. The next thing you are going to hear is that I want to see what you did. And you have to show what kind of features you used. And quickly follows is, "I want to change feature 950 out of the thousand features you gave me. And I want to add two more features at the end because I think they're important." That's where my innovation as a data scientist comes into play. So you've got to, and Auto ML allows you to do that, be able to open up that aspect and say, "Here's what I've come up with. Would you like to customize? Would you like to add? Would you like to remove?" Because that's where you as a data scientist shine and are able to innovate. Sam Charrington: [00:22:39] So we started with featurization. Next step is learner/model selection? Erez Barak: [00:22:45] I think it's probably the best next step to talk about. Yes. I think there's a lot of configuration that goes into this like how many iterations do I want to do?For instance. How accurate do I want to get? What defines accuracy? But those are more manual parameters we ask the user to add to it. But then automation again comes into play as learner selection. So putting Auto ML aside, what's going to happen? Build a set of features, choose a learner, one that I happen to know is really good for this kind of problem and try it out. See how accurate I get. If it doesn't work, but even if it works, you are going to try another. Try another few. Try a few options. Auto ML at the heart of it is what it does. Now, going to what we talked about in featurization, we don't take a brute force approach. We have a model that's been trained over millions of experiments, sort of knows what would be a good first choice given the data, given the type of features, given the type of outcome you want. What do we try first? Because people can't just run an endless number of iterations. It takes time, takes cost, and sort of takes the frankly it takes a lot of the ROI out of something you expect from Auto ML. So you want to get there as fast as possible based on learnings from the past. So what we've automated is that selection. Put in the data, set a number of iterations or not set them. We have a default number that goes in. And then start using the learners based on the environment we're seeing out there and choosing them out from that other model we've trained over time. By the way, that's a place where we really leaned on the outputs we got from MSR. That's a place where they, as they were defining Auto ML, as they were researching it, really went deep into, and really sort of created assets we were then able to leverage. A product sort of evolves over time and the technology evolves over time, but if I have to pick the most, or the deepest rooted area, we've looked at from MSR, it's definitely the ability to choose the right learner for the right job with a minimal amount of compute associated with it if you may. Sam Charrington: [00:24:59] And what are some of the core contributions of that research if you go to the layer deeper than that? Erez Barak: [00:25:10] Are you asking in context of choosing a model or in general? Sam Charrington: [00:25:13] Yeah, in the context of choosing a model. For example, as you described, what is essentially a learner, learning which model to use, that created a bunch of questions for me around like, "Okay how do you  represent this whole, what are the features of that model? And what is the structure of that model?" And I'm curious if that's something that came out of MSR or that was more from the productization and if there are specific things that came out of that MSR research that come to mind as being pivotal to the way you think about that process. Erez Barak: [00:25:57] So I recall the first version coming out of MSR wasn't really of the end to end product, but at the heart of it was this model that helps you pick learners as it relates to the type size of data you have and the type of target you have. This is where a lot of the research went into. This is where we publish papers around, "Well, which features matter when you choose that?" This is where MSR went and collected a lot of historical data around people running experiments and trained that model. So the basis at the heart of our earliest versions, we really leaned on MSR to get that model in place. We then added the workflow to it, the auto featurization I talked about, some other aspects we'll talk about in a minute, but at the heart of it, they did all that research to understand... Well, first train that model. Just grabbing the data. Sam Charrington: [00:26:54] And what does that model look like? Is it a single model? Is it relatively simple? Is it fairly complex? Is it some ensemble? Erez Barak: [00:27:06] I'll oversimplify a little bit, but it profiles your data. So it takes a profile of your data, it profiles your features, it takes a profile of your features. It looks at the kind of outcome you want to achieve. Am I doing time series forecasting here? I'm doing classification. I'm doing regression that really matters. And based on those features picks the first learner to go after. Then what it does is uses the result of that first iteration, which included all the features I'm talking about, but also now includes, "Hey, I also tried learner X and I got this result." And that helps it choose the next one. So what happens is you look at the base data you have, but you constantly have additional features that show you, "Well, what have I tried and what were the results?" And then the next learner gets picked based on that. And that gets you in a place where the more you iterate, the closer you get to that learner that gives you more accurate result. Sam Charrington: [00:28:14] So I'm hearing elements of both supervised learning. You have a bunch of experiments and the models that were chosen ultimately, but also elements of something more like simple reinforcement learning, contextual bandits, explore, exploit kind of things as well. Erez Barak: [00:28:37] It definitely does both. If I could just touch on one point, reinforcement learning, as it's defined, I wouldn't say we're doing reinforcement learning there. Saying that, we're definitely... every time we have an iteration going or every X times we have that, we do fine tune the training of the model to learn as it runs more and more. So I think reinforcement learning is a lot more reactive. But taking that as an analogy, we do sort of continuously collect more training data and then retrain the model that helps us choose better and better over time. Sam Charrington: [00:29:15] Interesting. So we've talked about a couple of these aspects of the process. Feature engineering, model selection, next is once you've identified the model, tuning hyper-parameters and optimization. Do you consider that its own step or is that a thing that you're doing all along? Or both? Erez Barak: [00:29:38] I consider it part of that uber process I talked about earlier. We're just delving into starting to use deep learning learner within Auto ML. So that's where we're also going to automate the parameter selection, hyper-parameter selection. A lot of the learners we have today are classic machine learning if you may, so that's where hyper-parameter tuning is not as applicable. But saying that, every time we see an opportunity like that, I think I mentioned earlier in our forecasting capabilities, we're now adding deep learning models. In order to make the forecasting more accurate, that's where that tuning will also be automated. Sam Charrington: [00:30:20] Okay, actually elaborate. I think we chatted about that pre-interview, but you mentioned that you're doing some stuff with TCN and Arema around times series forecasting. Can you elaborate on that? Erez Barak: [00:30:36] Yeah, so I talked about this process of choosing a learner. Now you also have to consider what is your possible set of learners you can choose from. And what we've added recently are sort of deep learning models or networks that actually are used within that process. So TCN and Arema are quite useful when doing times series forecasting. Really drive the accuracy based on the data you have. So we've now embedded those capabilities within our forecasting capability. Sam Charrington: [00:31:12] So when you say within forecasting, meaning a forecasting service that you're offering as opposed to within... Erez Barak: [00:31:21] No, let me clarify. There's three core use cases we support as part of Auto ML. One for classification, the other for regression, and the third for times series forecasting. So when I refer to that, I was referring more to that use case within Auto ML. Sam Charrington: [00:31:42] Got it. So in other words in the context of that forecasting use case, as opposed to building a system that is general and applying it to time series and using more generalized models, you're using now TCN and Arema as core to that, which are long-proven models for times series forecasting. Erez Barak: [00:32:07] Yeah, I would argue they're also a bit generalized, but in the context of forecasting. But let me tell you how we're thinking about it. There's generally applicable models. Now, we're seeing different use cases like in forecasting there are generally applicable models for that area, that are really useful in that area. That's sort of the current state we're in right now. And we want to add a lot more known generally applicable models to each area. In addition to that, sort of where we're heading and as I see this moving forward, more and more customers will want to add their own custom model. We've done forecasting for our manufacturing. We've tuned it to a place where it's just amazing for what we do because we know a lot more about our business than anyone else. We'd like to put that in the mix every time your Auto ML considers the best option. I think we're going to see- I'm already seeing a lot of that, sort of the 'bring your own model'. It makes sense. Sam Charrington: [00:33:06] That's an interesting extension to bring your own data, which was one of the first frontiers here. Erez Barak: [00:33:11] I mean you're coming in to a world now, it's not "Hey, there's no data science here. There's a lot of data science going on so I'm the data scientist. I've worked on this model for the past, you name it, weeks? Months? Years? And now this Auto ML is really going to help me be better? I don't think that's a claim we even want to make. I don't think that's a claim that's fair to make. The whole idea is find the user where they are. You have a custom model? Sure, let's plug that in. It's going to be considered with the rest in a fair and visible way, maybe with the auto featurization it even goes and becomes more accurate. Maybe you'll find out something else, you want to tune your model. Maybe you have five of those models, and you're not sure which one is best so you plug in all five. I think that's very much sort of where we're heading, plugging into an existing process that's already deep and rich wherever it lands. Sam Charrington: [00:34:07] The three areas that we've talked about, again featurization, model selection, and parameter tune or optimization are I think, what we tend to think of as the core of Auto ML. Do you also see it playing in the tail end of that process like the deployment after the model's deployed? There's certainly opportunities to automate there. A lot of that is very much related to dev ops and that kind of thing, but are there elements of that that are more like what we're talking about here? Erez Barak: [00:34:48] I think there's two steps, if you don't mind I'll talk about two steps before that. I think there's the evaluation of the model. Well, how accurate is it, right? But again you get into this world of iterations, right? So that's where automation is really helpful. That's one. The other is sort of the interpretation of the model. That's where automation really helps as well. So now, especially when I did a bunch of automation, I now want to make sure, "Well, which features really did affect this thing? Explain them to me. And work that into your automated processes. Did your process provide a fair set of data for my model to learn from? Does it represent all all genders properly? Does it represent all races properly? Does it represent all aspects of my problem, uses them in a fair way? Where do you see imbalance?" So I think automating those pieces are right before we jump into deployment, I think it's really mandatory when you do Auto ML to give that full picture. Otherwise, you're sort of creating the right set of tools, but I feel without doing that, you're sort of falling a bit short of providing everyone the right checks and balances to look at the work they're doing. So when I generalize the Auto ML process, I definitely include that. Back to your question on do I see deployment  playing there? To be honest, I'm not sure. I think definitely the way we evaluate success is we look at the models deployed with Auto ML or via Auto ML or that were created via Auto ML and are now deployed. We looked at their inferences. We look at their scoring, and we provide that view to the customer to assess the real value of their model. Automation there I think if I have to guess, yes. Automation will stretch there. Do I see it today? Can I call it that today? Not just yet. Sam Charrington: [00:36:54] Well, a lot of conversation  around this idea of deploying a model out into production, and thankfully I think we've convinced people that you can, it's not just deploy once and you're not thinking about it anymore. You have to monitor the performance of that model and there's a limited lifespan for most of the models that we're putting into production and then the next thing that folks get excited about is, "Well I can just see when my model falls out of tolerance and then auto-retrain..." It's one of these everyone's talking about it, few are actually doing it. it sounds like you're in agreement with that like we're not there yet at scale or no? Erez Barak: [00:37:42] So I think we often refer to that world as the world of ML ops. Machine learning operations in a more snappy way. I think there's a lot of automation there. If you look at automation, you do it dev ops for just code. I mean, forget machine learning code, but code, let alone models, is very much automation we need. I do think there're two separate loops that have clear interface points. Like deployed models, like maybe data about data drift. But they sort of move in different cycles at different speeds. So we're learning more about this but I suspect that iteration of training, improving accuracy, getting to a model where the data science team says, "Oh, this one's great. Let's use that." I suspect that's one cycle and frankly that's where we've been hyper-focused on automating with Auto ML. There's naturally another cycle of that, operations that we're sort of looking at automation opportunities with ML ops. Do they combine into one automation cycle? Hmm, I'm not sure. Sam Charrington: [00:38:58] But it does strike me that when for example, the decision "Do I retrain from scratch? Do I incrementally retrain? Do I start all the way over?" Maybe that decision could be driven by some patterns or characteristics in the nature of the drift in the performance shift that a model could be applied to. And then,  there're aspects of what we're thinking about and talking about as Auto ML that are applied to that dev ops-y part. Who knows? Erez Barak: [00:39:37] No, I'd say who knows. Then listening to you I'm thinking oh, to myself that while we sort of have a bit of a fixed mindset on the definition we'd definitely need to break through some of that and open up and see, "Well, what is it that we're hearing from the real world that should shape what we automate, how we automate and under which umbrella we put it?" I think, and you will notice, it's moving so fast, evolving so fast. I think we're just at the first step of it. Sam Charrington: [00:40:10] Yeah. A couple quick points that I wanted to ask about. Another couple areas that are generating excitement under this umbrella are neural architecture surge and neural evolution and techniques  like that. Are you doing anything in those domains? Erez Barak: [00:40:30] Again, we're incorporating some of those neural architectures into Auto ML today. I talked about our deeper roots with MSR and how they got us that first model. Our MSR team is very much looking deeper into those areas. They're not things that formulated just yet but the feeling is that the same concepts we put into Auto ML, or automated machine learning can be used there, can be automated there. I'm being a little vague because it is a little vague for us, but the feeling is that there is something there, and we're lucky enough to have the MSR arm that, when there's a feeling there's something there, some research starts to pan out, and they're thinking of different ideas there but to be frank, I don't have much to share at that point in terms of more specifics yet. Sam Charrington: [00:41:24] And my guess is we've been focused on this Auto ML as a set of platform capabilities that helps data scientists be more productive. There's a whole other aspect of Microsoft delivering cognitive services for vision, and other things where they're using Auto ML internally and where it's primarily deep learning based, and I can only imagine that they're throwing things like architecture surge and things like that at the problem. Erez Barak: [00:41:58] Yeah. So they do happen in many cases I think custom vision is a good example. We don't see the general patterns just yet and for the ones we do see, the means of automation haven't put out yet. So if I look at where we were with the Auto ML thinking probably a few years back is where that is right now. Meaning, "Oh, it's interesting. We know there's something there." The question is how we further evolve into something more specific. Sam Charrington: [00:42:30] Well, Erez, thanks so much for taking the time to chat with us about what you're up to. Great conversation and learned a ton. Thank you. Erez Barak: [00:42:38] Same here. Thanks for your time and the questions were great. Had a great time.

Bits and Bytes Apple hires Google’s AI head Google forms A.I. business unit. The latest in the AI talent wars, John Giannanderea, previously Google's chief of search and AI, was hired to run Apple’s “machine learning and A.I. strategy.” It’s an important victory for Apple who has lagged behind in AI. Google took the change as an opportunity to put AI into its own business unit under recent TWIML guest Jeff Dean. As the AI “arms race” intensifies, larger players are putting ever more resources into solidifying their positions. Last week we shared a similar story from Microsoft on its own reorg to better focus on AI. Researchers at MIT-IBM Watson AI Lab train models to recognize dynamic events. It’s easy for humans to recognize dynamic events, for example, opening a door, a book, or a bottle. MIT-IBM researchers hope to train models to recognize these types of dynamic events. They've released a Moments in Time dataset and are hosting a Moments in Time competition at CVPR. Note: I recently discussed similar work from the Univerisity of Montreal and startup Twenty Billion Neurons with its chief scientist Roland Memisevic.

Last week on the podcast I interviewed Clare Gollnick, CTO of Terbium Labs, on the reproducibility crisis in science and its implications for data scientists. We also got into an interesting conversation about the philosophy of data, a topic I hadn’t previously thought much about. The interview seemed to really resonate with listeners, judging by the number of comments we’ve received via the show notes page and Twitter. I think there are several reasons for this. I’d recommend listening to the interview if you haven't already. It’s incredibly informative and Clare does an excellent job explaining some of the main points of the reproducibility crisis. The short of it though is that many researchers in the natural and social sciences report not being able to reproduce each other’s findings. A 2016 “Nature” survey demonstrated that more than 70% of researchers have tried and failed to reproduce another scientist’s experiments, and more than half have failed to reproduce their own experiments. This concerning finding has far-reaching implications for the way scientific studies are performed. Gollnick suggests that one contributing factor is the idea of “p-hacking”–that is, examining one’s experimental data until patterns are found that meet the criteria for statistical significance, before determining a specific hypothesis about the underlying causal relationship. P-hacking is also known as “data fishing” for a reason: You’re working backward from your data to a pattern, which breaks the assumptions upon which statistical significance is determined in the first place. Clare points out that data fishing is exactly what machine learning algorithms do though–they work backward from data to patterns or relationships. Data scientists can thus fall victim to the same errors made by natural scientists. P-hacking in the sciences, in particular, is similar to developing overfitted machine learning models. Fortunately for data scientists, it is well understood that cross-validation, by which a hypothesis is generated on a training dataset and then tested on a validation dataset, is a necessary practice. As Gollnick points out, testing on the validation set is a lot like making a very specific prediction that’s unlikely to occur unless your hypothesis is true, which is essentially the scientific method at its purest. Beyond the sciences, there’s growing concern about a reproducibility crisis in machine learning as well. A recent blog post by Pete Warden speaks to some of the core reproducibility challenges faced by data scientists and other practitioners. Warden refers to the iterative nature of current approaches to machine and deep learning and the fact that data scientists are not easily able to record their steps through each iteration. Furthermore, the data science stack for deep learning has a lot of moving parts, and changes in any of these layers–the deep learning framework, GPU drivers, or training or validation datasets–can all impact results. Finally, with opaque models like deep neural networks, it’s difficult to understand the root cause of differences between expected and observed results. These problems are further compounded by the fact that many published papers fail to explicitly mention many of their simplifying assumptions or implementation details, making it harder for others to reproduce their work. Efforts to reproduce deep learning results are further confounded by the fact that we really don’t know why, when or to what extent deep learning works. During an award acceptance speech at the 2017 NIPS conference, Google’s Ali Rahimi likened modern machine learning to alchemy for this reason. He explained that while alchemy gave us metallurgy, modern glass making, and medications, alchemists also believed they could cure illnesses with leeches and transmute base metals into gold. Similarly, while deep learning has given us incredible new ways to process data, Rahimi called for the systems responsible for critical decisions in healthcare and public policy to be “built on top of verifiable, rigorous, thorough knowledge.” Gollnick and Rahimi are united in advocating for a deeper understanding of how and why the models we use work. Doing so might mean a trip back to basics–as far back as the foundations of the scientific method. Gollnick mentioned in our conversation that she’s been fascinated recently with the “philosophy of data,” that is, the philosophical exploration of scientific knowledge, what it means to certain of something, and how data can support these. It stands to reason that any thought exercise that forces us to face tough questions about issues like explainability, causation, and certainty, could be of great value as we broaden our application of modern machine learning methods. Guided by the work of science philosophers like Karl Popper, Thomas Kuhn, and as far back as David Hume, this type of deep introspection into our methods could prove useful for the field of AI as a whole. What do you think? Does AI have a reproducibility crisis? Should we bother philosophizing about the new tools we’ve made, or just get to building with them?

Bits and Bytes Last week I attended the GTC - GPU Technology Conference in San Jose. NVIDIA made quite a few announcements so you’ll see quite a few of those in this week’s news run down. Microsoft speeds neural net inference with Project Brainwave. Microsoft Research’s Project Brainwave uses Intel FPGAs to accelerate deep learning inference. The company reports that the system has been deployed for Bing, the search engine, resulting in 10x reductions in inference latency while accommodating a 10x increase in model size. Google launches text-to-speech service for developers. Cloud Text-to-Speech offers 32 different voices from 12 languages and variants. It includes a selection of voices built using WaveNet, a generative model for raw audio created by DeepMind. Microsoft reshuffles to bring more AI into products. With AI competition heating up industry-wide, Microsoft is looking to position itself as a leader in the AI solutions and developer markets. The company will now be split into “Experiences & Devices,” “Cloud + AI Platform,” and the existing branch of Microsoft Research. NVIDIA and Arm partner bring deep learning to IoT devices. NVIDIA and Arm will integrate the former’s open-source Deep Learning Accelerator architecture into the latter’s Project Trillium processors for machine learning inference.

Healthcare applications of machine learning and AI have been in the news a bit more than usual recently, concurrent with the recent HiMSS conference in Las Vegas. HiMSS is a 45,000+ attendee conference dedicated to healthcare IT. Surprising no one, AI was a major factor at this year’s event. There was a whole subconference focused on ML & AI, plus a ton of AI-focused sessions in the regular conference and a good number of announcements by industry leaders and startups alike. I’ve only done a couple of healthcare-focused shows on the podcast so far, but I’m planning to dive into this area more deeply this year. Healthcare is arguably one the most promising–not to mention important–areas of AI application. Progress is being made across a good many areas, including: Radiology. Image-based diagnostics like radiology lend themselves to the application of deep learning. There are large amounts of labeled image data to work from and a degree of uniformity that's unmatched in many other vision applications. There’s been a raft of research papers on the application of deep learning to radiology and a lot of speculation about AI eventually replacing radiologists, but also strong arguments against this ever happening. Diagnostics. Radiology aside, machine learning and AI has the potential to help doctors make better diagnostic calls. One company that’s been active in this space is the startup Enlitic. The company–which at one time was lead by Fast.ai founder and former Kaggle president Jeremy Howard–wants to use deep learning to help make diagnostic calls, manage patient triage and screening programs, and identify high-level population health trends. Google Brain, Google DeepMind, and IBM Watson are all very active in this area as well, among others; the first of these recently published interesting research into the use of deep learning to predict cardiovascular diseases using retinal images, as opposed to more invasive blood tests. Health Monitoring. Machine learning is also driving health diagnostics and monitoring into the hands of consumers. Last year Apple unveiled a research study app that uses Apple Watch’s built-in heart rate monitor to collect data on irregular heartbeats and alert patients who may be experiencing atrial fibrillation. FirstBeat, a supplier to other fitness watch makers, uses machine learning to predict wearer’s stress levels and recovery times. I spoke with Ilkka Korhonen, the company’s vice president of technology about physiology-based models for fitness and training earlier this year. Personalized medicine. Personalized, or precision, medicine seeks to tailor medical interventions to the predicted response of the patient based on their genetics or other factors. Applications include selecting the best medicines for each patient and developing custom medications that target pathways based on an individual patient’s genetics. My interview with Brendan Frey of Toronto-based Deep Genomics explored a few of the opportunities in this space. Deep Genomics is working on “biologically accurate” artificial intelligence for developing new therapies. Electronic Health Records. The major EHR vendors–including Allscripts, Athenahealth, Cerner, eClinicalWorks, and Epic–all made announcements at HiMSS about ways that they would be incorporating AI into their products. Allscripts announced a partnership with Microsoft to develop an Azure-powered EHR, while Epic unveiled a partnership with Nuance to integrate their AI-powered virtual assistant into the Epic EHR workflow. Trump Administration advisor Jared Kushner even made an appearance advocating for greater EHR interoperability as a step towards applying AI, machine learning, and big data. Surgery. Researchers are beginning to incorporate AI into the planning and execution of a variety of surgical procedures. A variety of surgical scenarios have been explored, including burn care, limb transplants, craniofacial surgery, cancer treatment, and aesthetic (plastic) surgery. Of course, significant obstacles remain before we see AI fully integrated into healthcare delivery. Naturally, the barrier to releasing new products in healthcare is much higher than other industries since even small mistakes can have life-threatening consequences for patients. The techniques being applied now in research must be made more robust, a clear chain of accountability must be present, and justification for how why and how care decisions are made must be made clear. Improving robustness and performance will require time, a lot of data, and many rounds of testing. Increasing trust will further require new tools and techniques for explaining opaque algorithms like deep learning (the aforementioned Google research using retinal images provides a good example of this). We won’t see the autonomous robo-doctors of science fiction anytime soon, but machine learning and AI will undoubtedly play a significant role in the experience of healthcare consumers and providers in the years to come.
