michael jordan reddit machine learning

As for the next frontier for applied nonparametrics, I think that it's mainly "get real about real-world applications". Anything that the brain couldn't do was to be avoided; we needed to be pure in order to find our way to new styles of thinking. I had this romantic idea about AI before actually doing AI. E.g., (1) How can I build and serve models within a certain time budget so that I get answers with a desired level of accuracy, no matter how much data I have? ), there is still lots to explore in PGM land. But one shouldn't definitely not equate statistics or optimization with theory and machine learning with applications. Once more courage for real deployment begins to emerge I believe that the field will start to take off. Like all these thousands of papers that get published every year, where they just slightly change their training methodology/objective function/whatever, make a demo how this gives you 2% performance increase in some scenarios, come up with a catchy acronym for it and then pass it off as original research. Useful links. My first and main reaction is that I’m totally happy that any area of machine learning (aka, statistical inference and decision-making; see my other post :-) is beginning to make impact on real-world problems. Also, note that the adjective "completely" refers to a useful independence property, one that suggests yet-to-be-invented divide-and-conquer algorithms. Over the past 3 years we've seen some notable advancements in efficient approximate posterior inference for topic models and Bayesian nonparametrics e.g. There's still lots to explore there. Very challenging problems, but a billion is a lot of money. Also I rarely find it useful to distinguish between theory and practice; their interplay is already profound and will only increase as the systems and problems we consider grow more complex. RL is far from solved in general, but it's obvious that that tools that are going to solve it are going to grow out of deep learning tools. I might add that I was a PhD student in the early days of neural networks, before backpropagation had been (re)-invented, where the focus was on the Hebb rule and other "neurally plausible" algorithms. But this mix doesn't feel singularly "neural" (particularly the need for large amounts of labeled data). I am an apologist for computational probability in machine learning because I believe that probability theory implements these two principles in deep and intriguing ways — namely through factorization and through averaging. (7) How do I do some targeted experiments, merged with my huge existing datasets, so that I can assert that some variables have a causal effect? (5) How can I do diagnostics so that I don't roll out a system that's flawed or so that I can figure out that an existing system is now broken? I don't expect anyone to come to Berkeley having read any of these books in entirety, but I do hope that they've done some sampling and spent some quality time with at least some parts of most of them. He has been named a Neyman Lecturer and a Medallion Lecturer by the Institute of Mathematical Statistics. On linear stochastic approximation: Fine-grained Polyak-Ruppert and non-asymptotic concentration.W. outside of quant finance and big tech very few companies/industries can use machine learning properly. I do think that Bayesian nonparametrics has just as bright a future in statistics/ML as classical nonparametrics has had and continues to have. He is one of the leading figures in machine learning, and in 2016 Science reported him as the world's most influential computer scientist. There are still many challenges to solve in this space, and a wide variety of them, many of which aren't even being considered or worse are being described as not even a challenge. Great questions, particularly #1. It seems short sighted. Do you still think this is the best set of books, and would you add any new ones? (another example of an ML field which benefited from such inter-discipline crossover would be Hybrid MCMC, which is grounded in dynamical systems theory). I'd also include B. Efron's "Large-Scale Inference: Empirical Bayes Methods for Estimation, Testing, and Prediction", as a thought-provoking book. But what else would you expect? That's a useful way to capture some kinds of structure, but there are lots of other structural aspects of joint probability distributions that one might want to capture, and PGMs are not necessarily going to be helpful in general. My colleague Yee Whye Teh and I are nearly done with writing just such an introduction; we hope to be able to distribute it this fall. The "statistics community" has also been very applied, it's just that for historical reasons their collaborations have tended to focus on science, medicine and policy rather than engineering. That particular version of the list seems to be one from a few years ago; I now tend to add some books that dig still further into foundational topics. We have a similar challenge---how do we take core inferential ideas and turn them into engineering systems that can work under whatever requirements that one has in mind (time, accuracy, cost, etc), that reflect assumptions that are appropriate for the domain, that are clear on what inferences and what decisions are to be made (does one want causes, predictions, variable selection, model selection, ranking, A/B tests, etc, etc), can allow interactions with humans (input of expert knowledge, visualization, personalization, privacy, ethical issues, etc, etc), that scale, that are easy to use and are robust. That said, I've had way more failures than successes, and I hesitate to make concrete suggestions here because they're more likely to be fool's gold than the real thing. I had the great fortune of attending your course on Bayesian Nonparametrics in Como this summer, which was a very educational introduction to the subject, so thank you. Here’s how to get started with machine learning algorithms: Step 1: Discover the different types of machine learning algorithms. That's the old-style neural network reasoning, where it was assumed that just because it was "neural" it embodied some kind of special sauce. Thank you for taking the time out to do this AMA. Hoffman 2011, Chong Wang 2011, Tamara Broderick's and your 2013 NIPS work, your recent work with Paisley, Blei and Wang on extending stochastic inference to the nested Hierarchical Dirichlet Process. Most of what is labeled AI today, particularly in the public sphere, is actually machine learning (ML), a term in use for the past several decades. That list was aimed at entering PhD students at Berkeley,who I assume are going to devote many decades of their lives to the field, and who want to get to the research frontier fairly quickly. This made an impact on me. https://www.youtube.com/watch?v=4inIBmY8dQI. I had this romantic idea about AI before actually doing AI. On the other hand, despite having limitations (a good thing! What I mostly took away from this is that many of the things he says AI can't do fall into the same bucket of 'AI cannot do reasoning'. Machine learning is about machine learning algorithms. Indeed I've spent much of my career trying out existing ideas from various mathematical fields in new contexts and I continue to find that to be a very fruitful endeavor. Why does anyone think that these are meaningful distinctions? These are a few examples of what I think is the major meta-trend, which is the merger of statistical thinking and computational thinking. In the topic modeling domain, I've been very interested in multi-resolution topic trees, which to me are one of the most promising ways to move beyond latent Dirichlet allocation. I've personally been doing exactly that at Berkeley, in the context of the "RAD Lab" from 2006 to 2011 and in the current context of the "AMP Lab". You need to know what algorithms are available for a given problem, how they work, and how to get the most out of them. Decision trees, nearest neighbor, logistic regression, kernels, PCA, canonical correlation, graphical models, K means and discriminant analysis come to mind, and also many general methodological principles (e.g., method of moments, which is having a mini-renaissance, Bayesian inference methods of all kinds, M estimation, bootstrap, cross-validation, EM, ROC, and of course stochastic gradient descent, whose pre-history goes back to the 50s and beyond), and many many theoretical tools (large deviations, concentrations, empirical processes, Bernstein-von Mises, U statistics, etc). A "statistical method" doesn't have to have any probabilities in it per se. I think that that's true of my students as well. , topic modelling, and M. I.
