(“Our results comprehensively demonstrate that a pure [deep] reinforcement learning approach is fully feasible, even in the most challenging of domains”) — without acknowledging that other hard problems differ qualitatively in character (e.g., because information in most tasks is less complete than it is Go) and might not be accessible to similar approaches. From Yoshua Bengio's slides for the AI debate with Gary Marcus, December 23rd. Yesterday's Learning Salon with Gary Marcus. This account provides a straightforward framework for understanding how universals are extended to arbitrary novel instances. processes Far more researchers are more comfortable with vectors, and every day make advances in using those vectors; for most researchers, symbolic expressions and operations aren’t part of the toolkit. To take another example, consider LeCun, Bengio and Hinton’s widely-read 2015 article in Nature on deep learning, which elaborates the strength of deep learning in considerable detail. Why continue to exclude them? I had said almost exactly six years earlier, on November 25, 2012, Deep Learning: A Critical Appraisal article, just woken up to the utility of deep learning. Machine learning (ML) has seen a tremendous amount of recent success and has been applied in a variety of applications. That’s really telling. Companies with "deep" in their name have certainly branded their achievements and earned hundreds of millions for it. 5G https://medium.com/@Montreal.AI/transcript-of-the-ai-debate-1e098eeb8465 AI The most important question that I personally raised in the Twitter discussion about deep learning is ultimately this: “can it solve general intelligence? on AWS' custom chip family expands, launches Trainium for machine learning models. cities That could be a loss function, or an energy function, or something else, depending on the context.Â, In fact, Bengio and colleagues have argued in a recent paper that the notion of objective functions should be extended to neuroscience. Gary F. Marcus's 103 research works with 4,862 citations and 8,537 reads, including: Supplementary Material 7 systems … use techniques like deep learning as just one element in a very complicated ensemble of techniques, ranging from the statistical technique of Bayesian inference to deductive reasoning. to ¹ Thus Spake Zarathustra, Zarathustra’s Prologue, part 3. I’m not saying I want to forget deep learning. advances, Hence, the current debate will likely not go anywhere, ultimately.Â, Monday night's debate found Bengio and Marcus talking about similar-seeming end goals, things such as the need for "hybrid" models of intelligence, maybe combining neural networks with something like a "symbol" class of object. I stand by that — which as far as I know (and I could be wrong) is the first place where anybody said that deep learning per se wouldn’t be a panacea, and would instead need to work in a larger context to solve a certain class of problems. And although symbols may not have a home in speech recognition anymore, and clearly can’t do the full-stack of cognition and perception on their own, there’s lot of places where you might expect them to be helpful, albeit in problems that nobody, either in the symbol-manipulation-based world of classical AI or in the deep learning world, has the answers for yet — problems like abstract reasoning and language, which are, after all the domains for which the tools of formal logic and symbolic reasoning are invented. And it’s where we should all be looking: gradient descent plus symbols, not gradient descent alone. says Privacy Policy | What I was saying in 2012 (and have never deviated from) is that deep learning ought to be part of the workflow for AI, not the whole thing (“just one element in a very complicated ensemble of things”, as I put it then, “not a universal solvent, [just] one tool among many” as I put it in January). Marcus is Founder and CEO of Robust.AI and a professor emeritus at NYU. The reader can judge for him or herself, but the right hand column, it should be noted, are all natural images, neither painted nor rendered; they are not products of imagination, they are reflection of a genuine limitation that must be faced. By reflecting on what was and wasn’t said (and what does and doesn’t actually check out) in that debate, and where deep learning continues to struggle, I believe that we can learn a lot. In my 2001 book The Algebraic Mind, I argued, in the tradition of Newell and Simon, and my mentor Steven Pinker, that the human mind incorporates (among other tools) a set of mechanisms for representing structured sets of symbols, in something like the fashion of a hierachical tree. The best conclusion: @blamlab AI is the subversive idea that cognitive psychology can be formalized. Symbols won’t cut it on their own, and deep learning won’t either. I think it is far more likely that the two — deep learning and symbol-manipulation-will co-exist, with deep learning handling many aspects of perceptual classification, but symbol-manipulation playing a vital role in reasoning about abstract knowledge. Humans can generalize a wide range of universals to arbitrary novel instances. The process of attaching y to a specific value (say 5) is called binding; the process that combines that value with the other elements is what I would call an operation. MIT appear account The central claim of the book was that symbolic processes like that — representing abstractions, instantiating variables with instances, and applying operations to those variables, was indispensible to the human mind. LouAnn Gerken, Sharon Goldwater, Noah Goodman, Gary Marcus, Rebecca Saxe, Josh Tenenbaum, Ed Vul, and three anonymous re-viewers for valuable discussion. Insisting that a system optimizes along some vector is a position that not everyone agrees with. In a new paper, Gary Marcus argues there's been an “irrational exuberance” surrounding deep learning teams Semantic Scholar profile for G. Marcus, with 411 highly influential citations and 128 scientific research papers. Whatever one thinks about the brain, virtually all of the world’s software is built on symbols. We are extremely grateful to Douglas Summers-Stay for running the experiments; we were unable to run them ourselves because AIOpen refused to give us access to the program. are to explicitly Last week, for example, Tom Dietterich said (in answer to a question about the scope of deep learning): Dietterich is of course technically correct; nobody yet has delivered formal proofs about limits on deep learning, so there is no definite answer. I think we need to consider the hard challenges of AI and not be satisfied with short-term, incremental advances. The idea goes back to the earliest days of computer science (and even earlier, to the development of formal logic): symbols can stand for ideas, and if you manipulate those symbols, you can make correct inferences about the inferences they stand for.
