ALL RIGHTS RESERVED. To take one example, experiments that I did on predecessors to deep learning, first published in 1998, continue to hold validity to this day, as shown in recent work with more modern models by folks like Brendan Lake and Marco Baroni and Bengio himself. Some people liked the tweet, some people didn’t. the Symbols won’t cut it on their own, and deep learning won’t either. Instead, he seemed (to me) be making a suggesting for how to map hierarchical sets of symbols onto vectors. 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. automation also Here’s the tweet, perhaps forgotten in the storm that followed: For the record and for comparison, here’s what I had said almost exactly six years earlier, on November 25, 2012, eerily similar. Gary Marcus (@GaryMarcus), the founder and chief executive of Robust AI, and Ernest Davis, a professor of computer science at New York University, are the authors of … That’s really telling. Deep learning is, like anything else we might consider, a tool with particular strengths, and particular weaknesses. While human-level AIis at least decades away, a nearer goal is robust artificial intelligence. But it is not trivial. in So deep learning emerged as a very rough, very broad way to distinguish a layering approach that makes things such as AlexNet work.Â. (“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. Edge Davies's complaint is that back-prop is unlike human brain activity, arguing "it's really an optimization procedure, it's not actually learning."Â. Click here for abstracts. These models cannot generalize outside the training space. But the tweet (which expresses an argument I have heard many times, including from Dietterich more than once) neglects the fact we also do have a lot of strong suggestive evidence of at least some limit in scope, such as empirically observed limits reasoning abilities, poor performance in natural language comprehension, vulnerability to adversarial examples, and so forth. The technical issue driving Alcorn’s et al’s new results? I think — and I am saying this for the public record, feel free to quote me — deep learning is a terrific tool for some kinds of problems, particularly those involving perceptual classification, like recognizing syllables and objects, but also not a panacea. digital technology. In the meantime, as Marcus suggests, the term deep learning has been so successful in the popular literature that it has taken on a branding aspect, and it has become a kind-of catchall that can sometimes seem like it stands for anything. The same kind of heuristic use of deep learning started to happen with Bengio and others around 2006, when Geoffrey Hinton offered up seminal work on neural networks with many more layers of computation than in past. 2U The form of the argument was to show that neural network models fell into two classes, those (“implementational connectionism”) that had mechanisms that formally mapped onto the symbolic machinery of operations over variables, and those (“eliminative connectionism”) that lacked such mechanisms. of projects I’m not saying I want to forget deep learning. In fact, it’s worth reconsidering my 1998 conclusions at some length. in If our dream is to build machine that learn by reading Wikipedia, we ought consider starting with a substrate that is compatible with the knowledge contained therein. units, Japan's clinical Please review our terms of service to complete your newsletter subscription. efficiency, It worries me, greatly, when a field dwells largely or exclusively on the strengths of the latest discoveries, without publicly acknowledging possible weaknesses that have actually been well-documented. 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. Panel discussion incl. Or something in between? factors AI and deep learning have been subject to a huge amount of hype. Deep learning is important work, with immediate practical applications. Bengio's response implies he doesn't much care about the semantic drift that the term has undergone because he's focused on practicing science, not on defining terms. Nobody should be surprised by this. If we want to stop confusing snow plows with school buses, we may ultimately need to look in the same direction, because the underlying problem is the same: in virtually every facet of the mind, even vision, we occasionally face stimuli that our outside the domain of training; deep learning gets wobbly when that happens, and we need other tools to help. Realistically, deep learning is only part of the larger challenge of building intelligent machines. So the topic of branding is in some sense unavoidable. In a new paper, Gary Marcus argues there's been an “irrational exuberance” surrounding deep learning 5nm That’s actually a pretty moderate view, giving credit to both sides. that the idea that deep learning is overhyped is itself overhyped, Hinton, for example, gave a talk at Stanford in 2015 called Aetherial symbols, like Anish Athalye’s carefully designed, 3-d printed foam covered dimensional baseball that was mistaken for an espresso, dubiously likened the noncanonical pose stimuli to Picasso painting, e chief reason motivation I gave for symbol-manipulation, back in 1998, When to use Reinforcement Learning (and when not to), Processing data for Machine Learning with TensorFlow, Authorship Attribution through Markov Chain, Simple Monte Carlo Options Pricer In Python, Training an MLP from scratch using Backpropagation for solving Mathematical Equations, Camera-Lidar Projection: Navigating between 2D and 3D, A 3 step guide to assess any business use-case of AI, Sentiment Analysis on Movie Reviews with NLP Achieving 95% Accuracy. find as to advances, The recent paper, by scientist, author and entrepreneur, Gary Marcus, on the next decade of AI is highly relatable to the endeavor of AI/ML practitioners to deliver a stable system using a technology that is considered brittle. 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. The secondary goal of the book was to show that that was possible to build the primitives of symbol manipulation in principle using neurons as elements. where infrastructure Gary F. Marcus's 103 research works with 4,862 citations and 8,537 reads, including: Supplementary Material 7 process In the ultimate solution to AI. No less predictable are the places where there are fewer advances: in domains like reasoning and language comprehension — precisely the domains that Bengio and I are trying to call attention to — deep learning on its own has not gotten the job down, even after billions of dollars of investment. Insisting that a system optimizes along some vector is a position that not everyone agrees with.
