Can connectionism save constructivism? arXiv. IBM, number 39 on our list of the 50 Smartest Companies, overhyped its Watson machine-learning system, … My main criticism for his Machine Learning course (but not his Deep Learning courses) is that it is done in Octave, which I feel is outdated, and I feel Python would have been a better choice — just like it’s done in his Deep Learning specializatio One favorite among the papers I failed to cite is Shanahan’s Deep Symbolic Reinforcement (Garnelo, Arulkumaran, & Shanahan, 2016); I also can’t believe I forgot Richardson and Domingos’ (2006) Markov Logic Networks. 4. “One thing that I don’t understand. — @GaryMarcus says that DL is not good for hierarchical structures. 2. Marcus, G. F. (1998b). Pets and fish are probably counted in those 50,000; pet fish, which is something different, probably isn’t counted. 6. Cognitive scientists generally place the number of atomic concepts known by an individual as being on the order of 50,000, and we can easily compose those into a vastly greater number of complex thoughts. Realistically, deep learning is only part of the larger challenge of building intelligent machines. All are making some progress here; some of these even include deep learning, but they also all include structured representations and operations over variables among their primitive operations; that’s all I am asking for. That’s fine for some purposes, but not others. 7. (2017). Takes risks instead of Humans. Come on! Banks should review the loans they’ve already made in order to mitigate charge-offs due to changes in the economy. And Google Search certainly takes in data and knowledge and processes them hierarchically (which according to Maher Ibrahim is all you need to count as being deep learning). And Forbus and Gentner’s (Falkenhainer, Forbus, & Gentner, 1989) and Hofstadter and Mitchell’s (1994) work on analogy; and many others. and 2, 4, 6 ….? Machine learning will always be more powerful than traditional methods because it uses more data and better math, but you can’t assume that ML will cover up for sloppy modeling or loose model risk management practices. Vision is not as solved as many people seem to think. Hinton, Bengio… are openly going for a model of human intelligence.”, Second prize goes to a math PhD at Google, Jeremy Kun, who countered the dubious claim that “General AI is not the goal of deep learning” with “If that’s true, then deep learning experts sure let everyone believe it is without correcting them.”. I haven’t just been advocating for it, I’ve actually been working on it … you are well aware of this, but it doesn’t transpire [sic] in your paper.”. In 2018, Forbesreported “With false positive rates sometimes exceeding 90%, something is awry with most banks’ legacy compliance processes to fight financial crimes such as money laundering.” Such high false positive rates force investigators to waste valuable time and resources working through large alert queues, performing needless investigations, and reconciling disparate data … Systems are opaque, making them very hard to debug. If we want to get to AGI, we have to solve the problem. Third, the claim that no current system can extrapolate turns out to be, well, false; there are already ML systems that can extrapolate at least some functions of exactly the sort I described, and you probably own one: Microsoft Excel, its Flash Fill function in particular (Gulwani, 2011). The child language data I gathered (Marcus et al., 1992) for my dissertation have been cited hundreds of times, and were the most frequently-modeled data in the 90’s debate about neural networks and how children learned language. Re: hierarchy, what about Socher’s tree-RNNs? It is capable of machine learning as well as pattern recognition. In The Algebraic Mind I referred to this specific kind of extrapolation as generalizing universally quantified one-to-one mappings outside of a space of training examples. In any event, I would not equate deep learning and differentiable programming (e.g., approaches that I cited like neural Turing machines and neural programming). It’s really more of a hybrid, with important components that are driven by symbol-manipulating algorithms, along with a well engineered deep-learning component. The second part is more substantive. (In some sense, Dieterrich proposed this objection later in his tweet stream.). 12. Advances in connectionist and neural computation theory, 2(31–112)(31–112), 29–30. arXiv preprint arXiv:1206.3255. Several recent works frame the problem as that of algorithmic fairness, a framework that has attracted considerable attention and criticism. A lot of them though, would not really count as AGI, which was the main focus of my paper. If you are a human, you might think of the function as something like “reversal”, easily expressed in a line of computer code. Performance cannot be audited or guaranteed at the ‘long tail’. (Convolution is a way of building in one particular such mapping, prior to learning). Dietterich, made essentially the same point, more concisely: “Marcus complains that DL can’t extrapolate, but NO method can extrapolate.”. Nature, 538(7626)(7626), 471–476. Quoting from the abstract, the paper “analyzes the transferability of deep representations from Web images to robotic data [in the wild]. Rethinking eliminative connectionism. 7. If you replaced every transistor in a classic symbolic microprocessor with a neuron, but kept the chip’s logic entirely unchanged, a true deep learning acolyte would still declare victory. Frequently Asked Questions for: The Atoms of Neural Computation. Pengfei et al (2017) offers some interesting discussion. Church: a language for generative models. Marcus has no standing in the field; he isn’t a practitioner; he is just a critic. It intended to simulate the behavior of biological systems composed of “neurons”. Marcus, G. F., Vijayan, S., Bandi Rao, S., & Vishton, P. M. (1999). The Birth of the Mind : how a tiny number of genes creates the complexities of human thought. so far, each paradigm has tended to dominate for about a decade before losing prominence (e.g., neural networks dominated in the 80s, Bayesian learning in the 90s, and kernel methods in the 2000s). Putting all this very differently, one crude way to think about where we are with most ML systems that we have today [Note 7] is that they just aren’t designed to think “outside the box”; they are designed to be awesome interpolators inside the box. For example, in reading a draft of this paper, Melanie Mitchell pointed me to important recent work by Loghmani and colleague (2017) on assessing how deep learning does in the real world. Input Monitoring. I see this as a good trend, and one potential way to begin to address the spoofing problem, but also as a reflection of trouble with the standard deep learning approach. But it’s not like I didn’t say any. They encode correlation, not causation or … Boston : Houghton Mifflin. The current unprecedented economic environment, with sharply rising unemployment claims, volatile stocks and bonds, and decreased consumer spending due to widespread shelter-in-place orders, is not represented in any historical dataset. Because I think clarity around these issues is so important, I’ve compiled a list of fourteen commonly-asked queries. You could have been more critical of deep learning. If integrating all this stuff into deep learning is what gets us to AGI, my conclusion, quoted below, will have turned out to be dead on: To the extent that the brain might be seen as consisting of “a broad. Do not learn incrementally or interactively, in real time. As co-founder and CEO I put together a team of some of the very best machine learning talent in the world, including Zoubin Ghahramani, Jeff Clune, Noah Goodman, Ken Stanley and Jason Yosinski, and played a pivotal role in developing our core intellectual property and shaping our intellectual mission.
