On the whole I agree, but having read "Reinforcement Learning: An Introduction" by him and Barto, this article comes across as a hardly nuanced self-endorsement of RL as "the inevitable future of AI". Without mentioning RL by name (but hinting at it with HMM, search&learning- like exploration&exploitation), I think he might be suggesting that any supervised learning is still too specific. Not to mention that he works for DeepMind, which has found fruitful applications of RL.

I think this bitter lesson needs to be taken for a several grains of salt. Number one, the progress in a particular AI field tends to go, at first, from custom to more general algorithms, exactly as Professor Richard Sutton described. However, there is a second part to this progress, where, once we "understood" (which we never really do) the new level of general algorithms (say Transformers in NLP), we begin to put b…

I don’t follow your critique for #2. SVMs, Random forests, etc., aren’t the counterexample to Rich’s post (for anyone who knows him, Rich doesn’t even particularly _like_ neural networks). The counterexample is hand crafted features. A counter example would be showing a number of successful examples in, say, computer vision, where handcrafted features do better than learned features. This is largely not the case. In,…

Thank you for the good point! I edited the comment.

I think there's also a challenging line to draw about where a defining a search space stops and where encoding knowledge begins. When you define attention modules for an LLM, encode a search heuristic into A*, or define a feature space for a random forest, you are encoding domain knowledge, i.e. adding bias in exchange for faster learning relative to an even more general model. At any given time, the best performing computation heavy techniques have embedded more structural knowledge than zero, while much less than some experts believed necessary.

> [the critics of brute force] said that ``brute force" search may have won this time, but it was not a general strategy, and anyway it was not how people played chess. No expert in AI or chess, but I assume that this observation is wrong. Chess players do indeed construct moves based on a search of an interior mental library... a sort of pattern recognition. Any chess players here agree/disagree? As an artist who is…

"Eventually AI will start using other AI art as reference, and will dissolve into a sort of 'Lorem ipsum' state: an impression of sense without sense. Indeed, it might be argued that to a degree this has already happened."

The AI art on the internet is (in most cases) cherry-picked, and therefore reasonable fodder for further training.

I'm shocked there's so much push back on this here. This was written in 2019 but it applies even more so today. All the recent advances in AI for the past decade have, as a base requirement, massive amounts of compute. Not a proof but it should be a big red flag that if you don't believe Sutton, you should maybe consider.

Put it this way. Do you believe premature optimization is the root of all evil? Then why do you believe that some subtle, intricate optimization for machine intelligence will win out over brute compute force? It's not that there's optimizations to be done, it's knowing what optimizations will yield the most value after the space is explored with better computing capabilities.

To me, this is almost like a generalized "Proebstings Law" [0], where compiler optimizations give a doubling every 18 years compared, to say, some type of generalized Moore's law which give roughly a doubling in compute every 1.5 to 2 years.

Natural selection is a massive amount of computation. It's not like we got to skip that. Any learning that we do without computation is based on structures that were computed by evolution. One way or another the "learning" process is happening somewhere.
