      Many people sharing this essay arguing that "computational scale beats clever new ideas". It takes for granted backprop, better activation functions, better learning methods, conv nets, better regularization techniques, etc etc. In other words, it seems to ignore the clever ideashttps://twitter.com/gdb/status/1106329741785653248 …

      From Richard Sutton (http://incompleteideas.net/ ), an essay on the repeated historical finding that computational scale has always beaten cleverness in AI (and some commentary on why this is such a hard-to-accept fact): http://www.incompleteideas.net/IncIdeas/BitterLesson.html …

      An example is this argument that Deep Blue was just massive search. It wasn't: it used more than 8,000 hand-engineered features that incorporated a huge amount of chess knowledge. Contrast Sutton's essay on the left with the paper about Deep Blue on the right:pic.twitter.com/xyFQJH7LL9

      Of course, I don't disagree at all with the essay that computational scale buys you an incredible amount, and it's easy to under-estimate. But GANs & levering pawns (etc) weren't discovered with computational scale.

      Nice followup from @gdb, making the point that it's a false dichotomy (scale versus cleverness):https://twitter.com/gdb/status/1106386231338762240 …

      Both are important! Look at GPT-2 for instance — that's a general-purpose architectural improvement (i.e. the Transformer) run at massive scale. One interesting point from the essay is that scale gets a bad rap — doing the reverse isn't a good way of fixing the problem!

      A better essay collecting some (correct!) examples in the same general direction is this paper by Banko & Brill: http://www.aclweb.org/anthology/P01-1005 … See eg this great graph, showing performance as a function of training data size. In this example: more data >> smarter algorithmpic.twitter.com/zwEmQSGMcP

      There is, IMO, a good paper to be written following this up, carefully understanding the relationship between scale and clever ideas.

      The Banko & Brill paper helped catalyse the 'big data' hype, but few people have shared the many examples where the opposite is true (i.e. where more data doesn't really help at all).

      Yeah - it'd be nice to have a whole bundle of examples fleshing this out carefully, and collected up in one place.
