Ali Rahimi's talk at NIPS(NIPS 2017 Test-of-time award presentation)

I'm also an AI researcher and I'm not hopeful that the hype will die down anytime soon. People have been touting insignificant results through shoddy science for a long time now. They've noticed it works well enough because current ML is still pretty much alchemy (Ali Rahimi's 2017 NIPS Test of Time [1] talk still resonates today) so people rarely spend the effort to effectively refute the bogus claims. As a result, I've opted out of the system and I'm working on trying ambitious ideas I have to try to upend the current paradigm of training on big data, which is truly insane (by age 4 the most erudite of children have probably only been exposed to 45 million words [2] and yet exhibit vastly more understanding and fluency than any language model trained on a similar amount of data).

>In no way can I believe that the corporation doesn’t have a good understanding of exactly how it can manipulate the AI systems it leverages to achieve its goals. See this talk which compares modern AI work to alchemy (i.e. it works, unreliably, and we don't always know why): ▶ this video

This article is a little too glib in my opinion, preferring citations and statements to substance and explanations. For a more cutting and insightful critique, watch Ali Rahimi's short talk at NIPS 2017 (where he was presenting for a paper that won the "Test of time" award, for standing out in value a decade after publication). The standing ovation he received at the end indicate that his comments resonated with a significant fraction of the attendees. ▶ this video Here's a teaser from the talk: "How many of you have devised a deep neural net from scratch, architecture and all, and trained it from the ground up, and when it didn't work, felt bad about yourself, like you did something wrong? This happens to me about every three months, and let me tell you, I don't think it's you [...] I think it's gradient descent's fault. I'll illustrate..." [Addendum] Ben Recht and Ali Rahimi published an adendum to the talk, elaborating on the direction they envision -- link Ali also has a post taking a stab at organizing some puzzling basic observations about deep learning, and motivating that with analogous historical progress in optics -- link ----- PS: The first 11 minutes, on the idea of using random features (the main idea in the research he presented) are also interesting.
