      @GaryMarcus In your paper "DL: A Critical Appraisal" you mention a test you did for generalization during 1998. Its is still a good generalization test? Which is in your opinion the best generalization test for a AI?

      There are (and should be) many different ways to assess generalization, but you might start with @LakeBrenden’s updates to my late 90’s work. And look at @dileeplearning’s work on how DQN fails in tiny changes to Atari games.

      Our blogs and papers highlight important aspects of generalization in vision, dynamics, and concept learning. https://www.vicarious.com/blog/  @vicariousai

      Do you consider at Vicarious that your tech & team have achieved generalization?

      Of course not. We have good generalization in some limited settings. We think we have some of the right ingredients, but a lot more work remains.

      Yup, I'm a big fan of @dileeplearning and @vicariousai 🙂 Just to clarify from my previous posts: I wasn't saying that DeepMind doesn't hype their work; they absolutely do. I was just questioning your criticism that they don't have a successful deep RL *commercial product*.

      They don’t have a successful commercial product that they have sold outside Alphabet. That’s just a fact AFAIK. But I very much read you as saying they weren’t making especially grand claims, which I think they are.

      Why should they sell outside of Alphabet? The 'only made $100 million' line in your article was similarly baffling -- what's your point of comparison?

      if they had a real product, why not? deepmind does have an applied/product division, and has had one maybe since inception. on the latter surely the notion of comparing revenue with costs didn’t originate me.

          Internal products are still products, $100M is noteworthy given the basic research focus. The notion of using revenue/costs to assess scientific merit is rather unique to you. What lab is doing better by this metric? Has it historically been a precursor to larger innovation?

          @Zergylord please reread; i absolutely did not judge the scientific value of DRL on $revenue. multiple paragraphs pointing out other limits, before economic analysis.
