      Gary Marcus Retweeted Yann LeCun

      . @Ylecun are you arguing that your team has a robust solution to the problem of getting deep nets to understand the causal consequences of events as they unfold over time, or just pointing me to a toy model? Have you tried it on the examples in this thread?https://twitter.com/ylecun/status/1188902027495006208 …

      Wrong. See this: https://arxiv.org/abs/1612.03969  Look at Table 2: Row 7 (counting) and 14 (time reasoning) both get 0 error rates (this is on bAbI tasks). When you are fighting a rear-guard battle, it's best to know when you adversary overtook your rear 3 years ago.

      This all-or-nothing approach to progress is pretty silly. I'm sure it's a toy model, and I'm sure you'll find flaws with it, but that doesn't mean it's not progress.

      Hey, I'm all for taking steps, but Dr @ylecun told me the problem was solved, period, and that's completely ridiculous.

      Not only did @ylecun claim the problem of buiding models of causal consequences from discourse was solved, he said it's been solved for 3 years! Spoiler: It hasn't been.

      Did he really? My read: You claimed no robust event representations in GPT-2, he claimed (albeit rudely) that older work exhibited this property.

      right, which makes his reply a non sequitur. I said GPT-2 doesn''t develop robust representations of *how events unfold over time*; he pointed to a different architecture w memory etc. bait-and-switch and overstated.

      "models like GPT-2" is a very subjective thing. He probably thinks models /w external memory are in the same family (as would I), whereas you probably count them as a "hybrid model".
