Matters Of Scale:
-
“Scaling Laws for Neural Language Models”, et al 2020 (NN LMs appear to be nowhere near saturation nor training infeasibility as larger models show predictable gains and are both more compute-efficient & data-efficient (!)—onwards to GPT-3?)
-
“Big Transfer (BiT): Large Scale Learning of General Visual Representations for Transfer”, et al 2019 ( blog; JFT-300M showing larger=better: large benchmark gains, transfer everywhere, much more robust representations, more plausible errors, etc)
-
“DD-PPO: Learning Near-Perfect PointGoal Navigators from 2.5 Billion Frames”, et al 2019 ( blog; “et al 2019 benchmarked classical (mapping + planning) and learning-based methods…and showed that classical methods outperform learning-based. However, they trained for ‘only’ 5 million steps…et al 2019 then scaled this training to 75 million steps and found that this trend reverses…Fig. 1 shows an agent does not saturate before 1 billion steps, suggesting that previous studies were incomplete by 1–2 orders of magnitude.”)
-
“Meena: Towards a Human-like Open-Domain Chatbot”, et al 2020 ( blog; 2.6b parameters trained on 341GB text, although et al 2020 suggests they’d’ve done better to go much bigger & trained much less than 164 epoches; likelihood loss near identical with human-rated performance? Likelihood loss seems ultimately a flawed metric, but maybe we’re still far from hitting its limits…)

Technology:
-
“Cats, Once YouTube Stars, Are Now an ‘Emerging Audience’: They’re addicted to channels like Little Kitty & Family, Handsome Nature, and Videos for Your Cat—provided their owners switch on the iPad first” (After reading this, I gave videos-for-cats another try with my cat, since he gets stir-crazy in winter. I full-screened it, in landscape mode; he continued resolutely ignoring the screen as always, until I left my earphones out and he heard the birds chirping—he went nuts, convinced a bird had gotten into the apartment, until he finally noticed the screen, and I could see the instant the lightbulb went on and he was hooked. He’ll watch videos like Paul Dinning’s “8 Hour Bird Bonanza” for as many hours as I’ll leave it on, hunting behind the monitor for the birds, and makes a nuisance of himself sitting in front of it, waiting for the birds to come back—which he is doing as I try to write this! These are truly superstimuli: cats would never see these many birds this close up so unsuspecting in the wild.)
