    Batch size is one of the most important and most debated questions in large-scale training. We still rely on heuristics: linear scaling (Goyal et al) critical batch size (McClandlish et al.) hyperparameter transfer (Yang et al.) We show that under a fixed token budget, there

    I have postdoc and PhD positions on optimization, RL, and deep learning theory in my group lions.epfl.ch at EPFL. Send me an email if you are interested in meeting with me in person at ICML. Please share to potentially interested parties.

    Good news: Two of my postdocs got faculty offers (Technion & Linkoping). Better news (please retweet): My group has postdoc positions in the general area of Machine Learning with emphasis on optimization, deep learning, and reinforcement learning. Other areas are also possible.

    Dear @icmlconf AC's, In the "view author feedback" menu, you can ask further questions to authors to give them another chance to clarify additional issues that may arise during the discussion period. As an AC myself, I cannot emphasize how impactful this is. Use it! Do it now!

    A huge effort finally paid off: Robust reinforcement learning via adversarial training with Langevin dynamics will be presented @NeurIPSConf arxiv.org/abs/2002.06063. It also has some elementary results on why adversarial training is hard for first order methods.
