Sparse is Enough in Scaling Transformers

no code implementations NeurIPS 2021 Sebastian Jaszczur, Aakanksha Chowdhery, Afroz Mohiuddin, Łukasz Kaiser, Wojciech Gajewski, Henryk Michalewski, Jonni Kanerva

We study sparse variants for all layers in the Transformer and propose Scaling Transformers, a family of next generation Transformer models that use sparse layers to scale efficiently and perform unbatched decoding much faster than the standard Transformer as we scale up the model size.

Q-Value Weighted Regression: Reinforcement Learning with Limited Data

1 code implementation12 Feb 2021 Piotr Kozakowski, Łukasz Kaiser, Henryk Michalewski, Afroz Mohiuddin, Katarzyna Kańska

QWR is an extension of Advantage Weighted Regression (AWR), an off-policy actor-critic algorithm that performs very well on continuous control tasks, also in the offline setting, but has low sample efficiency and struggles with high-dimensional observation spaces.

Forecasting Deep Learning Dynamics with Applications to Hyperparameter Tuning

no code implementations25 Sep 2019 Piotr Kozakowski, Łukasz Kaiser, Afroz Mohiuddin

Concretely, we introduce a forecasting model that, given a hyperparameter schedule (e. g., learning rate, weight decay) and a history of training observations (such as loss and accuracy), predicts how the training will continue.
