Yuandong Tian - Finding Good Representation for Search and Exploration in RL @ UCL DARK

Invited talk by Yuandong Tian (Facebook AI Research) on April 12, 2021 at UCL DARK.
Abstract: How to learn good latent representations is an important topic in the modern era of machine learning. For reinforcement learning, using a good representation makes the decision-making process much more efficient. In this talk, I will cover our work that constructs task-specific latent action space for search-based optimization of black-box functions, finds a representation for policy change that enables joint policy search in imperfect information collaborative games and how different representations affect RL exploration.
