内容简介:
Given two candidate functions, can we identify which one is the true value function of a large Markov decision process (MDP), given a "benign" dataset? Trivial as it might seem, a version of the question was open for 20+ years in reinforcement learning (RL), and the core difficulties are intimately related to the training instability of modern deep RL. In this talk, I will argue that by rethinking fundamental questions like this, RL theory can provide unique perspectives and solutions to practically relevant problems that are critical to the deployment of RL in real-world scenarios.
