New bounds enhance statistical inference for Reinforcement Learning

Researchers have developed new high-dimensional concentration inequalities and Berry-Esseen bounds for martingales induced by Markov chains. These findings are applied to analyze Temporal Difference (TD) learning with linear function approximations, a key method in Reinforcement Learning (RL). The study provides a strong consistency guarantee for TD learning and establishes an $O(T^{-rac{1}{4}}\log T)$ distributional convergence rate for the TD estimator. AI
