Reinforcement Learning: a Comparison of UCB Versus Alternative Adaptive Policies

13 Sep 2019  ·  Wesley Cowan, Michael N. Katehakis, Daniel Pirutinsky ·

In this paper we consider the basic version of Reinforcement Learning (RL) that involves computing optimal data driven (adaptive) policies for Markovian decision process with unknown transition probabilities. We provide a brief survey of the state of the art of the area and we compare the performance of the classic UCB policy of \cc{bkmdp97} with a new policy developed herein which we call MDP-Deterministic Minimum Empirical Divergence (MDP-DMED), and a method based on Posterior sampling (MDP-PS).
