Convergence Analysis of Kernel-based On-policy Approximate Policy Iteration Algorithms for Markov Decision Processes with Continuous, Multidimensional States and Actions
Jun Ma, Warren B. Powell · 2010
Using kernel smoothing techniques, we propose three different online, on-policy approximate policy iteration algorithms which can be applied to infinite horizon problems with continuous and vector-valued states and actions. Using Monte Carlo sampling to estimate the value function around the post-decision state, we reduce the problem to a sequence of deterministic, nonlinear programming problems that allow us to handle continuous, vector-valued states and actions. We provide a formal convergence analysis of the algorithms under a variety of technical assumptions.
