We propose to handle POMDPs in reproducing kernel Hilbert spaces (RKHSs) using recent kernel methods of embedding distributions in an RKHS and kernel Bayes rule (KBR).
We embed Bellman equations to equations over an RKHS on the set of states and define value functions as functions over the RKHS. We then learn a policy as a mapping from elements of the RKHS to actions. We give empirical representations of the Bellman equations and use it for value iteration algorithms with the kernel Bayes rule. In experiments, we demonstrate the kernel value iteration with finite horizons on some benchmarks in POMDPs and show that the policy converged to the policy that the exact model computed. We also propose QMDP approximations with this kernel methods for the setting of initial values and for pruning action edges to make computationally efficient. |
