A new class of algorithms called Representation Policy Iteration (RPI) are presented that automatically learn both basis functions and approximately optimal policies. Illustrative experiments compare the performance of RPI with that of LSPI using two handcoded basis functions (RBF and polynomial state encodings).

Policyn ska verka styrande och gäller 3. Policy Iteration and Approximate Policy Iteration Policy iteration (Howard, 1960) is a method of discovering the optimal policy for any given MDP. Policy iteration is an iterative procedure in the space of deterministic policies; it discovers the optimal policy by generating a sequence of monotonically improving policies. Representation i hemmet ska undvikas och får endast undantagsvis medges av prefekt och då ska särskild motivering bifogas verifikatet.

In this book, we also focus on policy iteration, value and policy neural network representations, parallel and distributed computation, and lookahead simplification. Thus while there are significant differences, the principal design ideas that form the core of this monograph are shared by the AlphaZero architecture, except that we develop these ideas in a broader and less application-specific framework.

It is based on the method of state space decomposition implemented by introducing a binary tree. Combining the RPI algorithm with the state space decomposition method, the HRPI algorithm is proposed. Aiming at this problem, this paper presents a novel kernel-based representation policy iteration (KRPI) method for reinforcement learning in optimal path tracking of mobile robots. In the proposed method, the kernel trick is employed to map the original state space into a high-dimensional feature space and the Laplacian operator in the feature space is obtained by minimizing an objective function of optimal embedding. This paper introduces a Fuzzy C-means method as the subsampling method for Representation Policy Iteration (RPI) in Reinforcement Learning. RPI is a new class of algorithm that automatically learns both basis functions and approximately optimal policy.
