New theory bridges Newton-Raphson method and Regularized Policy Iteration

Researchers have established a formal equivalence between the Newton-Raphson method and Regularized Policy Iteration (RPI) when applied to regularized Markov Decision Processes (RMDPs). This connection, particularly evident when the regularizer is Shannon entropy, allows for a unified theoretical analysis of RPI and the development of accelerated algorithms. The study demonstrates that RPI exhibits local quadratic convergence, and proposes a new algorithm achieving third-order local convergence, supported by numerical experiments. AI

    Bridging the Gap between Newton-Raphson Method and Regularized Policy Iteration

    arXiv:2310.07211v2 Announce Type: replace Abstract: Regularization is a cornerstone of modern reinforcement learning. Regularized policy iteration (RPI) provides a fundamental scheme for solving regularized Markov decision processes (RMDPs), and the widely used soft actor-critic …
