Web1 mar 2024 · Using this estimator, we develop a new Proximal Hybrid Stochastic Policy Gradient Algorithm (ProxHSPGA) to solve a composite policy optimization problem that allows us to handle constraints or regularizers on the policy parameters. We first propose a single-looped algorithm then introduce a more practical restarting variant. We prove that … Web12 lug 2024 · Policy Gradient (SVRPG)17 is a random variance reduction algorithm of the policy gradient used to solve the Markov Decision Process (MDP). SVRPG uses the importance sampling weight to retain the unbiased gra-dient estimation, which can ensure convergence under the standard assumption of MDP. But the above algo-
