WebFeb 19, 2015 · Jordan , Pieter Abbeel ·. We describe an iterative procedure for optimizing policies, with guaranteed monotonic improvement. By making several approximations to the theoretically-justified procedure, we develop a practical algorithm, called Trust Region Policy Optimization (TRPO). This algorithm is similar to natural policy gradient methods ... Webpolicy gradient, its performance level and sample efficiency remain limited. Secondly, it inherits the intrinsic high vari-ance of PG methods, and the combination with hindsight …

Trust Region Policy Optimization (TRPO) Explained
WebNov 29, 2024 · I will briefly discuss the main points of policy gradient methods, natural policy gradients, and Trust Region Policy Optimization (TRPO), which together form the stepping stones towards PPO. Vanilla policy gradient. A good understanding of policy gradient methods is necessary to comprehend this article. WebApr 25, 2024 · 2 Trust Region Policy Optimization (TRPO) Setup. As a policy gradient method, TRPO aims at directly maximizing equation \(\ref{diff}\), but this cannot be done because the trajectory distribution is under the new policy \(\pi_{\theta'}\) while the sample trajectories that we have can onlu come from the previous policy \(q\). WebAug 10, 2024 · We present an overview of the theory behind three popular and related algorithms for gradient based policy optimization: natural policy gradient descent, trust region policy optimization (TRPO) and proximal policy optimization (PPO).
