Highway env ppo

WebMar 25, 2024 · PPO The Proximal Policy Optimization algorithm combines ideas from A2C (having multiple workers) and TRPO (it uses a trust region to improve the actor). The main idea is that after an update, the new policy should be not too far from the old policy. For that, ppo uses clipping to avoid too large update. Note Webhighway-env is a Python library typically used in Artificial Intelligence, Reinforcement Learning applications. highway-env has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can install using 'pip install highway-env' or download it from GitHub, PyPI.

WebPPO policy loss vs. value function loss. I have been training PPO from SB3 lately on a custom environment. I am not having good results yet, and while looking at the tensorboard graphs, I observed that the loss graph looks exactly like the value function loss. It turned out that the policy loss is way smaller than the value function loss.

WebMay 3, 2024 · As an on-policy algorithm, PPO solves the problem of sample efficiency by utilizing surrogate objectives to avoid the new policy changing too far from the old policy. The surrogate objective is the key feature of PPO since it both regularizes the policy update and enables the reuse of training data.
