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.

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. design shed plans
