WebOct 18, 2024 · If your data input to tanh has a magnitude of 10 or more, tanh produces an output of 1. That means it treats 10, 50, 100, 1000 the same. We don't want that. This would explain the input vector with the weights turns out to be too large, which makes tanh (x)=1tanh (x)=1 and 1−o2=01−o2=0, so I can't learn. 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.
