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. WebIt should only be compatible with the values you want to get out (and thus also with the loss function you are using). Both the tanh and sigmoid (or logistic) functions can be used for output which should be bounded, and …
WebThe add_loss() API. Loss functions applied to the output of a model aren't the only way to create losses. When writing the call method of a custom layer or a subclassed model, you may want to compute scalar quantities that you want to minimize during training (e.g. regularization losses). You can use the add_loss() layer method to keep track of such loss … WebMar 20, 2024 · The loss function explodes at random points in time, sometimes sooner, sometimes later. I read this thread about possible problems, but at this point after trying multiple things I am not sure what to do to prevent the loss function from skyrocketing at random. Any advice is appreciated.
WebThe left plot shows that the rational approximant and the actual function are almost visually indistinguishable, while the right plot depicts the function $\tanh\,z-R(z)$. One other possibility you can use in conjunction with rational function approximation is the use of argument reduction; in particular, the identity
