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.
WebJul 29, 2024 · Loss functions induced by the (left) tanh and (right) ReLU activation functions. Each loss is more sensitive to the regions affecting the output prediction. For instance, ReLU loss is zero as long as both the prediction (â) and the target (a) are negative. This is because the ReLU function applied to any negative number equals zero. WebAug 25, 2024 · This function will generate examples from a simple regression problem with a given number of input variables, statistical noise, and other properties. We will use this …
WebTanh Function (Hyperbolic Tangent) Mathematically it can be represented as: Advantages of using this activation function are: The output of the tanh activation function is Zero centered; hence we can easily map the output values as strongly negative, neutral, or strongly positive. 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 …
