WebJan 4, 2024 · You do not have to define the operation in the lambda layer itself. It can be defined in a function and passed on to the lambda layer. Here is a function that takes data and squares it: def active1 (x): return x**2. Now, this function can be simply passed into the lambda layer like this: WebSoftmax def forward (self, x): x = self. linear1 (x) x = self. activation (x) ... This is beneficial because many activation functions (discussed below) have their strongest gradients near 0, but sometimes suffer from vanishing or exploding gradients for inputs that drive them far away from zero. Keeping the data centered around the area of ...
