WebJun 29, 2024 · Hello, My network has Softmax activation plus a Cross-Entropy loss, which some refer to Categorical Cross-Entropy loss. See: In binary classification, do I need one-hot encoding to work in a network like this in PyTorch? I am using Integer Encoding. Just as matter of fact, here are some outputs WITHOUT Softmax activation (batch = 4): outputs: … WebJan 18, 2024 · # Softmax applies the exponential function to each element, and normalizes # by dividing by the sum of all these exponentials # -> squashes the output to be between 0 and 1 = probability # sum of all probabilities is 1: def softmax(x): return np.exp(x) / np.sum(np.exp(x), axis=0) x = np.array([2.0, 1.0, 0.1]) outputs = softmax(x)

How to correctly use Cross Entropy Loss vs Softmax for classification?

WebApr 14, 2024 · I want to use tanh as activations in both hidden layers, but in the end, I should use softmax.
