WebJan 13, 2024 · nn.CrossEntropyLoss. and the last layer is just a nn.Linear () layer, At last ,when I want to get the softmax probability, I can use like this : out_put=model (intput) probability= torch.nn.functional.softmax (out_put,dim=1) Now the probability is same as what you get in tensorflow or keras softmax. 2 Likes. WebThe softmax activation function takes in a vector of raw outputs of the neural network and returns a vector of probability scores. The equation of the softmax function is given as follows: Softmax Function Equation (Image by the author) Here, z is the vector of raw outputs from the neural network. The value of e ≈ 2.718.
