Loss Function & Its Inputs For Binary Classification PyTorch
stackoverflow.com › questions › 53628622
Dec 05, 2018 · For binary classification (say class 0 & class 1), the network should have only 1 output unit. Its output will be 1 (for class 1 present or class 0 absent) and 0 (for class 1 absent or class 0 present). For loss calculation, you should first pass it through sigmoid and then through BinaryCrossEntropy (BCE).

Oct 03, 2018 · Hi everyone, I am trying to implement a model for binary classification problem. Up to now, I was using softmax function (at the output layer) together with torch.NLLLoss function to calculate the loss. However, now I want to use the sigmoid function (instead of softmax) at the output layer. If I do that, should I also change the loss function or may I still use torch.NLLLoss function?
