16.10.2018 · This notebook breaks down how binary_cross_entropy_with_logits function (corresponding to BCEWithLogitsLoss used for multi-class classification) is implemented in pytorch, and how it is related to sigmoid and binary_cross_entropy.. Link to notebook:

Sep 14, 2017 · It is not F.binary_cross_entropy_with_logits because this function assumes multi label classification: F.sigmoid + F.binary_cross_entropy = F.binary_cross_entropy_with_logits It is not torch.nn.functional.nll_loss either because this function takes log-probabilities (after log_softmax()) not logits.

13.09.2017 · is there an equivalent PyTorch loss function for TensorFlow's softmax_cross_entropy_with_logits?. torch.nn.functional.cross_entropy. This takes logits as inputs (performing log_softmax internally). Here "logits" are just some values that are not probabilities (i.e. not necessarily in the interval [0,1]).. But, logits are also the values that will be …
