Webtorch.nn.functional.binary_cross_entropy(input, target, weight=None, size_average=None, reduce=None, reduction='mean') [source] Function that measures the Binary Cross Entropy between the target and input probabilities. See BCELoss for details. … WebCross-entropy is the go-to loss function for classification tasks, either balanced or imbalanced. It is the first choice when no preference is built from domain knowledge yet. This would need to be weighted I suppose? How does that work in practice? Yes. Weight of class c is the size of largest class divided by the size of class c. imfs perth
