Building a Binary Classification Model in PyTorch

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. http://www.iotword.com/4800.html small games pc download
