Simple classification accuracy is OK but in many scenarios you want a so-called confusion matrix that gives details of the number of correct and wrong predictions for each of the two target classes. You also want precision, recall, and… WebFunction that measures Binary Cross Entropy between target and input logits. See BCEWithLogitsLoss for details. Parameters: input ( Tensor) – Tensor of arbitrary shape as unnormalized scores (often referred to as logits). target ( Tensor) – Tensor of the same shape as input with values between 0 and 1 lidia bastianich corn and zucchini minestra
