WebFeb 8, 2024 · For multi-class classification you would usually just use nn.CrossEntropyLoss, and I don’t think you’ll end up with the same result, as you are calling torch.sigmoid on each prediction. For multi-label classification, you might use nn.BCELoss with hot-encoded targets and won’t need a for loop. WebJan 7, 2024 · Binary Cross Entropy (nn.BCELoss) This loss metric creates a criterion that measures the BCE between the target and the output. Also with binary cross-entropy loss function, we use the Sigmoid activation function which works as a squashing function and hence limits the output to a range between 0 and 1.
