WebNov 25, 2024 · 2 Answers Sorted by: 7 If you know that for each example you only have 1 of 10 possible classes, you should be using CrossEntropyLoss, to which you pass your networks predictions, of shape [batch, n_classes], and labels of shape [batch] (each element of labels is an integer between 0 and n_classes-1 ). WebAug 4, 2024 · So, my understanding is that I should sum the scores of the activations for the positive labels and negative labels. If there are no positive labels the positive-sum term would be 0, giving a bad loss (1-0+ (sum of activations of negative class)) to the model (I guess) as it should be! The simple example at the end seems to be numerically correct. port forwarding globeWebJan 7, 2024 · Margin Ranking Loss (nn.MarginRankingLoss) Margin Ranking Loss computes the criterion to predict the distances between inputs.
