Web1 Answer Sorted by: 2 Why don't you convert your discrete predictions (e.g., [1, 0, 4, 10]) with "soft" predictions, i.e. probability of each label (e.g., output becomes a 4x (num labels) probability vectors). Once you have "soft" predictions, you can compute the cross entropy loss between the predicted output probabilities and the desired targets. WebJan 20, 2024 · A vector in PyTorch is a 1D tensor. To compute pairwise distance between two vectors, we can use the PairwiseDistance () function. It uses p-norm to compute the pairwise distance. PairwiseDistance is basically a class provided by the torch.nn module. The size of both the vectors must be same.
