WebMar 16, 2024 · Now we are going to see loss functions in PyTorch that measures the loss given an input tensor x and a label tensor y (containing 1 or -1). When could it be used? The hinge embedding loss function is used for classification problems to determine if the inputs are similar or dissimilar. WebPyTorch offers all the usual loss functions for classification and regression tasks — binary and multi-class cross-entropy, mean squared and mean absolute errors, smooth L1 loss, neg log-likelihood loss, and even Kullback-Leibler divergence. A detailed discussion of these can be found in this article. The Optimizer phones with front fingerprint scanner
