WebFeb 15, 2024 · Negative log likelihood loss ( nn.NLLLoss) The previous two loss functions involved binary classification. In other words, they can be used for a classifier that works with two possible targets only - a class 0 and a class 1. However, many classification problems involve more than two classes. Webcriterion = L1HingeEmbeddingCriterion (margin) Creates a criterion that measures the loss given an input x = {x1,x2}, a table of two tensors, and a label y (1 or -1): This is used for measuring whether two inputs are similar or dissimilar, using the L1 distance, and is typically used for learning nonlinear embeddings or semi-supervised learning.
