WebMargin ranking loss. Creates a criterion that measures the loss given inputs x 1, x 2, two 1D mini-batch Tensors , and a label 1D mini-batch tensor y (containing 1 or -1). If y = 1 then it assumed the first input should be ranked higher (have a larger value) than the second input, and vice-versa for y = − 1. WebJan 7, 2024 · Margin Ranking Loss (nn.MarginRankingLoss) Margin Ranking Loss computes the criterion to predict the distances between inputs. This loss function is very different from others, like MSE or Cross-Entropy loss function. This function can calculate the loss provided there are inputs X1, X2, as well as a label tensor, y containing 1 or -1. WebKGEs.
