WebJul 9, 2024 · Margin Ranking Loss (MRL) has been one of the earlier loss functions which is widely used for training TransE. However, the scores of positive triples are not necessarily enforced to be sufficiently small to fulfill the translation from head to tail by using relation vector (original assumption of TransE). 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.
