Web1 day ago · The loss is then expressed as: (3) T r i p l e t E A, E P, E N = max 0, f E A, E P-f E A, E N + α where α represents the margin parameter. A first limitation of the traditional formulation is that, for a random selection of the image triplet, it is possible that f(E A,E P)≥f(E P,E N) even if the condition in Eq. (3) is satisfied as f(E A,E ...

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.
