Keyword Arguments: WebJun 2, 2024 · I want to create a custom loss function in Torch which is a modification of ClassNLLCriterion. Concretely, ClassNLLCriterion loss is: loss (x, class) = -x [class] I want to modify this to be: loss (x, class) = -x [class]*K. where K is a function of the network input, NOT the network weights or network output. Thus K can be treated as a constant.
