Criterion outputs batch_y
Webcriterion = AbsCriterion () Creates a criterion that measures the mean absolute value between n elements in the input x and output y: loss (x,y) = 1/n \sum x_i-y_i . If x and y are d -dimensional Tensors with a total of n elements, the sum operation still operates over all the elements, and divides by n. The division by n can be avoided if one ...
