24.11.2019 · The loss you're looking at is designed for situations where each example can belong to multiple classes (say a person can be classified as both female and old). I think it's this "multi" that confuses you - it stands for the multiple possible classifications per example , not just multiple potential labels in the whole "universe".
It corresponds to Kendall's τ, which measures the correlation between two rankings. Margin The margin loss returns the number of positions between the worst.
MultiLabelMarginLoss class torch.nn.MultiLabelMarginLoss(size_average=None, reduce=None, reduction='mean') [source] Creates a criterion that optimizes a multi-class multi-classification hinge loss (margin-based loss) between input x x (a 2D mini-batch Tensor ) and output y y (which is a 2D Tensor of target class indices).
