Margin based loss
WebMargin losses are an important category of losses. If you have two inputs, this loss function says you want one input to be larger than the other one by at least a margin. In this case y y is a binary variable \in { -1, 1} ∈ −1,1. Imagine the two inputs are scores of two categories.
