Webb13 dec. 2024 · The hinge loss is a loss function used for “maximum-margin” classification, most notably for support vector machine (SVM).It’s equivalent to minimize the loss function L ( y, f) = [ 1 − y f] +. With f ( x) = h ( x) T β + β 0, the optimization problem is loss + penalty: min β 0, β ∑ n = 1 ∞ [ 1 − y i f ( x i)] + + λ 2 β 2 2. Exponential loss Webb0.

It penalizes the model when there is a difference in the sign … Webb16 apr. 2024 · A last piece of terminology is the threshold at zero and \(max(0,-)\) is often called Hinge Loss. Sometimes, we may use Squared Hinge Loss instead in practice, with the form of \(max(0,-)^2\), in order to penalize the violated margins more strongly because of the squared sign. In some datasets, square hinge loss can work better.
