Web27 Feb 2024 · 2 Smooth Hinge Losses The support vector machine (SVM) is a famous algorithm for binary classification and has now also been applied to many other machine learning problems such as the AUC learning, multi-task learning, multi-class classification and imbalanced classification problems [ 27, 18, 2, 14] . Web7 Jul 2016 · Hinge loss does not always have a unique solution because it's not strictly convex. However one important property of hinge loss is, data points far away from the decision boundary contribute nothing to the loss, the solution will be the same with those points removed. The remaining points are called support vectors in the context of SVM.
