Hinge Loss & SVM 2.1 Linearly Separable 我们首先考虑线性可分的场景，即我们可以在空间中找到一个超平面，完美的将正负样本分开。 上图展示了一个数据线性可分的情况下Logistic Regression依然出错的情况。 … Webb20 juni 2014 · For this reason it is usual to consider a proxy to the loss called a surrogate loss function. For computational reasons this is usually convex function $\Psi: \mathbb{R} \to \mathbb{R}_+$. An example of such surrogate loss functions is the hinge loss , $\Psi(t) = \max(1-t, 0)$, which is the loss used by Support Vector Machines (SVMs).
