Max-margin可以近似为\arg \max _{\theta} \mathcal{M}_{i, i^{\prime}} \simeq \arg \max _{\theta} \mathcal{L}_{m r g}=\frac{\sum_{i}^{N} D_{i}^{I n t r a}}{\sum_{i}^{N} D_{i}^{\text {Inter }}} 这里我的理解是,分子的类内距离尽可能小,分母的类间距离尽可...
Hinge Loss是一种目标函数(或者说损失函数)的名称,有的时候又叫做max-margin objective。其最著名的应用是作为SVM的目标函数。 其二分类情况下,公式如下: l(y)=max(0,1−t⋅y) 其中,y是预测值(-1到1之间),t为目标值(±1)。 其含义为,y的值在-1到1之间就可以了,并不鼓励|y|>1,即并不鼓励分类...

在这篇文章中,作者们提出了一种新的基于SVM的对比学习框架,取名为 max-margin contrastive learning。对于常规的 soft-margin SVM,其目标函数为: minw,b,ξ12‖w‖2+C∑xξx s.t. yx(w⊤x+b)⩾1−ξx, ∀x∈X+∪X− 其Lagrangian dual 具有如下形式: min0⩽α⩽C,α⊤y=012α⊤...
