深度度量学习(Deep Metric Learning, DML) 在很多场景中都发挥着重要的作用,一个经典的应用就是人脸识别,Google 的FaceNet模型使用Triplet-Loss刷新了当时人脸识别的记录,近两年基于Softmax改进的Angular-Softmax, Additive Margin Softmax等在人脸识别成功应用的损失函数,都引入了度量学习的思想。 基于深度学习的度量学习...

作者先是回顾了目前存在的一些loss, 从上图可以看到,ranked list loss也就是本文提出的方法,在训练中充分利用了输入样本信息。 本文的想法是把正例样本与负例样本以mm隔开,类内样本允许存在α−mα−m的分布差异,如下图所示: 成对约束: 其基于成对损失,上图可以表示为:Lm(xi,xj;f)=(1−yij)[α−...
