在L2正则化之后的weights和features基础之上,引入了 使得角度空间中类间的决策边界最大化,如下图所示: 上图是ArcFace的几何解释:(a)蓝色和绿色点代表了两个不同类别的向量特征,比如蓝色代表一些猫的图片向量特征,绿色代表一些狗的图片向量特征。ArcFace可以直接进一步增加两种类别间隔。(2)右边更加直观地解释了角度...
weights = F.normalize(self.weights, p=2, dim=-1) # 计算余弦相似度 cosine_sim = F.linear(features, weights) # 添加ArcFace的角度余弦距离调整 theta = torch.acos(torch.clamp(cosine_sim, -1.0 + 1e-7, 1.0 - 1e-7)) marginal_cosine = torch.cos(theta + self.margin) ...
SphereFace assumes that the linear transformation matrix in the last fully con- nected layer can be used as a representation of the class centres in the angular space and therefore penalises the an- gles between deep features and their corresponding weights in a mul...
