文中提出了一种基于对的相似性优化方法，基于对的优化的方法目的都是最大化类内相似性 s_p 同时最小化类间相似性 s_n 。文中发现大多数的损失函数，包括triplet loss 和softmax激活函数加交叉熵损失函数，都是使 s_n 和 s_p 嵌入到一个相似性对，并且去减小 (s_n-s_p) 。这样的优化方式是不够灵活的，因为其对每一个单 … See more Circle loss的思想还是根据相似得分来对其反向传播的权重进行动态调整，这点是和focal loss[7]是一样的，focal loss是根据分类的概率动态调整反向传播的权重的。文中提到的Multi-Similarity … See more WebSep 19, 2024 · 假设AM-softmax能够完全优化，那么参考L-softmax中的图，取原始softmax中余弦为 cosθ1 ,AM-softmax中为 cosθ1′ = cosθ1 −m 即 cosθ1 = cosθ1′ +m ，我们知道余弦值越大，角度越小，因此AM-softmax与L-softmax一样，将类内的距离缩小了。 Circle-loss 虽然上述2个损失能够将类内距离进一步缩小，类间距离进一步增大，但是实 …
