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 WebSoftcase Iphone 14 Pro Max 14 Plus Silicone Liquid Square Edge Case - SILICONE LILAC, 14 PRO MAX di Tokopedia ∙ Promo Pengguna Baru ∙ Cicilan 0% ∙ Kurir Instan.
