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 … Web如下图，分别是Cosface[8]和CircleSoftmax[4]的训练测试过程。 CosFace训练测试过程. CircleSoftmax训练测试过程. Loss设计. Loss设计上使用了Focal Loss[6]和CrossEntropy Loss联合训练的方案，避免了Focal Loss需要调整超参和过度放大困难样本权重的问题。 how do you get from bergen to alesund
