confusion concerning the kl loss

Open HowToNameMe opened this issue 6 years ago • 5 comments

The output of fc1 can be negative while traning. And in KL loss computing procedure, negative value is not valid. So I wonder how will you explain or modify it.

我想问下，这个kl loss计算的对吗？不应该是他注释掉的那几行才是正确的吗？H(p)可以直接用了l1 loss代替吗

KL loss其实就包含了softmax cross entroy;

请问，作者您在训练前，对人脸裁剪对齐了么？
