What is the role of entropy loss? about cgdm

[duzhekai]

Hi, the entropy loss serves as a class balance regularization item which is inherited from MCD original paper and relative methods (please refer to the supplementary material of MCD). In addition, we mentioned this in the implementation details.

I am aware of the loss used on MCD paper, it is given as follows.

https://github.com/mil-tokyo/MCD_DA/blob/af10217c5c5451dcd8bc3e975a7d067c285cc029/visda_classification/res_train_main.py#L145

which seems to be different to the loss you used .

CGDM/utils.py

Line 419 in 2d8fee0

entropy = input_ * torch.log(input_)

Can you explain the difference? Also, you additionally used an entropy minimization loss which is not used in MCD and also never mentioned in your paper.
