Phase loss weights about apnet2 HOT 3 OPEN

Hello softrimewu, you're absolutely right. Regarding the issue of the MRD coefficient, we refer to the configuration of Vocos. As for the problem of discriminator overfitting, it is mentioned in this article. Although using such a discriminator directly can improve the quality of the waveform to a certain extent, if you want to further address the overfitting issue, you can refer to the approach mentioned in PhaseAug. Due to time constraints, we haven't had a chance to try it ourselves.

This is my loss curve. We have the same problem during training. However, during the experiment, it was found that if the weight based on the phase loss function is too small, the sound quality will deteriorate. Our guess is that phase needs to be given a higher weight than amplitude. At the same time, you can also see from the image I gave that Instantaneous_Phase_Loss has almost not dropped, and this problem also needs to be solved.

Have you checked your MRD loss? It is a bit confusing for me to use 0.1 weight for generator mrd loss while use 1.0 weight for mrd loss. In my observation the prediction of MRD becomes really close to 0 on generated samples while 1 on real samples which seems reasonable for this loss weight but unexpected.
