text: Title: Want to understand the loss
  Body: Hi, Thank you for the awesome work.
  
  I have read the issues about blurred outputs like: [1](https://github.com/junyanz/pytorch-CycleGAN-and-pix2pix/issues/1388#issuecomment-1062187740) and [2](https://github.com/junyanz/pytorch-CycleGAN-and-pix2pix/issues/656#issuecomment-510935442).
  
  May i have your explanations why increase the weight of identity loss and cycle-consistenty loss can improve the problem?
  Thank you!
