About the time to end training

[ZhenyuLiu-SYSU]

Hello!
Thank you so much for doing such a good job.
I would like to know that when do I end the training while training for the best results?
And is there any basis for judgment?

Thank you！

Hello Zhenyu,
Many thanks for your kind words!
For best results, you may record the FID score every epoch. But better FID score does not always suggests better translation. Hence I would suggest referring to FID, KID, LPIPS for a comprehensive evaluation.

Usually I would suggest training for 1M iterations, for instance , to train on a dataset contraining 5000 images, 200 epochs should be fine.

Thanks for your reply!
And I try to train the code on the winter2summer dataset and found that DCL's FID >SimDCL's FID.
This doesn't seem consistent with the fact that DCL mentioned in your paper works better than SimDCL
Do you think this is normal？

Thanks！

Oh I guess that's OK. Datasets may have some bias, I won't be surprised if the difference is not very significant (let's say, 100 for SimDCL but 130+ for DCL).
