results fluctuate #15

When I train your model on other datasets (such as SID), the validation results fluctuate a lot. Is this normal? Do you have any suggestions for parameter settings? This is my training log, looking forward to your reply. train.log

I observed that the validation results in your log become relatively stable after 265k (i.e., Tune-PSNR is around 23.7, and Tune-SSIM is around 0.675). This may be because the diffusion model produces stochastic results. For example, when you change a random number seed, PSNR and SSIM will also bring great changes.

Got it, thank you for your prompt reply and your excellent work.
