Multi-Resolution Noise

[Guzaiwang]

Hi, first, thanks much for sharing the training codes.

I found a few differences between your reproduction and the original paper. In the original paper, multi-resolution noise is adapted for a significant performance improvement. However, your coding uses torc.randn_like() to produce noise.

Is my understanding correct or not? Actually, I am new to the diffusion model. If yes, is there any next plan to implement the multi-resolution noise in your codes?

I'm looking forward to hearing back from you.

Best regards.
