Hi @alexzhou907 , It is a really nice work!
I've been going through the code in Line91 of karras_diffusion.py and Line93 of karras_diffusion.py of the same file, and I've got a question regarding the parameter 't' in the functions vp_logsnr and vp_logs. It seems to consistently have a value of 1. Could you kindly clarify why this value is chosen for 't'?
Hi! These are to get the SNR for T, which is 1 for all my experiments. These constants are needed to rescale the input, output, etc. just as in EDM. Please refer to the paper for details.
