different samplers in the temporal co-denoising

[tszFung-gz]

Hello [, First of all, thanks for the great work. I've been exploring the denoising process and found the results quite interesting. I have a question regarding the use of different samplers in the temporal co-denoising process. In my experiments, I observed that the choice of sampler can significantly affect the results. For instance, when using the DDPM sampler, there appear to be notable differences compared to using other samplers. Could you please shed some light on why this is the case? Is there any underlying mechanism or theoretical explanation that could help me better understand the reason behind these observed effects? Any guidance or pointer towards relevant literature would be greatly appreciated. Thank you in advance for your help!
