Hello, I am a graduate student in China and have the privilege of reading your BBDM paper published in CVPR2023 at arXiv. The derivation of some formulas in the paper is not very clear. Would it be convenient for you to provide a contact email for your consultation? thank you.

Thank you for your attention. Some of the deduction details can be found in the appendix. https://arxiv.org/abs/2205.07680 If you have any other questions, you can specify the parts for me. my email: xuekt98@gmail.com

Hi @zhangXJ147 and @xuekt98 ,

I have a question (#29) regarding the reverse process as for my understanding of this equation in line 198 in the code it should be equivalent to Eq 12 in the paper, right?

However, when I implemented Eq 12 directly and compared both of them they didn't give the same result which means your implementation (line 198) is different from the Eq 12 in the paper. More specifically, the difference is only in the X0 coefficient.

Thanks in advance!
