About reconstructing from noise?

Hi @tanelp. Wondering if there's any material I can refer to for understanding how the reconstruction from noise works. TIA

Hi @Sreerag-ibtl , I'm also learning this amazing code. Not sure if you got answers. But basically, I found this code strictly follows the equations here https://arxiv.org/abs/2208.11970
Specifically,
reconstruct_x0 -> Eq. (69) on page 11
q_posterior and get_variance -> Eq. (84) on page 12

Other methods should be straightforward.

Really appreciate @tanelp 's work cause this code is so clean and easy to understand.
