Understanding Denoising Diffusion Probabilistic Models

Although there are many blogs online introducing DDPM with detailed mathematical derivations, I still feel confused and unable to connect the dots between different content, not knowing why things are done in a certain way. I think this is probably because theory serves as an explanation for experimental results, and understanding from a coding perspective may be easier. Therefore, this article attempts to start from the most basic denoising methods,...
