Understanding the Denoising Diffusion Probabilistic Model, the Socratic Way | by Wei Yi | Feb, 2023
A deep dive into the motivation behind the denoising diffusion model and detailed derivations for the loss functionPhoto by Chaozzy Lin on UnsplashThe Denoising Diffusion Probabilistic Models by Jonathan Ho et. al. is a great paper. But I had difficulty understanding it. My colleagues told me they were also left confused after reading it. So I decided to dive into the model and worked out all the derivations. In this article, I will focus on the two main obstacles to understand the paper:why the denoising diffusion model…
