Diffusion Family: DDPM
In this blog we will try to understand the member of diffusion family, DDPM. Given the common structure shared by variational autoencoders (VAEs) and diffusion models, we will first discuss some important content in VAE, and then introduce the DDPM. The blog will try to be self-contained and mathematically clear, but some prior knowledge of VAEs and generative models is assumed. References: VAE on Wikipedia Lil’Log What are Diffusion Models?...
