Denoising Diffusion Probabilistic Model (DDPM)

This repository implements a basic version of the Denoising Diffusion Probabilistic Model (DDPM) based on the tutorial in Understanding Diffusion Models: A Unified Perspective. The DDPM was originally introduced by Ho et al. in Denoising Diffusion Probabilistic Models.

For a tutorial of the algorithm and the mathematics of the model, refer to tutorial.ipynb.
