Toy-Diffusion-Models

Introductive implementations of diffusion models on 2D Toy datasets and MNIST.

3 Types of diffusion models are available:

• Vanilla DDPM (https://arxiv.org/abs/2006.11239)
• Vanilla Score-SDE (https://arxiv.org/abs/2011.13456)
  • No Predictor-Corrector (PC) sampling during inference
• Diffusion Model on Discrete Space (https://arxiv.org/abs/2102.05379)
  • Only available for MNIST dataset.
