Tutorial on Diffusion Models for Imaging and Vision

Overview

Paper Summary

This tutorial provides a comprehensive overview of diffusion models, tracing their development from variational autoencoders (VAEs) to denoising diffusion probabilistic models (DDPMs) and score-matching Langevin dynamics (SMLD). It also explores the connection between diffusion models and stochastic differential equations (SDEs), providing insights into their underlying principles and behavior.

Explain Like I'm Five

Imagine slowly adding noise to an image until it's pure static, then learning to reverse this process step-by-step. Diffusion models generate images by reversing this noise process, gradually revealing a clear picture from random static.
