Diffusion Seminar
2026 Summer seminar on The Principles of Diffusion Models by Lai, Song, Kim, Mitsufuji, and Ermon.
We read one chapter per week, starting July 6.
Week 1 : Variational Perspective: From VAEs to DDPMs
Open SessionThis chapter develops the variational view of diffusion models, beginning with the variational autoencoder (VAE) and building up to the denoising diffusion probabilistic model (DDPM).
Week 2 : Score-Based Perspective: From EBMs to NCSN
Open SessionThis chapter traces the score-based view of generative modeling, moving from energy-based models (EBMs) to score-based generative models.
Week 3 : Diffusion Models Today: Score SDE Framework
Open SessionThis chapter presents the Score SDE framework that underpins modern diffusion models, casting the forward and reverse processes as stochastic differential equations with a matching probability-flow ODE.
Week 4 : Flow-Based Perspective: From NFs to Flow Matching
Open SessionThis chapter introduces the flow-based view, connecting normalizing flows and neural ODEs to the flow matching framework.
Week 5 : A Unified and Systematic Lens on Diffusion Models
Open SessionThis chapter brings the variational, score-based, and flow-based perspectives together, showing how they share a common backbone and are largely equivalent.
Week 6 : Guidance and Controllable Generation
Open SessionThis chapter covers how to steer diffusion models toward desired outputs.
Week 7 : Sophisticated Solvers for Fast Sampling
Open SessionThis chapter studies advanced numerical solvers that accelerate sampling from diffusion models.
Week 8 : Distillation-Based Methods & Learning Fast Generators from Scratch
Open SessionThis session covers two complementary routes toward fast diffusion-based generators.
