A Mathematical Introduction to Diffusion Models
Summary
A Mathematical Introduction to Diffusion Models" provides a proof-oriented overview of diffusion models, specifically focusing on sampling dynamics. The notes trace the evolution from classical sampling methods to modern diffusion samplers, incorporating detailed error analysis and techniques for inference-time control. Designed for beginning graduate students, the material assumes a background in probability but no prior knowledge of stochastic differential equations or stochastic numerics. The content is structured into fully proven core definitions and identities, representative estimates demonstrated under simplifying assumptions, and research-level theorems presented with comprehensive proof roadmaps. This resource, published on 2026-07-02, aims to build a foundational understanding of the mathematical underpinnings of diffusion models.
Key takeaway
