I will add definitions, proofs, worked examples, and questions as I work through the subject. Study log September 13, 2026 — Notebook created. Study entries will follow. Notes To be added as my study progresses. Questions I will collect questions and points to revisit here. References Reading materials will be listed here as I use them. https://HaitongLan.github.io/p/optimal-transport/ Sun, 13 Sep 2026 00:00:00 +0800 https://HaitongLan.github.io/p/optimal-transport/ This notebook will record my study of optimal transport during graduate school.
