A Primer on Flow Matching: Transporting Probability Distributions via Vector Fields

ariG23498 · x · 2026-09-02

A concise explainer of the core idea behind Flow Matching: start from an initial probability distribution and transport it to the target data distribution. The mechanism borrows vector fields from physics — a vector field moves particles from point A to point B, and the vectors are constrained so the endpoints become deterministic. The author tags ML practitioners to sanity-check his understanding.
