Explaining Flow Matching: using vector fields to transform probability distributions

RisingSayak · x · 2026-09-02

The post explains the concept of Flow Matching in simple terms: starting from an initial probability distribution, it leverages the concept of vector fields from Physics to transport particles (data points) from point A to point B. By constraining these vectors appropriately, the method transforms the initial distribution into the target data distribution, providing an intuitive way to understand distribution transformation in generative models.
