Definition of flow matching
-
: a method for training a continuous generative model by teaching it the vector field that moves samples along chosen probability paths from a simple distribution, such as noise, toward the data distribution

Origin & history
Yaron Lipman and collaborators introduced Flow Matching for generative modeling in a 2022 paper. They described a simulation-free training objective for continuous normalizing flows that regresses vector fields along conditional probability paths, including paths related to diffusion models.
