Flow matching can be understood as a continuation of continuous normalizing flows, which transform a base density such as a normal distribution into a target density.

“Flow matching actually comes from uh so there are two ways of t think about flow matching. One is you can think about them as like the the continuation of continuous normalising flows. The idea of a continuous or like any normalising flow is you have a base density, so a normal distribution, and you frame your problem now as trying to figure out a transformation which goes from that base density to your target density.”
