Abstract

Diffusion models have revolutionized generative AI. Conceptually, these methods define a transport mechanism from a noise distribution to a data distribution. Recent work has extended this framework to define transports between arbitrary distributions, greatly expanding the potential of these diffusion models. However, existing methods often fail to approximate the optimal transport between these distributions. In this presentation, we will show how current methodologies can be modified to obtain Schrödinger bridges - a regularized entropy variant of dynamically optimal transport.
