Langevin Diffusion Approximation to Same Marginal Schrödinger Bridge
Medha Agarwal, Zaid Harchaoui, Garrett Mulcahy +1
We introduce a novel approximation to the same marginal Schrödinger bridge using the Langevin diffusion. As , it is known that the barycentric projection…

Diffusion Approximations to Schrödinger Bridges on Manifolds
Garrett Mulcahy, Soumik Pal
We present a collection of explicit diffusion approximations to small temperature Schrödinger bridges on manifolds. Our most precise results are when both marginals are the same a…
