This paper proposes a novel method for computing Schrödinger Bridges, which are diffusion processes used to steer an initial distribution to a final one while minimizing a cost functional. The authors introduce an analytic parametrization of feasible policies for steering Gaussian Mixture Models (GMMs) and show that the optimal policy can be approximated as the solution of a low-dimensional linear program. This approach generalizes naturally to more complex dynamical systems, such as controllable Linear Time-Varying systems. The authors demonstrate the potential of this method in image-to-image translation tasks and benchmark its performance on an Entropic Optimal Transport problem, showing that it outperforms state-of-the-art methods.

This paper is about finding a way to move from one picture to another by using a special kind of math called Schrödinger Bridges. Normally, these bridges are hard to compute and require lots of training data. But the authors have come up with a new method that can solve this problem more efficiently. They show how their approach works well for certain types of images and even outperforms other methods in some cases.
