Sinkhorn Barycenters with Free Support via Frank-Wolfe Algorithm

–Neural Information Processing Systems
We present a novel algorithm to estimate the barycenter of arbitrary probability distributions with respect to the Sinkhorn divergence. Based on a Frank-Wolfe optimization strategy, our approach proceeds by populating the support of the barycenter incrementally, without requiring any pre-allocation.
