Researchers have developed an accelerated stochastic variance-reduced algorithm designed to efficiently compute entropic Wasserstein barycenters. This new method improves upon existing deterministic accelerated gradient approaches by offering a square-root factor improvement in dependence on the barycenter support size, while maintaining accelerated performance relative to target accuracy. Experimental results on various datasets, including images and digit averaging, demonstrate the algorithm's effectiveness and lower arithmetic costs compared to other first-order methods. AI
