New Wasserstein Barycenter Solver Achieves State-of-the-Art Performance

Researchers have developed a new method for computing Wasserstein barycenters, which are used to aggregate probability measures while preserving geometric properties. This novel approach utilizes gradient flows in the space of probability measures, enabling scalable computation through time discretization. The method incorporates mini-batch optimal transport, allows for modular regularization via task-aware functions, and integrates supervised information into the ground-cost. Empirical validation on domain adaptation benchmarks across computer vision, neuroscience, and chemical engineering demonstrates that this new solver establishes a state-of-the-art, with labeled barycenters consistently outperforming unlabeled ones.
