  • Optimal Transport Barycenter via Nonconvex-Concave Minimax Optimization

    Optimal Transport Barycenter via Nonconvex-Concave Minimax Optimization arXiv:2501.14635v1 Announce Type: new Abstract: The optimal transport barycenter (a.k.a. Wasserstein barycenter) is a fundamental notion of averaging that extends from the Euclidean space to the Wasserstein space of probability distributions. Computation of the unregularized barycenter for discretized probability distributions on point clouds is a challenging task when…
