Streaming computation of optimal weak transport barycenters

no code implementations26 Feb 2021 Elsa Cazelles, Felipe Tobar, Joaquin Fontbona

The concept of weak barycenter and our computation approaches are illustrated on synthetic examples, validated on 2D real-world data and compared to the classical Wasserstein barycenters.
