Geometry and barycenters in large $\CAT(κ)$ spaces

Yassine Boukhateb, Victor-Emmanuel Brunel, Austin J. Stromme

We study the geometry and resulting properties of Fréchet functions and barycenters in metric spaces with curvature bounded above by a positive constant in the sense of Alexandrov.…

Finite-sample bounds for regularized optimal transport

Alberto González-Sanz, Marcel Nutz, Austin J. Stromme

We study the sample complexity of regularized optimal transport for general convex regularizations including the Kullback--Leibler divergence and penalties. Our main results…
