Hi Ronny,
the algorithm i implemented for the Wasserstein barycenter is the fastest i have found in the literature so far.
By ‘Euclidean’ i mean just the Euclidean distance ||P-Q||.
OK, i will check what it takes to allow passing a ManifoldsBase.Manifold to machine leaarning methods of PodSefManifoldML.jl. I will start a thread in the Manifold.jl github.
