Learning over von Mises-Fisher Distributions via a Wasserstein-like Geometry arXiv:2504.14164v1 Announce Type: new Abstract: We introduce a novel, geometry-aware distance metric for the family of von Mises-Fisher (vMF) distributions, which are fundamental models for directional data on the unit hypersphere. Although the vMF distribution is widely employed in a variety of probabilistic learning tasks involving…
