Mixture of Geodesic Factor Analyzers on Riemannian Homogeneous Spaces

arXiv:2608.06971v1 Announce Type: new Abstract: This paper introduces Mixtures of Geodesic Factor Analyzers (MGFA) on Riemannian homogeneous spaces. MGFA uses a geodesic factor model within each mixture component, providing greater expressiveness than mixtures of Riemannian radial distributions and enabling clustering
