Riemannian block SPD coupling manifold and its application to optimal transport
Andi Han, Bamdev Mishra, Pratik Jawanpuria +1
In this work, we study the optimal transport (OT) problem between symmetric positive definite (SPD) matrix-valued measures. We formulate the above as a generalized optimal transpor…

Learning with symmetric positive definite matrices via generalized Bures-Wasserstein geometry
Andi Han, Bamdev Mishra, Pratik Jawanpuria +1
Learning with symmetric positive definite (SPD) matrices has many applications in machine learning. Consequently, understanding the Riemannian geometry of SPD matrices has attracte…
