Geometries on the cone of positive-definite matrices derived from the power potential and their relation to the power means

Nadia Chouaieb, Bruno Iannazzo, Maher Moakher

We study a Riemannian metric on the cone of symmetric positive-definite matrices obtained from the Hessian of the power potential function . We give explicit expre…

Approximate Joint Diagonalization and Geometric Mean of Symmetric Positive Definite Matrices

Marco Congedo, Bijan Afsari, Alexandre Barachant +1

We explore the connection between two problems that have arisen independently in the signal processing and related fields: the estimation of the geometric mean of a set of symmetri…
