Approximating Sets of Symmetric and Positive-Definite Matrices by Geodesics
Keyword(s):
We formulate a generalized version of the classical linear regression problem on Riemannian manifolds and derive the counterpart to the normal equations for the manifold of symmetric and positive definite matrices, equipped with the only metric that is invariant under the natural action of the general linear group.
