Additive Models for Symmetric Positive-Definite Matrices and Lie Groups
Biometrika, 2022We propose and investigate an additive regression model for symmetric positive-definite matrix valued responses and multiple scalar predictors. The model exploits the abelian group structure inherited from either of the log-Cholesky and log-Euclidean ...

Pattern Recognition, 2019
Because covariance features with the form of symmetric positive definite matrices lie on Riemannian manifold, classification on Riemannian manifold could possess high performance in many applications.

Subdivision Schemes for Positive Definite Matrices
Foundations of Computational Mathematics, 2012The authors consider subdivision methods generalised from scalar cases to the subdivision of matrices. To this end, they begin with a summary of the basic approaches to subdivision (in the scalar case) by ways of arithmetic and geometric means for instance.
