چکیده
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.

Scaling-Rotation Distance and Interpolation of Symmetric Positive-Definite Matrices
We introduce a new geometric framework for the set of symmetric positive-definite (SPD) matrices, aimed at characterizing deformations of SPD matrices by individual scaling of eigenvalues and rotation of eigenvectors of the SPD matrices. To characterize the deformation, the eigenvalue-eigenvector decomposition is used to find alternative representations of SPD matrices and to form a Riemannian ...
متن کاملProximal Point Algorithm with Schur Decomposition on the Cone of Symmetric Semidefinite Positive Matrices∗
In this work, we propose a proximal algorithm for unconstrained optimization on the cone of symmetric semidefinite positive matrices. It appears to be the first in the proximal class on the set of methods that convert a Symmetric Definite Positive Optimization in Nonlinear Optimization. It replaces the main iteration of the conceptual proximal point algorithm by a sequence of nonlinear programm...
متن کاملChapter 17 Approximating a Convex Body by An Ellipsoid
In the following, we cover some material from linear algebra. Proofs of those facts can be found in any text on linear algebra, for example [Leo98]. For a matrix A, let A T denote the transposed matrix. We remind the reader that for two matrices A and B, we have (AB) T = B T A T. Furthermore, for any three matrices A, B and C, we have (AB)C = A(BC). A matrix A ∈ IR n×n is symmetric if A T = A. ...
متن کاملApproximating the Distributions of Singular Quadratic Expressions and their Ratios
Noncentral indefinite quadratic expressions in possibly non- singular normal vectors are represented in terms of the difference of two positive definite quadratic forms and an independently distributed linear combination of standard normal random variables. This result also ap- plies to quadratic forms in singular normal vectors for which no general representation is currently available. The ...
متن کاملFast $(1+\epsilon)$-approximation of the L\"owner extremal matrices of high-dimensional symmetric matrices
Matrix data sets are common nowadays like in biomedical imaging where the Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) modality produces data sets of 3D symmetric positive definite matrices anchored at voxel positions capturing the anisotropic diffusion properties of water molecules in biological tissues. The space of symmetric matrices can be partially ordered using the Löwner ordering...
