On Geometric Connections of Embedded and Quotient Geometries in Riemannian Fixed-rank Matrix Optimization

no code implementations23 Oct 2021 Yuetian Luo, Xudong Li, Anru R. Zhang

By applying the general procedure to the fixed-rank positive semidefinite (PSD) and general matrix optimization, we establish an exact Riemannian gradient connection under two geometries at every point on the manifold and sandwich inequalities between the spectra of Riemannian Hessians at Riemannian first-order stationary points (FOSPs).
