Global Convergence of Triangularized Orthogonalization-free Method
Weiguo Gao, Yingzhou Li, Bichen Lu
This paper proves the global convergence of a triangularized orthogonalization-free method (TriOFM). TriOFM, in general, applies a triangularization idea to the gradient of an obje…

Triangularized Orthogonalization-free Method for Solving Extreme Eigenvalue Problems
Weiguo Gao, Yingzhou Li, Bichen Lu
A novel orthogonalization-free method together with two specific algorithms are proposed to solve extreme eigenvalue problems. On top of gradient-based algorithms, the proposed alg…
