Orthogonal Trace-Sum Maximization: Tightness of the Semidefinite Relaxation and Guarantee of Locally Optimal Solutions
Joong-Ho Won, Teng Zhang, Hua Zhou
This paper studies an optimization problem on the sum of traces of matrix quadratic forms in semi-orthogonal matrices, which can be considered as a generalization of the synchr…
Tightness of the semidefinite relaxation for orthogonal trace-sum maximization
Teng Zhang
This paper studies an optimization problem on the sum of traces of matrix quadratic forms on orthogonal matrices, which can be considered as a generalization of the synchroniza…
Phase retrieval using alternating minimization in a batch setting
Teng Zhang
This paper considers the problem of phase retrieval, where the goal is to recover a signal from the observations , . While many algorithms…
A Majorization-Minimization Algorithm for Computing the Karcher Mean of Positive Definite Matrices
Teng Zhang
An algorithm for computing the Karcher mean of positive definite matrices is proposed, based on the majorization-minimization (MM) principle. The proposed MM algorithm is param…
