A generalized power iteration method for solving quadratic problem on the Stiefel manifold
收藏 引用
Science China(Information Sciences) 2017年 第11期60卷 146-155页
作者: Feiping NIE Rui ZHANG Xuelong LI School of Computer Science and Center for OPTical IMagery Analysis and Learning(OPTIMAL) Northwestern Polytechnical University Center for OPTical IMagery Analysis and Learning (OPTIMAL) State Key Laboratory of Transient Optics and Photonics Xi'an Institute of Optics and Precision MechanicsChinese Academy of Sciences
In this paper, we first propose a novel generalized power iteration(GPI) method to solve the quadratic problem on the Stiefel manifold(QPSM) as minWTW =ITr(WTAW-2WTB) along with the theoretical analysis. Accordingly, ... 详细信息

Frontiers of Mathematics in China 2016年 第6期11卷 1379-1418页
作者: Mu-Fa CHEN School of Mathematical Sciences Beijing Normal University Laboratory of Mathematics and Complex Systems (Beijing Normal University) Ministry of Education Beijing 100875 China
This paper introduces some efficient initials for a well-known algorithm (an inverse iteration) for computing the maximal eigenpair of a class of real matrices. The initials not only avoid the collapse of the algori... 详细信息
