关于线性矩阵方程秩约束解的注记

A note on rank constrained solutions to linear matrix equations

Shravan Mohan

AI总结:

本文提出一种启发式方法求解线性矩阵方程的秩约束解,通过最小化非凸二次函数(称作低秩函数)实现,虽无严格证明,但通过模拟验证其有效性。

摘要:

本文提出了一种启发式方法用于求解线性矩阵方程的秩约束解。该方法基于最小化一个非凸二次函数(称为低秩函数)。尽管该方法缺乏严格的证明和全面的分析,例如在概率保证收敛到解方面,但该方法具有直观性,并在模拟中表现出良好的性能。为此,提供了许多数值例子以验证该想法。

英文摘要:

This preliminary note presents a heuristic for determining rank constrained solutions to linear matrix equations (LME). The method proposed here is based on minimizing a non-convex quadratic functional, which will hence-forth be termed as the \textit{Low-Rank-Functional} (LRF). Although this method lacks a formal proof/comprehensive analysis, for example in terms of a probabilistic guarantee for converging to a solution, the proposed idea is intuitive and has been seen to perform well in simulations. To that end, many numerical examples are provided to corroborate the idea.
