用核范数惩罚法恢复张量的凸性

Convex recovery of tensors using nuclear norm penalization

Stephane Chretien, Tianwen Wei

摘要:

实矩阵奇异谱的凸函数的次微分在矩阵分析、最优化和自动控制理论中有着广泛的研究。张量空间上的凸分析和优化由于其在信号处理、统计和工程中的潜在应用而引起人们的广泛兴趣。本文的目的是将Tropp的结果推广到张量设置,给出了一个基于线性随机测量的低秩张量恢复问题的应用。

英文摘要:

The subdifferential of convex functions of the singular spectrum of real matrices has been widely studied in matrix analysis, optimization and automatic control theory. Convex analysis and optimization over spaces of tensors is now gaining much interest due to its potential applications to signal processing, statistics and engineering. The goal of this paper is to present an applications to the problem of low rank tensor recovery based on linear random measurement by extending the results of Tropp to the tensors setting.
