摘要翻译：
低秩建模在信号处理和机器学习中发挥着关键作用，应用范围从协同过滤、视频监控、医学成像到降维和自适应滤波。许多现代高维数据及其相互作用可以近似地被建模为位于一个低维子空间或流形中，可能具有额外的结构，对其进行适当的开发可以显著降低传感、计算和存储成本。近年来，在理解如何利用计算效率高的程序以可证明的方式开发低阶结构方面取得了许多进展，包括凸和非凸方法。一方面，核范数最小化等凸松弛常导致估计低秩矩阵的统计最优过程，其中一阶方法被开发以解决计算挑战；另一方面，有新的证据表明，适当设计的非凸过程，如投影梯度下降，往往在许多问题中以更低的计算代价提供全局最优解。这篇调查文章将提供一个统一的概述这些最近的进展，从不完全测量的低秩矩阵估计。注意这些算法性能的严格表征，以及低秩矩阵具有需要新的算法设计和理论分析的额外结构性质的问题。

英文摘要：
  Low-rank modeling plays a pivotal role in signal processing and machine learning, with applications ranging from collaborative filtering, video surveillance, medical imaging, to dimensionality reduction and adaptive filtering. Many modern high-dimensional data and interactions thereof can be modeled as lying approximately in a low-dimensional subspace or manifold, possibly with additional structures, and its proper exploitations lead to significant reduction of costs in sensing, computation and storage. In recent years, there is a plethora of progress in understanding how to exploit low-rank structures using computationally efficient procedures in a provable manner, including both convex and nonconvex approaches. On one side, convex relaxations such as nuclear norm minimization often lead to statistically optimal procedures for estimating low-rank matrices, where first-order methods are developed to address the computational challenges; on the other side, there is emerging evidence that properly designed nonconvex procedures, such as projected gradient descent, often provide globally optimal solutions with a much lower computational cost in many problems. This survey article will provide a unified overview of these recent advances on low-rank matrix estimation from incomplete measurements. Attention is paid to rigorous characterization of the performance of these algorithms, and to problems where the low-rank matrix have additional structural properties that require new algorithmic designs and theoretical analysis.
