TL;DR提出了一种名为Fast Median Subspace (FMS)的快速非凸算法来进行强健的子空间恢复，具有较低的计算复杂性和全局收敛特性，能够有效地处理高维空间中的异常值问题。
Abstract
This paper presents a fast algorithm for robustsubspace recovery. The datasets considered include points drawn around a low-dimensional subspace of a higher dimensional ambient space, and a possibly large portio
