摘要:

子空间聚类是指找到一个多子空间表示,最适合从一个高维空间的点的集合的任务。本文介绍了一种受稀疏子空间聚类(SSC)[In IEEE Conference on计算机视觉and模式识别,CVPR(2009)2790-2797]启发的噪声数据聚类算法,并发展了一些新的理论来证明其正确性。特别是,该理论使用几何泛函分析的思想来证明该算法可以在对它们的方向和每个子空间的样本数量的最小要求下准确地恢复底层子空间。合成以及真实的数据实验补充了我们的理论研究,说明了我们的方法,并证明其有效性。

英文摘要:

Subspace clustering refers to the task of finding a multi-subspace representation that best fits a collection of points taken from a high-dimensional space. This paper introduces an algorithm inspired by sparse subspace clustering (SSC) [In IEEE Conference on Computer Vision and Pattern Recognition, CVPR (2009) 2790-2797] to cluster noisy data, and develops some novel theory demonstrating its correctness. In particular, the theory uses ideas from geometric functional analysis to show that the algorithm can accurately recover the underlying subspaces under minimal requirements on their orientation, and on the number of samples per subspace. Synthetic as well as real data experiments complement our theoretical study, illustrating our approach and demonstrating its effectiveness.
