Sparse sample self-representation for subspace clustering
摘要
Abstract
Existing subspace clustering methods do not combine sample self⁃representation well with affinity matrix sparsity, for example, by removing disturbances from noise, outliers, etc., when constructing the affinity matrix. This paper proposes a novel subspace clustering method called sparse sample self⁃representation for subspace cluste⁃ring. This method fully considers the correlation between the samples, and also takes advantage of L1⁃norm and L2,1⁃norm terms to “penalize” the affinity matrix;that is, it conducts sparse sample self⁃representation for all test samples, to guarantee every sample can be expressed by any other samples with strong similarity and make it more robust. The experimental results of the Hopkins155 dataset and some facial image datasets show that the proposed method outperforms the LSR, SSC, and LRR methods in terms of the subspace clustering error.关键词
