Recently, multi-view clustering attracts much attention, which aims to take advantage of multi-view information to improve the performance of clustering. However, most recent work mainly focuses on the self-representation-based subspace clustering, which is of high computation complexity. In this paper, we focus on the Markov chain-based spectral clustering method and propose a novel essential tensor learning method to explore the high-order correlations for multi-view representation. We first construct a tensor based on multi-view transition probability matrices of the Markov chain. By incorporating the idea from the robust principle component analysis, tensor singular value decomposition (t-SVD)-based tensor nuclear norm is imposed to preserve the low-rank property of the essential tensor, which can well capture the principle information from multiple views. We also employ the tensor rotation operator for this task to better investigate the relationship among views as well as reduce the computation complexity. The proposed method can be efficiently optimized by the alternating direction method of multipliers (ADMM). Extensive experiments on seven real-world datasets corresponding to five different applications show that our method achieves superior performance over other state-of-the-art methods.
近年来,多视图聚类备受关注,其旨在利用多视图信息来提高聚类性能。然而,最近的大多数工作主要集中在基于自表示的子空间聚类上,这种方法具有很高的计算复杂度。在本文中,我们专注于基于马尔可夫链的谱聚类方法,并提出了一种新颖的本质张量学习方法来探索多视图表示的高阶相关性。我们首先基于马尔可夫链的多视图转移概率矩阵构建一个张量。通过引入鲁棒主成分分析的思想,施加基于张量奇异值分解(t-SVD)的张量核范数来保持本质张量的低秩特性,这可以很好地从多个视图中捕获主要信息。我们还为此任务采用张量旋转算子,以更好地研究视图之间的关系并降低计算复杂度。所提出的方法可以通过交替方向乘子法(ADMM)进行有效优化。在对应于五种不同应用的七个真实世界数据集上进行的大量实验表明,我们的方法比其他现有方法具有更优的性能。
