摘要:

多视图聚类是一个重要而具有挑战性的任务,由于难以整合来自多个表示的信息。现有的多视图聚类方法大多是利用数据点所在空间的异构信息进行聚类。由于不可避免的噪音或视图之间的不一致性,这种常见做法可能导致大量信息丢失。由于不同的观点承认相同的集群结构,自然空间应该是所有分区。正交现有的技术,在本文中,我们提出了利用多视图信息融合分区。具体来说,我们通过不同的旋转矩阵对齐每个分区以形成共识聚类指示矩阵。此外,为每个视图分配权重,以考虑视图的聚类能力差异。最后,在统一的框架中共同学习基本分区、权重和共识聚类。我们证明了我们的方法在几个真实的数据集上的有效性,在其他国家的最先进的多视图聚类方法中发现了显着的改善。

英文摘要:

Multi-view clustering is an important yet challenging task due to the difficulty of integrating the information from multiple representations. Most existing multi-view clustering methods explore the heterogeneous information in the space where the data points lie. Such common practice may cause significant information loss because of unavoidable noise or inconsistency among views. Since different views admit the same cluster structure, the natural space should be all partitions. Orthogonal to existing techniques, in this paper, we propose to leverage the multi-view information by fusing partitions. Specifically, we align each partition to form a consensus cluster indicator matrix through a distinct rotation matrix. Moreover, a weight is assigned for each view to account for the clustering capacity differences of views. Finally, the basic partitions, weights, and consensus clustering are jointly learned in a unified framework. We demonstrate the effectiveness of our approach on several real datasets, where significant improvement is found over other state-of-the-art multi-view clustering methods.
