摘要:

随着技术的进步,可以在多个视图中观察实体。包含不同类型特征的多个视图可用于聚类。虽然多视图聚类已经在很多应用中得到了成功的应用,但以往的方法通常假设不同视图之间的实例映射是完整的。在许多现实世界的应用程序中,信息可以从多个来源收集,而每个来源可以包含多个视图,这对于学习来说更有凝聚力。同一源下的视图通常是完全映射的,但它们可能非常异构。此外,不同来源之间的映射通常是不完整的,部分观察,这使得它更难以整合所有的意见,跨不同的来源。在本文中,我们提出了MMC(多源多视图聚类),这是一个框架的基础上集体谱聚类与差异惩罚跨源,以应对这些挑战。MMC与其他现有方法相比具有若干优点。首先,MMC可以处理源之间的不完全映射。其次,它考虑了源之间的分歧,同时将同一源中的视图视为一个内聚集。第三,MMC还尝试推断源之间的实例相似性,以提高聚类性能。在真实数据上进行的大量实验证明了该方法的有效性。

英文摘要:

With the advance of technology, entities can be observed in multiple views. Multiple views containing different types of features can be used for clustering. Although multi-view clustering has been successfully applied in many applications, the previous methods usually assume the complete instance mapping between different views. In many real-world applications, information can be gathered from multiple sources, while each source can contain multiple views, which are more cohesive for learning. The views under the same source are usually fully mapped, but they can be very heterogeneous. Moreover, the mappings between different sources are usually incomplete and partially observed, which makes it more difficult to integrate all the views across different sources. In this paper, we propose MMC (Multi-source Multi-view Clustering), which is a framework based on collective spectral clustering with a discrepancy penalty across sources, to tackle these challenges. MMC has several advantages compared with other existing methods. First, MMC can deal with incomplete mapping between sources. Second, it considers the disagreements between sources while treating views in the same source as a cohesive set. Third, MMC also tries to infer the instance similarities across sources to enhance the clustering performance. Extensive experiments conducted on real-world data demonstrate the effectiveness of the proposed approach.
