摘要:

超图是一种有用的组合对象,用于建模实体之间的三元或高阶关系。超图聚类是网络分析中的一项基本任务。在这项研究中,我们开发了两个基于个性化PageRank的超图聚类算法。第一个是局部的,因为它的目标是找到一个紧连通的顶点集,该顶点集具有包含指定顶点的有界体积。第二个是全局的,因为它的目标是找到一个紧密连接的顶点集。对于这两种算法,我们讨论的理论保证的输出顶点集的电导。此外,我们的实验表明,我们的聚类算法优于现有的方法在解决方案的质量和运行时间。据我们所知,我们是第一个实用的算法超图的理论保证的电导的输出集。

英文摘要:

A hypergraph is a useful combinatorial object to model ternary or higher-order relations among entities. Clustering hypergraphs is a fundamental task in network analysis. In this study, we develop two clustering algorithms based on personalized PageRank on hypergraphs. The first one is local in the sense that its goal is to find a tightly connected vertex set with a bounded volume including a specified vertex. The second one is global in the sense that its goal is to find a tightly connected vertex set. For both algorithms, we discuss theoretical guarantees on the conductance of the output vertex set. Also, we experimentally demonstrate that our clustering algorithms outperform existing methods in terms of both the solution quality and running time. To the best of our knowledge, ours are the first practical algorithms for hypergraphs with theoretical guarantees on the conductance of the output set.
