社交网络中小集合扩张与模块聚类的关系

On a Connection Between Small Set Expansions and Modularity Clustering in Social Networks

Bhaskar DasGupta, Devendra Desai

摘要:

在本文中,我们探讨了两个看似不同的问题之间的连接从两个不同的领域:在独特的游戏猜想研究的小集扩展问题,和一个流行的社区发现方法的社交网络被称为模块化聚类方法。我们表明,一个次指数时间算法的小集合扩展问题导致一个次指数时间常数因子近似的模块化聚类问题的一些硬输入实例。

英文摘要:

In this paper we explore a connection between two seemingly different problems from two different domains: the small-set expansion problem studied in unique games conjecture, and a popular community finding approach for social networks known as the modularity clustering approach. We show that a sub-exponential time algorithm for the small-set expansion problem leads to a sub-exponential time constant factor approximation for some hard input instances of the modularity clustering problem.
