Immanuel M. Bomze, Francesco Rinaldi, Damiano Zeffiro

摘要:

聚类检测在数据分析中起着基础性的作用。在本文中,我们专注于使用s-亏损团模型基于网络的聚类检测,并提出了一个非线性最优化的方法,有效地处理这些模型在实践中。特别是,我们引入了一个等价的连续配方分析下的问题,我们分析了一些定制的变体的弗兰克-沃尔夫算法,使我们能够快速找到最大的s-缺陷集团。这些算法工具的良好的实用性,这是密切相关的支持识别性能,使他们在实际应用中非常有吸引力。所报告的数值结果清楚地表明所提出的方法的有效性。

英文摘要:

Cluster detection plays a fundamental role in the analysis of data. In this paper, we focus on the use of s-defective clique models for network-based cluster detection and propose a nonlinear optimization approach that efficiently handles those models in practice. In particular, we introduce an equivalent continuous formulation for the problem under analysis, and we analyze some tailored variants of the Frank-Wolfe algorithm that enable us to quickly find maximal s-defective cliques. The good practical behavior of those algorithmic tools, which is closely connected to their support identification properties, makes them very appealing in practical applications. The reported numerical results clearly show the effectiveness of the proposed approach.
