Limited resolution and multiresolution methods in complex network community detection

J. M. Kumpula, J. Saramaki, K. Kaski, J. Kertesz

摘要:

在现实世界的网络中检测社区结构是一个具有挑战性的问题。最近,它已被证明,基于优化模块化措施或相应的能量的方法的分辨率是有限的,社区的大小低于一些阈值仍然没有解决。解决这个问题的一种可能性是通过使用调优参数来改变阈值,并在可变分辨率下研究社区结构。在这里,我们分析了两种不同的方法的分辨率极限和多分辨率行为:由Reichard和Bornholdt提出的q状态Potts方法,以及最近由Arenas,Fernandez和Gomez提出的多分辨率方法。这些方法进行了分析研究,并应用到三个测试网络,使用模拟退火。

英文摘要:

Detecting community structure in real-world networks is a challenging problem. Recently, it has been shown that the resolution of methods based on optimizing a modularity measure or a corresponding energy is limited; communities with sizes below some threshold remain unresolved. One possibility to go around this problem is to vary the threshold by using a tuning parameter, and investigate the community structure at variable resolutions. Here, we analyze the resolution limit and multiresolution behavior for two different methods: a q-state Potts method proposed by Reichard and Bornholdt, and a recent multiresolution method by Arenas, Fernandez, and Gomez. These methods are studied analytically, and applied to three test networks using simulated annealing.
