时变网络中的时间稳定社区

Temporal Stable Community in Time-Varying Networks

Wenjing Wang, Xiang Li

摘要:

识别复杂网络的社区结构提供了对网络拓扑结构和网络涌现的集体行为之间的相互依赖性的洞察,而在时变网络中检测这样的不变社区更具挑战性。本文定义了时变网络中的稳定社区,并提出了动态模块度的概念来评价时变网络中的稳定社区结构。此外,利用功能脑网络中时间稳定社区的波动特征,我们成功地区分了ADHD(注意缺陷多动障碍)患者和健康对照。

英文摘要:

Identifying community structure of a complex network provides insight to the interdependence between the network topology and emergent collective behaviors of networks, while detecting such invariant communities in a time-varying network is more challenging. In this paper, we define the temporal stable community and newly propose the concept of dynamic modularity to evaluate the stable community structures in time-varying networks, which is robust against small changes as verified by several empirical time-varying network datasets. Besides, using the volatility features of temporal stable communities in functional brain networks, we successfully differentiate the ADHD (Attention Deficit Hyperactivity Disorder) patients and healthy controls efficiently.
