复杂网络中基于信令的社区发现

Community Detecting By Signaling on Complex Networks

Yanqing Hu, Menghui Li, Peng Zhang, Ying Fan, Zengru Di

摘要:

基于复杂网络中的信令过程,提出了一种社区结构识别方法.对于具有$n$节点的网络,假设每个节点是可以发送、接收和记录信号的系统。每个节点作为初始信号源一次,通过激励其邻居节点来激励整个网络,然后赋予源节点一个$n$ d向量,记录信令过程的效果。这样,网络上节点的拓扑关系就转化为$n$ d欧氏空间中向量的几何结构。然后利用$F$ -统计量确定最佳的群体划分,最后利用模糊$C$ -均值聚类方法(FCM)给出最终的群落结构。该方法不需要任何额外的参数就能检测出加权网络和未加权网络中的社团结构。它已被应用于adhoc网络和一些实际的网络,包括扎卡里空手道俱乐部网络和足球队网络。与其他方法的结果进行了比较,证据表明,基于信令过程的算法是有效的。

英文摘要:

Based on signaling process on complex networks, a method for identification community structure is proposed. For a network with $n$ nodes, every node is assumed to be a system which can send, receive, and record signals. Each node is taken as the initial signal source once to inspire the whole network by exciting its neighbors and then the source node is endowed a $n$d vector which recording the effects of signaling process. So by this process, the topological relationship of nodes on networks could be transferred into the geometrical structure of vectors in $n$d Euclidian space. Then the best partition of groups is determined by $F$-statistic and the final community structure is given by Fuzzy $C$-means clustering method (FCM). This method can detect community structure both in unweighted and weighted networks without any extra parameters. It has been applied to ad hoc networks and some real networks including Zachary Karate Club network and football team network. The results are compared with that of other approaches and the evidence indicates that the algorithm based on signaling process is effective.
