摘要:

如何有效融合不同时刻的网络结构信息,是影响复杂网络中动态社团检测算法检测性能的关键和难点。基于此,提出了一种基于非负矩阵分解的半监督动态社团检测方法 SDCD-NMF,该方法首先有效提取了历史时刻所包含的稳定结构单元,然后将其作为正则化监督项,指导当前时刻的网络社团检测。在真实网络数据集上的实验表明,所提方法与已有方法相比具备更高的社团划分质量,更有利于探索网络的演变与发展规律。

Abstract:

How to effectively combine the network structures on different time points was the key and difficulty to affect the performance of detection algorithms. Based on this, a semi-supervised dynamic community algorithm SDCD based on non-negative matrix factorization, which effectively extracted the historical stability structure unit firstly, and then use it as a regularization item supervision of nonnegative matrix decomposition, to guide the network community detection on current moment. Experiments on the real network dat sets show that the method has a higher community detection quality compared with existing methods, which can accurately mine the relationship among different time, and explore network evolution and the law of development more adva geously.

Key words: semi-supervised, dynamic, community detection, on-negative matrix factorization
