多层次群落结构的稳定性分析

Analysis of stability of community structure across multiple hierarchical levels

Hui-Jia Li, Xiang-Sun Zhang

摘要:

群落结构的稳定性分析一直是众多科学家关注的重要问题。在这里,我们提出了一个新的框架,揭示隐藏的社区结构的定量分析动力学的波茨模型。具体地说,我们用马尔可夫过程来模拟社区结构检测的Potts过程,这有一个明确的数学解释。关于多元自旋组态的临界拓扑信息也可以从马尔可夫过程的谱意义中推断出来。我们在一些示例网络上测试了我们的框架,发现它根本不存在确定性限制问题。结果表明,我们提出的模型能够有效地揭示不同尺度下的层次结构。

英文摘要:

The analysis of stability of community structure is an important problem for scientists from many fields. Here, we propose a new framework to reveal hidden properties of community structure by quantitatively analyzing the dynamics of Potts model. Specifically we model the Potts procedure of community structure detection by a Markov process, which has a clear mathematical explanation. Critical topological information regarding to multivariate spin configuration could also be inferred from the spectral significance of the Markov process. We test our framework on some example networks and find it doesn't have resolute limitation problem at all. Results have shown the model we proposed is able to uncover hierarchical structure in different scales effectively and efficiently.
