摘要:

复杂系统在日常生活中无处不在,抽象地表示为网络。分析和理解这些系统需要社区发现工具等。由于不可能存在单一的最佳社区发现算法,因此期望跨各种各样的问题设置的鲁棒性。在这项工作中,我们提出了Synwalk,一个基于随机行走的社区发现方法。Synwalk建立在坚实的理论基础上,通过从一类候选随机游走中合成给定网络引起的随机游走来检测社区。我们彻底验证了我们的方法的有效性合成和经验网络,分别,并比较Synwalk的性能与性能的信息地图和Walktrap。我们的研究结果表明,Synwalk在具有不同混合参数和度分布的网络上具有鲁棒性。我们在具有高混合参数的网络上优于Infomap,在具有许多小社区和低平均度的网络上优于Infomap和Walktrap。我们的工作有可能激发进一步发展的社区发现通过合成的随机游动,我们为未来的研究提供了具体的思路。

英文摘要:

Complex systems, abstractly represented as networks, are ubiquitous in everyday life. Analyzing and understanding these systems requires, among others, tools for community detection. As no single best community detection algorithm can exist, robustness across a wide variety of problem settings is desirable. In this work, we present Synwalk, a random walk-based community detection method. Synwalk builds upon a solid theoretical basis and detects communities by synthesizing the random walk induced by the given network from a class of candidate random walks. We thoroughly validate the effectiveness of our approach on synthetic and empirical networks, respectively, and compare Synwalk's performance with the performance of Infomap and Walktrap. Our results indicate that Synwalk performs robustly on networks with varying mixing parameters and degree distributions. We outperform Infomap on networks with high mixing parameter, and Infomap and Walktrap on networks with many small communities and low average degree. Our work has a potential to inspire further development of community detection via synthesis of random walks and we provide concrete ideas for future research.
