摘要:

本文介绍了一种新的技术来跟踪结构的时间演化图。该方法是基于一个参数自由的方法,用于三维的源顶点,目标顶点和时间的共同聚类。所有这些特征同时被分割,以建立时间段和顶点的集群,其边缘分布是相似的,并在时间段上以相同的方式演变。这种方法的主要新颖之处在于,直接从顶点之间的边缘分布的演变推断出时间段,从而不需要用户进行先验离散化。在合成数据集上进行的实验说明了该技术的良好性能,对现实生活中的数据集的研究显示了所提出的探索性数据分析方法的潜力。

英文摘要:

This paper introduces a novel technique to track structures in time evolving graphs. The method is based on a parameter free approach for three-dimensional co-clustering of the source vertices, the target vertices and the time. All these features are simultaneously segmented in order to build time segments and clusters of vertices whose edge distributions are similar and evolve in the same way over the time segments. The main novelty of this approach lies in that the time segments are directly inferred from the evolution of the edge distribution between the vertices, thus not requiring the user to make an a priori discretization. Experiments conducted on a synthetic dataset illustrate the good behaviour of the technique, and a study of a real-life dataset shows the potential of the proposed approach for exploratory data analysis.
