动态接触网络中时间节点轮廓的聚类

Clustering of temporal nodes profiles in dynamic networks of contacts

Mehdi Djellabi, Bertrand Jouve

摘要:

流图是时态网络数据的一种非常有用的表示模式,其丰富性提供了广泛的可能方法。各种方法,旨在推广的经典方法适用于静态网络正在不断改进。在本文中,我们描述了一个框架,扩展到流图迭代加权丰富俱乐部特征的静态网络中提出的[1]。一般原则是,我们不再考虑节点在整个时间段内对其中一个加权富俱乐部的成员资格,而是将每个节点与时间轮廓相关联,该时间轮廓是节点对整个时间段内出现、消失和变化的加权富俱乐部的连续成员资格的串联。这些配置文件的聚类提供了建立一个典型的时间配置文件的简化列表,从而更深入地了解网络的时间结构的可能性。这种方法是通过记录不同学生在各自学校之间的互动产生的真实世界的数据进行测试。[1]M.杰拉比湾Jouve和F.安布拉德网络中的稠密和稀疏顶点连通性。Journal of Complex Networks,8(3),2020。

英文摘要:

Stream graphs are a very useful mode of representation for temporal network data, whose richness offers a wide range of possible approaches. The various methods aimed at generalising the classical approaches applied to static networks are constantly being improved. In this paper, we describe a framework that extend to stream graphs iterative weighted-rich-clubs characterisation for static networks proposed in [1]. The general principle is that we no longer consider the membership of a node to one of the weighted-rich-clubs for the whole time period, but each node is associated with a temporal profile which is the concatenation of the successive memberships of the node to the weighted-rich-clubs that appear, disappear and change all along the period. A clustering of these profiles gives the possibility to establish a reduced list of typical temporal profiles and so a more in-depth understanding of the temporal structure of the network. This approach is tested on real world data produced by recording the interactions between different students within their respective schools. [1] M. Djellabi, B. Jouve, and F. Amblard.
