用结构和动力学信息预测个体之间的相互作用

Predicting interactions between individuals with structural and dynamical information

Thibaud Arnoux, Lionel Tabourier, Matthieu Latapy

摘要:

捕获交互的结构和时间方面对于许多真实世界的数据集(如个人之间的联系)至关重要。使用链接流的形式主义,以捕捉系统的动态,我们解决了链接流中的活动预测的问题,也就是说,预测在给定的时间段内发生的链接的数量,我们提出了一个协议,利用包含在链接流的时间和结构信息。使用监督学习方法,我们能够对系统的动态进行建模以提高预测。我们研究了我们的算法的行为和影响预测的关键因素。通过引入不同类别的节点对,我们能够提高质量,并增加我们的预测的多样性。

英文摘要:

Capturing both the structural and temporal aspects of interactions is crucial for many real world datasets like contact between individuals. Using the link stream formalism to capture the dynamic of the systems, we tackle the issue of activity prediction in link streams, that is to say predicting the number of links occurring during a given period of time and we present a protocol that takes advantage of the temporal and structural information contained in the link stream. Using a supervised learning method, we are able to model the dynamic of our system to improve the prediction. We investigate the behavior of our algorithm and crucial elements affecting the prediction. By introducing different categories of pair of nodes, we are able to improve the quality as well as increase the diversity of our prediction.
