动态网络社区发现的潜在空间方法

Latent Space Approaches to Community Detection in Dynamic Networks

Daniel K. Sewell, Yuguo Chen

摘要:

长期以来,将二元数据嵌入到潜在空间中一直是对各种网络建模的流行方法。虽然聚类已经完成了使用这种方法的静态网络,本文给出了两种方法的社区检测动态网络数据中,建立在距离和投影模型先前提出的文献。我们提出的方法捕捉随时间变化的数据方面,可以建模有向或无向的边缘,固有地将传递性和帐户每个演员的个人倾向,形成边缘。我们提供贝叶斯估计算法,并将这些方法应用于排名动态友谊网络和世界出口/进口数据。

英文摘要:

Embedding dyadic data into a latent space has long been a popular approach to modeling networks of all kinds. While clustering has been done using this approach for static networks, this paper gives two methods of community detection within dynamic network data, building upon the distance and projection models previously proposed in the literature. Our proposed approaches capture the time-varying aspect of the data, can model directed or undirected edges, inherently incorporate transitivity and account for each actor's individual propensity to form edges. We provide Bayesian estimation algorithms, and apply these methods to a ranked dynamic friendship network and world export/import data.
