多层网络数据的潜在空间模型

A Latent Space Model for Multilayer Network Data

Juan Sosa, Brenda Betancourt

摘要:

在这项工作中,我们提出了一个贝叶斯统计模型,同时表征两个或两个以上的社交网络定义在一个共同的演员集。该模型的关键特征是分层先验分布,使我们能够联合表示整个系统,实现依赖和独立网络之间的折衷。除此之外,这样的规范很容易让我们在低维欧氏空间中可视化多层网络数据,生成反映参与者之间共识亲和力的加权网络,建立网络之间相关性的度量,评估主体对参与者之间关系的认知判断,并在不同的社会实例中执行聚类任务。我们的模型的能力说明使用几个现实世界的数据集,考虑到不同类型的演员,大小和关系。

英文摘要:

In this work, we propose a Bayesian statistical model to simultaneously characterize two or more social networks defined over a common set of actors. The key feature of the model is a hierarchical prior distribution that allows us to represent the entire system jointly, achieving a compromise between dependent and independent networks. Among others things, such a specification easily allows us to visualize multilayer network data in a low-dimensional Euclidean space, generate a weighted network that reflects the consensus affinity between actors, establish a measure of correlation between networks, assess cognitive judgements that subjects form about the relationships among actors, and perform clustering tasks at different social instances. Our model's capabilities are illustrated using several real-world data sets, taking into account different types of actors, sizes, and relations.
