动态无限混合成员随机块模型

Dynamic Infinite Mixed-Membership Stochastic Blockmodel

Xuhui Fan, Longbing Cao, Richard Yi Da Xu

摘要:

定向和成对测量通常用于对社交网络设置中的相互关系进行建模。Mixed-Membership Stochastic Blockmodel(MMSB)是这一领域的开创性工作,其许多功能从那时起得到了扩展。在本文中,我们提出了\emph{Dynamic Infinite Mixed-Membership stochastic blockModel (DIM3)},一个通用的框架,扩展现有的工作,潜在的无限数量的社区和混合成员的网络的每个节点。这个模型是在一个动态的设置,其中引入了额外的模型参数,以反映一个人的成员资格之间的持续程度在连续的时间。因此,两个有效的后验抽样策略和他们的结果,使用合成和真实的数据。

英文摘要:

Directional and pairwise measurements are often used to model inter-relationships in a social network setting. The Mixed-Membership Stochastic Blockmodel (MMSB) was a seminal work in this area, and many of its capabilities were extended since then. In this paper, we propose the \emph{Dynamic Infinite Mixed-Membership stochastic blockModel (DIM3)}, a generalised framework that extends the existing work to a potentially infinite number of communities and mixture memberships for each of the network's nodes. This model is in a dynamic setting, where additional model parameters are introduced to reflect the degree of persistence between one's memberships at consecutive times. Accordingly, two effective posterior sampling strategies and their results are presented using both synthetic and real data.
