We develop collaborative topic Poisson factorization (CTPF), a generative model of articles and reader preferences.

We evaluate the link prediction accuracy of our algorithm on eight real-world networks with up to 60, 000 nodes, and 24 benchmark networks.

In large social networks, we expect entities to participate in multiple communities, and the number of communities to grow with the network size.

Our approach is based on a Bayesian model of networks that allows nodes to participate in multiple communities, and a corresponding algorithm that naturally interleaves subsampling from the network and updating an estimate of its communities.

We develop a scalable algorithm for posterior inference of overlapping communities in large networks.
