Community detection and stochastic block models: recent developments

E Abbe - Journal of Machine Learning Research, 2018 - jmlr.org
The stochastic block model (SBM) is a random graph model with planted clusters. It is widely
employed as a canonical model to study clustering and community detection, and provides …

Semi-supervised and un-supervised clustering: A review and experimental evaluation

The computer science and physics of community detection: Landscapes, phase transitions, and hardness

C Moore - arXiv preprint arXiv:1702.00467, 2017 - arxiv.org
Community detection in graphs is the problem of finding groups of vertices which are more
densely connected than they are to the rest of the graph. This problem has a long history, but …
