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 …

establish a formula for the mutual information in statistical inference problems induced by …

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 …

programming formulation is determined by the formulation of the graph colouring …

Rigorous location of phase transitions in hard optimization problems

D Achlioptas, A Naor, Y Peres - Nature, 2005‏ - nature.com
It is widely believed that for many optimization problems, no algorithm is substantially more
efficient than exhaustive search. This means that finding optimal solutions for many practical …
