Abstract:

Analysis of networks and in particular discovering communities in networks has been a focus of recent work in several fields, with applications ranging from friendship networks to food webs. Nonetheless, there is a certain amount of disconnect between the many algorithms proposed for community detection, the probability models for random graphs that are often over-simplified but easily tractable, and the complex features we observe in real networks. The talk will review some common methods and models for community detection, and present new models and methods that allow for more flexible network structures. Both empirical results and asymptotic theory will be used to assess performance.
