Community detection consists in identification of groups of
similar items within a population. In the context of online social
networks, it is a useful primitive for recommending either contacts or
news items to users. We will consider a particular generative
probabilistic model for the observations, namely the so-called
stochastic block model and prove that the non-backtracking operator
provides a significant improvement when used for spectral clustering.
joint work with C. Bordenave and L. Massoulie.
