The Hidden Cluster Problem on a random graph is defined as follows: given a graph randomly drawn from a distribution G(n,k,p,q) - a graph on n vertices with k clusters, where p denotes the probability of an edge between two vertices within the same cluster, q denotes the probability of an edge between two vertices in different clusters, p > q - the problem is to find the ('hidden') clusters planted in this graph via this distribution.

In this talk, I will sketch Frank McSherry's approach of solving this problem - in his paper "Spectral Partitioning of Random Graphs' he puts two vertices into the same cluster, if the norm of the difference between the columns in the projection matrix corresponding to these vertices is small.
