Title Uncovering hidden block structure
Abstract We develop a multistage procedure for uncovering the block structure in a matrix. Our algorithm combines standard combinatorial techniques with a novel clustering approach that merges both numerical and structural analysis. A central part of our process is to use a doubly stochastic scaling. We illustrate the use of our algorithm in partitioning sparse matrices for constructing a preconditioner for iterative methods. We also show how we can use our approach in community detection in both undirected and directed networks.
