Center node: "the continuous configuration model a null for community detection on weighted networks"
  Abstract: Community detection is the process of grouping strongly connected nodes in a network. Many community detection methods for un-weighted networks have a theoretical basis in a null model, which provides an interpretation of resulting communities in terms of statistical significance. In this paper, we introduce a null for sparse weighted networks called the continuous configuration model. We prove a Central Limit Theorem for sums of edge weights under the model, and propose a community extraction method called CCME which combines this result with an iterative multiple testing framework. To benchmark the method, we provide a simulation framework that incorporates the continuous configuration model as a way to plant null or "background" nodes in weighted networks with communities. We show CCME to be competitive with existing methods in accurately identifying both disjoint and overlapping communities, while being particularly effective in ignoring background nodes when they exist. We present two real-world data sets with potential background nodes and analyze them with CCME, yielding results that correspond to known features of the data.
