The Hyperspherical Geometry of Community Detection: Modularity as a Distance

1 code implementation6 Jul 2021 Martijn Gösgens, Remco van der Hofstad, Nelly Litvak

In that sense, modularity-based community detection methods can be seen as a subclass of a more general class of projection methods, which we define as the community detection methods that adhere to the following two-step procedure: first, mapping the network to a point on the hypersphere; second, projecting this point to the set of clustering vectors.
