Spectral estimation for detecting low-dimensional structure in networks using arbitrary null models
Mark D. Humphries, Javier A. Caballero, Mat Evans +2
Discovering low-dimensional structure in real-world networks requires a suitable null model that defines the absence of meaningful structure. Here we introduce a spectral approach…

Finding communities in sparse networks
Abhinav Singh, Mark Humphries
Spectral algorithms based on matrix representations of networks are often used to detect communities but classic spectral methods based on the adjacency matrix and its variants fai…
