sparsecommunity: Spectral Community Detection for Sparse Networks
Implements spectral clustering algorithms for community detection
in sparse networks under the stochastic block model ('SBM') and
degree-corrected stochastic block model ('DCSBM'), following the methods of
Lei and Rinaldo (2015) <doi:10.1214/14-AOS1274>. Provides a regularized
normalized Laplacian embedding, spherical k-median clustering for 'DCSBM',
standard k-means for 'SBM', simulation utilities for both models, and a
misclustering rate evaluation metric. Also includes the 'NCAA' college
football network of Girvan and Newman (2002) <doi:10.1073/pnas.122653799>
as a benchmark dataset, and the Bethe-Hessian community number estimator
of Hwang (2023) <doi:10.1080/01621459.2023.2223793>.
