%description
Provides an l1-version of the spectral clustering algorithm devoted to
robustly clustering highly perturbed graphs using l1-penalty. This
algorithm is described with more details in the preprint C. Champion, M.
Champion, M. Blazère, R. Burcelin and J.M. Loubes, "l1-spectral clustering
algorithm: a spectral clustering method using l1-regularization" (2022).
