    Multiway Spectral Clustering with Out-of-Sample Extensions through Weighted Kernel PCA
    Download  www.esat.kuleuven.be
    —A new formulation for multiway spectral clustering is proposed. This method corresponds to a weighted kernel principal component analysis (PCA) approach based on primal-dual lea...

    Constrained 1-Spectral Clustering
    Download  jmlr.csail.mit.edu
    An important form of prior information in clustering comes in form of cannot-link and must-link constraints. We present a generalization of the popular spectral clustering techniq...
