Scalable and Robust Sparse Subspace Clustering Using Randomized Clustering and Multilayer Graphs

no code implementations21 Feb 2018 Maryam Abdolali, Nicolas Gillis, Mohammad Rahmati

To improve the scalability of SSC, we propose to select a few sets of anchor points using a randomized hierarchical clustering method, and, for each set of anchor points, solve the LASSO problems for each data point allowing only anchor points to have a non-zero weight (this reduces drastically the number of variables).
