Intrinsic dimension estimation via nearest constrained subspace classifier
A new classifier called NCSC and its fast version called NCSC-II are proposed. Classifiers of NN, NFL and NS are the special cases of NCSC. NCSC/NCSC-II can be used as intrinsic dimension estimator. Using well-tuned intrinsic parameter, NCSC/NCSC-II outperforms NN, NFL and NS.
