Implementation Codes

NQP: An optimization algorithm for quadratic programming under both cardinality and non-negativity constraints.

NNKSC: The code for Non-negative kernel sparse coding algorithm and its label-consistent extension.

NN-KOMP: The Non-negative kernel-based orthogonal matching pursuit algorithm for sparse reconstruction of signal in the feature space under non-negativity and cardinality constraints.

NN-KLS: The kernelized implementation of the non-negative least-square algorithm (lsqnonneg of Lawson and Hanson) with Cholesky decomposition.

dist-LMNN: The distance-based implementation of large margin nearest neighbor algorithm.
