    Generalization of the K-SVD algorithm for minimization of ß-divergence 
    García Mollá, Víctor Manuel; San Juan-Sebastian, Pablo; Virtanen, T.; Vidal Maciá, Antonio Manuel; Alonso-Jordá, Pedro (Elsevier, 2019)
    [EN] In this paper, we propose, describe, and test a modification of the K-SVD algorithm. Given a set of training data, the proposed algorithm computes an overcomplete dictionary by minimizing the ß-divergence () between ...
