LSALSA: Accelerated Source Separation via Learned Sparse Coding
Benjamin Cowen, Apoorva Nandini Saridena, Anna Choromanska
We propose an efficient algorithm for the generalized sparse coding (SC) inference problem. The proposed framework applies to both the single dictionary setting, where each data po…
