From Convolutional Sparse Coding To *-NMF Factorization of Time-Frequency Coefficients

Convolutional Dictionary Learning (CDL) is a dictionary learning technique exploiting the translation invariance of elementary signals. In the time-frequency domain, the repetition of elementary frequency patterns can be exploited through the "nonnegative matrix factorization" (NMF) decompositions a…
