Original Kurzfassung:
We introduce a novel way to incorporate priorinformation into (semi-) supervised non-negative matrixfactorization, which we call differentiable dictionarysearch. It enables general, highly flexible and principledmodelling of mixtures where nonlinear sources are linearlymixed. We study its behavior on an audio decompositiontask, and conduct an extensive, highly controlled study ofits modelling capabilities
