Abstract
A system and method are provided for distinguishing between a plurality of sources based upon unconstrained acoustic signals captured therefrom. A spectrographic transformation is applied to time-captured segments of acoustic signals to generate a spectral vector for each. A selectively executed sparse decomposition includes in a training system mode simultaneous sparse approximation upon a joint corpus of spectral vectors for a plurality of acoustic signal segments from distinct sources. At least one sparse decomposition is executed for each spectral vector in terms of a representative set of decomposition atoms. Discriminant reduction executes during the training system mode to down-select from the representative set an optimal combination of atoms for cooperatively distinguishing acoustic signals emitted by different distinct sources. Classification is subsequently executed upon the sparse decomposition of an input acoustic signal segment unit to discover a degree of correlation for the input acoustic signal segment relative to each distinct source.
