Abstract
A computer-implemented method according to one embodiment includes creating a clean dictionary, utilizing a clean signal, creating a noisy dictionary, utilizing a first noisy signal, determining a time varying projection, utilizing the clean dictionary and the noisy dictionary, denoising a second noisy signal, utilizing the time varying projection, and expanding the clean dictionary and the noisy dictionary by updating the clean dictionary and the noisy dictionary to include new clean spectro-temporal building blocks and new noisy spectro-temporal building blocks created utilizing additional clean and noisy signals.
