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, and denoising a second noisy signal, utilizing the time varying projection.

Denoising a signal

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.

According to one embodiment, a computer program product for denoising a signal comprises a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, and where the program instructions are executable by a processor to cause the processor to perform a method comprising creating, utilizing a processor, a clean dictionary, utilizing a clean signal, creating, utilizing the processor, a noisy dictionary, utilizing a first noisy signal, determining, utilizing the processor, a time varying projection, utilizing the clean dictionary and the noisy dictionary, and denoising, utilizing the processor, a second noisy signal, utilizing the time varying projection.
