Blind Source Separation in Ultra-Low Power Devices
Blind Source Separation (BSS) is the process of decomposing a mixed signal into a set of linearly independent vector components. The Blind Source Separation problem arises organically in day-to-day human interaction in the form of the Cocktail Party Problem: when found in an auditory environment characterized by simultaneous speakers (say speaker A and speaker B), a human can narrow their auditory attention to a single target source (speaker A) and ignore all other sources (speaker B). While seemingly trivial for a human, this task has historically proven to be difficult to solve algorithmically. ...
