Abstract
Described is a system for automated artifact removal to generate a clean signal. During operation, the system selects initial noise components from a multi-channel, pre-processed signal by performing independent component analysis decomposition on the pre-processed signal to separate and rank the independent components as noise components. A clean signal is then generated through optimized selection of the noise components based on a signal quality index in which the noise components are moved from the original pre-processed signal until a sufficient signal quality is received.
