Abstract
Embodiments disclosed herein directed to systems, apparatuses, and methods for the suppression of artifacts in non-invasive electromagnetic recordings. A data set, such as an electroencephalography (EEG) or magnetoencephalography (MEG) data set may be recorded by a number of sensors. The data set may include contributions from a signal of interest and from artifacts. The contribution of artifacts may be suppressed by splitting the data set into projected data and residual data based on a spatial model of the signal of interest. The projected data may contain contributions from the signal of interest and artifacts, while the residual data may primarily contain contributions from artifacts. The projected and residual data may be compared to remove or reduce the contribution of artifacts from the projected data.
