Dimension reduction: Additional benefit of an optimal filter for independent component analysis to extract event-related potentials

► An optimal filter (OF) conforms to the linear superposition rule. ► An OF is designed according to the temporal and spectral properties of a desired ERP. ► An OF does not change coefficients of the linear transformation model of ERP data. ► Number of sources in ERP data may be reduced by an OF. ►...
