Research output: Contribution to conferencePaper

Abstract

A spatial filter which does not utilize prior and temporal information is proposed for MEG (magnetoencephalography) analysis. Stochastic characteristics of the current density distribution estimated with a spatial filter is considered to improve the estimation. Second and fourth order cumulants are utilized to design a spatial filter. A numerical experiment shows the fourth order cumulants are effective for localization.
