An error analysis of a direct reconstruction method for the EEG inverse source problem(Algorithms for Matrix・Eigenvalue Problems and their Applications, <Special Issue>Joint Symposium of JSIAM Activity Groups 2005)

Abstract

In this paper, we present an error analysis of a direct reconstruction method for the EEG inverse source problem. Using the Green formula and weighting harmonic functions, the inverse source problem is reduced to a generalized eigenvalue problem. We analyze the stability of the generalized eigenvalue problem and show that the accuracy of the solution can be evaluated by the noise level, the source positions and intensities.
