explore the EEG source localization problem as the estimation of current dipoles. We formulate the relation between current dipoles and EEG observation by state-space model and consider birth-death process of current dipole. In this study, the location and moment of dipoles are estimated by Rao-Blackwellized Particle Filter (RBPF) and whether a new dipole is born or an existed dipole disappears is estimated by Bayesian Information Criterion (BIG). We propose a new dipole birth-death model for BIG model selection.
