Electroencephalography (EEG) has become one of the most popular brain imaging tools. We develop a graph Laplacian-based model for discriminative EEG brain source imaging that takes into account the label information (happiness, sadness, surprise, etc). In addition, we also incorporate some regularization terms, such as L1 norm, total variation, and nuclear norm (low rank) to further improve the results. Simulated experiments show the effectiveness of the proposed framework.
