Faster P300 Classifier Training Using Spatiotemporal Beamforming
Benjamin Wittevrongel, Marc M. Van Hulle · International Journal of Neural Systems · 2016
The linearly-constrained minimum-variance (LCMV) beamformer is traditionally used as a spatial filter for source localization, but here we consider its spatiotemporal extension for P300 classification. We compare two variants and show that the spatiotemporal LCMV beamformer is at par with state-of-the-art P300 classifiers, but several orders of magnitude faster in training the classifier.
