Abstract
En 中文
• Prior knowledge of P300 spatial weights is modeled with a multivariate Gaussian. • A novel Subject-Independent Electrode Placement (SIEP) allows cross-dataset transfer. • Updating the prior with partial subject-specific data achieves near-optimal accuracy. • Methods provide flexible control over the performance vs. simplicity trade-off.
