MEG Beamforming using Bayesian PCA for Adaptive Data Covariance Matrix Regularisation

Beamformers are a commonly used method for doing source localisation from magnetoencephalography (MEG) data. A key ingredient in a beamformer is the estimation of the data covariance matrix. When the noise levels are high, or when there is only a small amount of data available, the data covariance m...
