xDAWN estimates spatial filters that maximise the signal-to-noise ratio of a target event-related response. The implementation here operates on epoched data and follows the standard generalised-eigenvalue formulation using a target evoked covariance and a residual-noise covariance estimated from class-wise residual epochs.
