Effect of power feature covariance shift on BCI spatial-filtering techniques: A comparative study

•This study investigates the performance of several spatial-filtering approaches on calibration and test set acquired 30 min after the calibration, mimicking the real BCI scenarios.•EEG extracted feature covariance shifts lead to the BCI model accuracy deterioration, even after 30 min of a break.•FB...
