Electrode importances for the classification based on spectral features with logistic regression. Electrodes are shown in a 2D flattened view of the EEG headset (occipital = bottom, frontal = top, left/right temporal = center sides). Background color indicates each electrode’s importance in distinguishing familiar vs. unfamiliar music (yellow = high importance, blue = low).
