Feature selection frequency. Relative frequency of selection for all four subjects per EEG channel (A) and projected on a head model (B). There are clear selection preferences, and although there is high inter-subject variation, FC1, C3 or Cz is highly selected in all subjects. Individual rankings have been scaled to the range [0 1], and the reported results are from the linear filter method.
