(a) Importance of each feature type for all subjects, (b) importance of each feature type for the seven best subjects (in terms of classification accuracy), (c) importance of each of the 25 channels in data set 1 for all subjects, and (d) importance of each of the 25 channels in data set 1 for the seven best subjects (in terms of classification accuracy). RP: readiness potential or early CNV/BP, NS: negative slope or late CNV/BP, and PN: peak negativity. The bars indicate ±1 × standard deviation.
