Figure 4
Classification quality for all subjects during training and test sessions, as measured by value .
Classification quality during training is displayed on left panes A and C, quality during test is presented on panes B and D. The first row of columns corresponding to the 4th day (4a) represents values computed from data for 16 EEG electrodes, and the second one (4b) represents the values computed from data for all 24 EEG electrodes. Notice that each column exceeds the level p = 0.33 related to random classifying.
