Figure 4

Results of FDA: (A) shows the visualization of all samples via PCA and FDA from a 144-dimensional original feature space, which consists of slope and intercept parameters for 9 frequency bands and 8 experimental condition days; (B) shows the visualization of weighting parameter obtained by FDA for two classification objectives. Individual bar plots depict the horizontal or vertical sums of the absolute values of classification outcomes; (C) shows the matrices of rounded averages of classification rates via 10-fold CV for all combinations of experimental conditions and sub-bands in each classification objective.
