Table 2 Comparison of the generalization errors. The mean generalization errors (EMSE) are computed for the vectors of coefficients found by the presented classificatory decomposition method (CD) and ICA. The P-value represents the significance level of the fact that the presented method produces components that are more convenient for classification (P-value ≤ 0.05 implies statistical significance). The errors were averaged over 10 trials for each CD method.
