Table 2 Comparison of the generalization errors. The mean generalization errors (E MSE ) 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.
Method | E MSE | P-value |
|---|---|---|
CD with max. no. of basis functions = 5 | 1.2817 | < 0.0001 |
CD with max. no. of basis functions = 10 | 0.5605 | < 0.0001 |
CD with max. no. of basis functions = 19 | 2.3545 | 1.0000 |
ICA | 1.4186 | Â |
