Table 1 Comparison of the reconstruction errors. The error is calculated using the signal energy-based measure introduced in (5) for all 19 ICA's components (ICA), 5 classificatory decomposition components determined by the algorithm as important for classification and at the same time "improved" for reconstruction (CD 5), and the prototypical 5 components (determined by similarities in shape) taken directly from ICA without an "improvement" (ICA 5).
