Table 2. Tabulated results for the so-called [8] ICA “promotional material.”.

Observed Properties and Results (good is ISI <0.1)
Property Source a (sa) Source b (sb)
Negentropy: 0.2753 0.3708
(excess) Kurtosis: 3.0630 3.5225
Algorithm Daubechies Amari (ISI)
FastICA 0.0154 0.0108
Infomax (super) 0.0076 0.0052
Infomax (sub) 1.0758 0.9899
ICA-EBM 0.0059 0.0039

Both Infomax (super) and FastICA do successfully separate (zero ISI indicates perfect separation) the super-Gaussian sources Inline graphic and Inline graphic. Note the excess kurtosis is more than 3 for both sources. Numbers in boldface indicate when separation was good.
