SOFTWARE IMPLEMENTATIONS:
 ICA COMPARISONS

General Description

This software implementation included here is related to our paper presented at a conference [GaKi05]. It evaluates the sensitivity to outliers of the following five independent component analysis (ICA) algorithms:

  1. FastICA;
  2. Extended-Infomax;
  3. JADE;
  4. Radical-ICA; and
  5. Beta-divergence.

The sensitivity to outliers is evaluated using the following measures:

  1. The Amari separation performance index;
  2. The optimum angle of rotation error; and
  3. The contrast function difference.

The signal to be demixed by the ICA is a simulated outlier-contaminated mixture of sources. This zip file contains the Matlab code used to generate the results for that paper.
