| Abstract: | An adjusted Chi-Square Statistic is proposed as the measure of dependence of random signals, and this measure is taken as the contrast function of ICA. Taking simulated annealing method the random signal can be separated which can not be separated by parametric method. |
| |
| Keywords: | independent component analysis dependence simulated annealing |
