Abstract :
The technique of Independent component analysis can be applied in image processing, communication processing, data mining and many others. By research on score function of informax algorithm and the performance of Ext-informax algorithm while the sources include impulse signals and Gaussian signals. The results show these algorithms are not stably in these instances. A new score function according to cumulative probability distribution function of signal is proposed. All simulations show better performance than Ext-Informax algorithm under above instances.
