Abstract :
This paper analyzes the Kurtosis based ICA method, and presents the geometrical explanation of its principle. Through the analysis of ICA solution process, this paper also explains the reasons for the indeterminacy and probabilistic property of the ICA solution. The analytical results and conclusions can be applied to the studies of other ICA methods.
