Abstract
This letter establishes the normalized natural gradient based algorithm in independent component analysis by employing simple matrix algebra. Moreover, another algorithm tightly related to the normalized natural gradient is introduced based on the truncated version of matrix exponentials, strictly restricting solutions in the space of non-singular matrices. Experimental results demonstrate the superior convergence of the proposed algorithms.
