Reliable gradient search directions for kurtosis-based deflationary ICA: Application to physiological signal processing.Efficient gradient search directions for the optimisation of the kurtosis-based deflationary RobustICA algorithm in the case of real-valued data are proposed in this paper.  The proposed scheme inherits the exact line search of the conventional RobustICA for which a good convergence property through a given direction is guaranteed.
