Improved FastICA algorithm with fifth-order convergence
Xuansen He · Computer Engineering and Applications Journal · 2012
FastICA algorithm is optimized by the quadratic convergence of Newton iteration method and is widely applied in BBS.In order to accelerate the convergence speed of the algorithm,this paper gives two improved FastICA algorithms which use the fifth-order convergence of Newton iterative method.The experimental results show the performance of the improved algorithms is better than that of the FastICA.
