Researches on Modifity of Independent Component Analysis Method

Xia De-shen

Abstract

Independent Component Analysis(ICA)was a new development of signal processing.ICA algorithm and its fast algorithm(FastICA)were introduced.Based on analyzing kernel iteration course of the FastICA algorithm M-FastICA was advanced.M-FastICA improved convergence performance and reduced iterations process.Aimed at the convergent speed of M-FastICA was dependent on initial weights,LM-FastICA was advanced by imported looseness agent,and reduced the dependence on initial weights.
