摘要
为验证基于四阶累积量的fastICA算法的稳定性,根据源信号的统计特性,对该算法进行理论分析,并利用仿真程序进行验证。得出算法在源信号具有相同四阶累积量的情况下,存在局部极值点,导致算法分离失败。
In practice,fastICA does not converge to the correct point for some special cases,so the stability of fastICA algorithm is analyzed.Theoretical analysis shows that local convergence points exist.Simulation results are given to prove the conclusion.
