摘要 介绍了独立分量分析的基本理论和算法,在快速分离算法基础上提出了一种基于改进的牛顿迭代法的独立分量分析算法。仿真结果表明,改进的算法在分离效果相当的情况下,减少了迭代次数,提高了收敛速度,用于实时处理和解决高维问题有显著的优越性。 The basic theory and algorithm of Independent Component Analysis (ICA) are introduced, A new ICA based on Newton's iteration method is proposed. The simulation shows that this improved algorithm is effective.
