| 摘 要： | 基于二阶统计特性的主分量分析(PCA)和基于高阶统计特性的独立分量分析(ICA)是两种非常典型的多维统计分析方法.本文对PCA和ICA基本原理进行了简单介绍,并结合脑电消噪问题,对两种方法的性能和特点进行了比较.实验结果表明,在脑电消噪和特征增强等方面,独立分量分析方法具有明显的优势.

| Abstract: | Principle Component Analysis(PCA) and Independent Component Analysis(ICA) are two representative of multivariate data analysis methods , The first is a decorrelation-based method and only uses 1st and 2nd order statistics of random variables; the second is a independence-based method and use higher-order statistics. The basic theories and algorithms are briefly introduced in this paper. The detailed comparison of PCA and ICA is studied with the application of artifacts removal of EEG. The experiment results show that ICA has obvious advantages in artifacts cancellation and feature enhancement. |
