主成分分析数据处理方法探讨

The Discussion on Improved Methods of the Principal Component Analysis

本文针对传统主成分分析的不足,分析了做主成分分析前对数据进行预处理的必要性,并对数据的预处理方法进行了探究,提出了"初始化"方法实现无量纲化处理数据的目的.最后结合具体实例证实了改进方法的优越性.

Against weaknesses of traditional principal component analysis method, this paper analyses the necessity of processing the data in advance. Then we discusse the process methods and of-fersome improved methods. At last it gives an example to prove the superiority of improved methods.
