摘要
首先对主成分分析应用中出现的一些误区,通过推导指出错误所在,并提出相应的改进方案.最后通过一个实例,说明新方案的合理性.
Against to the frequent mistakes emerged from the application of the Principle Component Analysis, this article has deduced the errors, and suggested the reformative schemes correspondingly. The rationality of new schemes is affirmed by an example in the end.
