文章翻译自Jonathon Shlens的google research,名为A Tutorial on Principal Component Analysis。 首先,说说我怎么看到这个文章的。我最近在读一篇关于主动路噪控制的论文的时候遇到一个疑问。首先需要采集车内噪声(输出)和底盘的18个振动信号(输入),为了实现降低车内噪声的目的,需要振动信号和车内噪声具有较好的相干函数...
Principal Component Analysis Tutorial The main idea ofprincipal component analysis(PCA) is to reduce the dimensionality of a data set consisting of many variables correlated with each other, either heavily or lightly, while retaining the variation present in the dataset, up to the maximum extent. T...
