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...
这次的文章是 A Tutorial on Principal Component Analysis(https://arxiv.org/abs/1404.1100),文章讲解了主成分分析(PCA)的动机与方法。如标题所说,这篇文章严格来说并不是一篇论文,更像一篇 PCA 的教程。 本文使用的符号 感觉这篇文章较为不好的一点是,作者使用的符号在各个小节会改来改去,矩阵的大小一会儿 ...
