摘要
在图像处理、通讯技术等信息处理领域中,主成分分析(PCA)和小成分分析(MCA)是很常用的一种方法.给出能同时得到主成分分析或小成分分析所要求的特征值和特征向量的实时算法.
Pdnclpai component analysis (PCA) and minor component analysis (MCA) provide powerful statistical techniques in many information processing fields such as image processing, direction-of-arrivaL problems, communication technology, and so on. A new online coupled algorithm for PCA and MCA which can simultaneously extract the eigenvectors and eigenvalues of the covariance matrix with coupled iterations is obtained.
