主分量分析
The main difference between ICA and PCA(Principal Component Analysis)or SVD(Singular Value Decomposition) is that the components decomposed by the later method are only mutually uncorrelated,whereas the components decomposed by the former method are mutually independent statisically.
ICA與 PCA(主分量分析 )或 SVD(奇異值分解 )的主要不同是 :后者分解得的各分量只是互不相關(guān) ,而前者則要求各分量相互統(tǒng)計獨立。
