Principal Component and SVD approach
$begingroup$
Can we say PCA (principal component analysis) is the decomposite linear dependent component of matrix U and VT.
So the middle term is so-called feature extraction of the original dataset which is learning independently?
How to choose PC1 and PC2?
thanks
