Feature extraction is different from feature selection, and feature extraction is to extract the abstract features contained in original features according to certain algorithms based on the original features.
PCA (principal component analysis)PCA is a kind of unsupervised feature dimensionality reduction method. Specifically, PCA is not a feature-reduced method, and PCA searches for a set of orthogonal mapping spaces at a time and makes it possible to
