Title: PCA求解输出投影矩阵 Download
Description: PCA (principal component analysis), or principal component analysis, is one of the most widely used data dimensionality reduction algorithms. The main idea of PCA is to map the n-dimensional feature to the k-dimensional feature, which is a new orthogonal feature, also known as the main component. It is a k-dimensional feature reconstructed on the basis of the original n-dimensional feature.
