Pca Quiz Pdf Principal Component Analysis Algorithms The main ideas behind pca are actually super simple and that means it's easy to interpret a pca plot: samples that are correlated will cluster together apart from samples that are not. Tl;dr learn about principal component analysis (pca) in 5 minutes for data dimension reduction and interpretation.
