Principal Component Analysis (PCA)
This video is gentle and motivated introduction to Principal Component Analysis (PCA). We use PCA to analyze the 2021 World Happiness Report published 2021 and discover what makes countries truly happy. :) References: Scikit-Learn User Guide : https://scikit-learn.org/stable/modul...
