About Feature Scaling and Normalization

This technical article provides an in-depth explanation of feature scaling and normalization in machine learning. It covers the concepts of standardization (Z-score normalization) and Min-Max scaling, detailing when and why to use each method. It includes practical implementation using Python's scikit-learn library, discusses the impact on algorithms like PCA and gradient descent, and explains why tree-based methods are scale-invariant.
