Four Numeric Scaling Techniques: When to Use Standard, Robust, Power, and Min‑Max

This article explains why numeric feature engineering is essential for machine‑learning models, outlines the two main challenges of differing magnitudes and outliers, and demonstrates four scaling methods—StandardScaler, RobustScaler, PowerTransformer, and MinMaxScaler—using the California housing dataset, complete with code, visualizations, and guidance on when each method is appropriate.
