Basic Encoding Techniques (Simple transformation of categories into numbers) • One-hot encoding • Label encoding • Ordinal encoding 2. Target-Based Encoding (Encoding based on relationship with the target variable) • Target Encoding (Mean Encoding) • Target Mean Encoding with k-fold Cross-validation • Leave-One-Out Encoding • Bayesian Encoding • James-Stein Encoding • M-estimator Encoding • Smooth Target Encoding • Probability Ratio Encoding 3. Frequency or Count Based Encoding (Using counts or frequency of categories) • Frequency Encoding • Count Encoding 4. Binary and Hash Encoding Methods (Represent categories in binary or hash form) • Binary Encoding • Hash Encoding • Geohash Encoding • Gray Encoding • BaseN Encoding 5. Mathematical or Statistical Encoding (Using mathematical or statistical models) • Effect Encoding (Deviation Encoding) • Backward Difference Encoding • Polynomial Encoding • Generalized Linear Mixed Models (GLMM) • Kernel Feature Maps • Principal Component Encoding (PCA-based encoding) • Regularized Encoding • Weight of Evidence (WOE) Encoding • CatBoost Encoding 6. Decision Tree-Based Encoding (Using decision trees for encoding) • Decision Tree Encoding 7. Encoding for Special Scenarios (Handling special data types or cases) • Thermometer Encoding • Rank Hot Encoding • Sum Encoding • Quantile Encoding • Similarity Encoding • Time-based Encoding • Rare Category Encoding • Entity Embedding 8. Advanced Encoding (More complex or rarely used methods) • Facet Encoding • Difference Encoding (Helmert Encoding) For more videos on categorical variable encoding, you can bookmark this playlist: https://youtube.com/playlist?list=PLS...
