Yimeng-Zhang/feature-engineering-and-feature-selection

A Guide for Feature Engineering and Feature Selection, with implementations and examples in Python.

43
/ 100
Emerging

Covers the complete feature engineering pipeline from data exploration through selection, including univariate/bivariate analysis, missing value imputation, outlier detection, encoding, and dimensionality reduction techniques. Implementations leverage scikit-learn and pandas with Jupyter notebook demos that explain the rationale and trade-offs for each method. The guide emphasizes practical decision-making—when and why to apply specific techniques—rather than just algorithmic implementations.
