py-evoFE: Automated evolutionary feature engineering for tabular ML
tanopereira · reddit · 2026-08-28
py-evoFE (v0.3.0) is an open-source Python library using genetic algorithms for automated feature engineering in tabular ML.
Key Features:
- Hierarchical Chaining: Evolved features become building blocks for complex nested transformations.
- 40+ Transformers: Includes non-linear arithmetic, target encoding, dimensionality reduction (PCA/UMAP), and graph clustering.
- Performance: Vectorized via Polars/PyArrow; uses matrix hashing to cache stateful projections (e.g., UMAP) and eliminate redundant computation.
- Scikit-Learn Compatible: Implements standard fit/transform APIs for easy pipeline integration.
- Interactive Viewer: Generates a standalone HTML dashboard to visualize the evolutionary search process.
