Featuretools
Featuretools is an open-source Python library for automated feature engineering, originally developed by Feature Labs and now maintained by Alteryx. It enables data scientists to efficiently generate rich features from structured and relational data using a method called “deep feature synthesis.”
Key Features
Automated Feature Engineering: Quickly creates hundreds of features from raw data.
Deep Feature Synthesis (DFS): Captures complex patterns across multiple related tables.
Custom Primitives: Define reusable feature logic tailored to specific use cases.
Python-Native: Integrates with pandas, scikit-learn, and ML pipelines.
Scalable: Compatible with Dask for larger datasets and distributed computing.
Example Use Cases
Generating structured inputs from relational databases
Enhancing model performance with automated, domain-aware features
Embedding feature engineering into AutoML workflows
Reproducible feature pipelines for production environments
