py-evoFE is an open-source Python library that uses genetic algorithms to automate and optimize feature engineering for tabular machine learning datasets, with scikit-learn compatibility and Polars for performance.
This cheatsheet provides a quick reference for using the Polars library in Python, covering installation, data structures, and methods for data analysis and transformation.
This article explains why and how fenic extended Polars with Rust expression plugins to perform text operations (chunking, prompt templating, fuzzy matching, etc.) natively in the engine, avoiding performance and composition issues of Python UDFs.
Maxime Rivest announces porting dplyr to Python using polars/duckdb as backend, evaluating it as solid.
A quadriplegic former data scientist built VibeETL, a lightning-fast visual ETL tool powered by Polars and React Flow, designed to replace Alteryx with community extensibility and cloud integration support. The tool is open-source and seeking community testing.
