Auto-Prep: Holistic Prediction of Data Preparation Steps for Self-Service Business Intelligence

Summary: Auto-Prep jointly predicts data transformations and joins for self-service BI, recognizing their interdependence and modeling workflows via a Steiner-tree-inspired graph algorithm with quality guarantees. On ~2K real projects, it predicts over 70% of steps, outperforming prior methods and GPT-4. (summarized by gpt-5.6-luna on Jul 24 2026)
