Core Concepts
FEATAUG proposes a novel feature augmentation framework that automatically extracts predicate-aware SQL queries from one-to-many relationship tables, outperforming baselines in effectiveness.
Abstract
FEATAUG addresses the critical problem of feature augmentation from one-to-many relationship tables by automatically extracting predicate-aware SQL queries. It introduces optimizations such as Bayesian Optimization and warm-up strategies to enhance the search process. The framework demonstrates superior performance compared to traditional ML models and deep learning models on real-world datasets.
Stats
Featuretools generates 40 features for evaluation.
FEATAUG selects 8 query templates and 5 predicate-aware SQL queries per template.
