1. Abstract
This paper conducts a comprehensive survey on data quality (DQ) evaluation and improvement tools for machine learning (ML). It emphasizes the critical role of high-quality data in ML model performance, fairness, robustness, safety, and scalability. The paper introduces four DQ dimensions (intrinsic, contextual, representational, and accessibility) and twelve metrics specific to ML, providing definitions and examples.
The survey reviews seventeen open-source DQ tools released in the past five years, analyzing their strengths and limitations based on the DQ dimensions and metrics. It proposes a roadmap for developing new DQ tools, highlighting the importance of integrating automation, monitoring, and AI technologies. The paper also discusses emerging trends like large language models (LLMs) and generative AI in DQ evaluation and improvement, showcasing their potential applications and future directions.
