What is Reproducibility in Artificial Intelligence and Machine Learning Research?

In the rapidly evolving fields of Artificial Intelligence (AI) and Machine Learning (ML), the reproducibility crisis underscores the urgent need for clear validation methodologies to maintain scientific integrity and encourage advancement. The crisis is compounded by the prevalent confusion over validation terminology. Responding to this challenge, we introduce a validation framework that clarifies the roles and definitions of key validation efforts: repeatability, dependent and independent reproducibility, and direct and conceptual replicability. This structured framework aims to provide AI/ML researchers with the necessary clarity on these essential concepts, facilitating the appropriate design, conduct, and interpretation of validation studies. By articulating the nuances and specific roles of each type of validation study, we hope to contribute to a more informed and methodical approach to addressing the challenges of reproducibility, thereby supporting the community's efforts to enhance the reliability and trustworthiness of its research findings.
