Standardizing Data Set Terminology for Effective Communication in Medical Artificial Intelligence Research

Core Concepts

Harmonizing data set terminology between medical and artificial intelligence research fields is crucial for effective communication and collaboration in the rapidly evolving field of medical AI.

Abstract

This narrative review examines the historical evolution of data set terminology in both the medical and artificial intelligence (AI) research fields, highlighting the importance of clear and standardized terminology for effective communication and collaboration in the rapidly growing field of medical AI.
The review begins by tracing the divergent development of data set terminology in the AI and medical research domains. In AI research, the common framework of "training set," "validation set," and "test set" has been widely adopted, while in traditional medical research, the term "validation" has been used to refer to the final testing of a developed model.
The review then explores examples of prominent medical AI studies that have exhibited terminological inconsistencies, leading to potential misunderstandings and methodological discrepancies. To address this issue, the review recommends the adoption of standardized AI-centric terminology, such as "training set," "validation (or tuning) set," and "test set," along with explicit definitions of these terms in each research publication.
Additionally, the review delves into the various categories of test sets used in AI evaluation, including internal testing (random splitting, cross-validation, and leave-one-out) and external testing (temporal and geographic sets). Understanding these test set classifications is crucial for assessing the robustness and generalizability of AI applications in medicine.
The harmonization of data set terminology between medical and AI research is critical for advancing the field of medical AI. By adopting standardized terminologies and ensuring their clear definition in research publications, the review aims to foster more effective communication and collaboration across disciplines, ultimately contributing to the ethical and effective deployment of AI in clinical settings.

Deeper Inquiries

How can the standardization of data set terminology in medical AI research be effectively implemented and adopted across the broader scientific community?

Standardizing data set terminology in medical AI research can be effectively implemented and adopted across the broader scientific community through several key strategies:

Consensus Building: Engaging stakeholders from both the medical and AI research fields to establish a common understanding of the importance of standardized data set terminology. This can involve organizing workshops, conferences, and collaborative initiatives to discuss and agree upon the terminology to be used.

Guidelines and Best Practices: Developing clear guidelines and best practices for data set terminology in medical AI research. These guidelines should outline the standardized terms to be used (such as 'training set,' 'validation set,' and 'test set') and provide explicit definitions for each term.

Education and Training: Providing education and training programs for researchers, practitioners, and students in both fields to ensure they are familiar with and understand the standardized data set terminology. This can help in promoting consistent usage of terms in research publications.

Integration in Publication Standards: Encouraging journals and publications in the medical and AI fields to adopt standardized data set terminology as part of their publication standards. This can help in promoting consistency and clarity in research reporting.

Collaborative Research Projects: Encouraging collaborative research projects between medical and AI researchers that emphasize the use of standardized data set terminology. By working together on projects, researchers can learn from each other and adopt common terminology practices.

Continuous Monitoring and Feedback: Establishing mechanisms for monitoring the adoption of standardized data set terminology and collecting feedback from researchers on its effectiveness. This feedback can help in refining and improving the standardized terminology over time.

How might the potential barriers to achieving a universal consensus on data set terminology be overcome?

Several potential barriers may hinder the achievement of a universal consensus on data set terminology in medical AI research. These barriers can be overcome through the following strategies:
