A persistent knowledge gap separates Machine Learning (ML) developers from clinicians, limiting the use of ML for clinical data analysis. The study evaluates ChatGPT Advanced Data Analysis (ADA), an extension of GPT-4, as an intuitive bridge for efficient ML method development. Real-world datasets and trial details from large studies across multiple specialties were provided without specific guidance. chatGPT ADA autonomously built state-of-the-art ML models to predict outcomes, matching or exceeding published counterparts. The work supports democratizing ML in medicine by enabling advanced analytics for non-ML experts.

Abstract A knowledge gap persists between Machine Learning (ML) developers (e.g. , data scientists) and practitioners (e.g. , clinicians), hampering the full utilization of ML for clinical data analysis. We investigated the potential of the chatGPT Advanced Data Analysis (ADA), an extension of GPT- 4 , to bridge this gap and perform ML analyses efficiently. Real-world clinical datasets and study details from large trials across various medical specialties were presented to chatGPT ADA without specific guidance. ChatGPT ADA autonomously developed state-of-the-art ML models based on the original study’s training data to predict clinical outcomes such as cancer development, cancer progression, disease complications , or biomarkers such as pathogenic gene sequences. Strikingly, these ML models matched or outperformed their published counterparts. We conclude that chatGPT ADA offers a promising avenue to democratize ML in medicine, making advanced analytics accessible to non-ML experts and promoting broader applications in medical research and practice. Introduction Machine learning (ML) drives advancements in artificial intelligence and is about to transform medical research and practice, especially in diagnosis and outcome prediction 1,2 . Recently, the adoption of ML for analyzing clinical data has expanded rapidly. Today, ML models have an established and evolving role in various areas of public health and medicine, spanning image analysis, public health, clinical-trial performance, and operational organization2. ML models are used in variable contexts such as augmenting medical knowledge , assisting clinicians, or taking on administrative tasks3. Several developments, such as increases in (i) available data generated during clinical care,(ii) available computational processing capacities, and (iii) research activities, favor the more widespread future utilization of ML models in medicine4. However, the complexity of developing, implementing, and validating those models renders them inaccessible to most clinicians and medical researchers5. It also limits their utilization to those people or groups that combine expertise in medicine and data science. Powerful large language models (LLMs) , such as chatGPT’s latest version, GPT-4 (Generative Pre-Trained Transformer-4, OpenAI, CA, US), may soon remedy this situation6. While conversing with humans in plain language, LLMs can reason and perform logical deduction. Recently, the chatGPT Advanced Data Analysis (ADA) has been made available as an extension and beta feature that may be used to analyze data and math problems, create charts, and write, execute, and refine computer code7. Instructing chatGPT ADA can be straightforward, such as“Analyze this patient data and build a machine learning model predicting 12-month mortality rates”. Given this prompt, chatGPT ADA will execute the task and provide feedback on the procedure. However, its validity and reliability in advanced clinical data processing have not yet been evaluated. Our objective is to study the validity and reliability of chatGPT ADA in autonomously developing and implementing ML methods. We included real-world datasets from four large clinical trials of va
