Supervised fine-tuning with synthetic data may hinder disease prediction. Models perform poorly on real-world tasks.
Florida's lawsuit against OpenAI has brought attention to the potential risks of AI models like ChatGPT, and a new study reveals another challenge in the development of reliable AI systems. Researchers have found that supervised fine-tuning with synthetic rationale data can actually hurt real-world disease prediction. This contradicts the common assumption that such fine-tuning improves language model performance on clinical prediction tasks.
The study, published on arXiv, tested this assumption on five-year Alzheimer's disease prediction and found that models trained with synthetic data performed worse than expected. This matters because AI models are increasingly being used in healthcare to predict diseases and make clinical decisions. If these models are not reliable, it can have serious consequences for patients.
As the development of AI models continues to accelerate, it's essential to watch how researchers and developers respond to these findings. Will they re-evaluate their use of synthetic rationale data, and what alternative methods will they explore to improve the performance of AI models in clinical prediction tasks? The answer to these questions will be crucial in ensuring that AI systems are safe and effective in real-world applications.
