Researchers have developed DiagLoop, a novel counterfactual data flywheel designed to improve the diagnostic capabilities of large language models. This system generates synthetic training data by varying causes, contexts, and observations, ensuring only valid scenarios are used for training. DiagLoop employs stage-localized reinforcement learning to update specific parts of the model, preventing catastrophic forgetting and enhancing reasoning through symptom abstraction and causal-chain construction. An 8 billion parameter model trained with DiagLoop demonstrated significant improvements in path correctness across industrial systems and disease categories, outperforming conventional baselines and even proprietary references.
