#multi-agent reasoning #consistency verification #uncertainty calibration #medical QA #AI reliability
📌 Key Takeaways
- Multi-agent reasoning with consistency verification enhances uncertainty calibration in medical multiple-choice question answering.
- The approach improves model reliability by cross-verifying answers among multiple reasoning agents.
- It addresses overconfidence issues in AI systems used for medical decision-making.
- The method demonstrates better performance on medical QA benchmarks compared to single-agent models.

Abstract: Miscalibrated confidence scores are a practical obstacle to deploying AI in clinical settings. A model that is always overconfident offers no useful signal for deferral. We present a multi-agent framework that combines domain-specific specialist agents with Two-Phase Verification and S-Score Weighted Fusion to improve both calibration and discrimination in medical multiple-choice question answering. Four specialist agents (respiratory, cardiology,
