Quark Medical Alignment: A Holistic Multi-Dimensional Alignment and Collaborative Optimization Paradigm

Researchers propose a new medical alignment paradigm for large language models that addresses the shortcomings of current reinforcement learning approaches in high-stakes medical question answering. The framework introduces a multi-dimensional alignment matrix and unified optimization mechanism to simultaneously optimize correctness, safety, and compliance in medical AI applications.

• →Current reinforcement learning approaches for AI alignment fail in medical contexts due to expensive annotations and lack of absolute correctness measures.
• →The proposed paradigm uses a four-category alignment matrix covering fundamental capabilities, expert knowledge, feedback, and format specifications.
• →A unified optimization mechanism with Reference-Frozen Normalization addresses gradient domination issues from heterogeneous reward signals.
• →The approach implements weakness-oriented, risk-prioritized optimization specifically designed for medical domain requirements.
• →Experimental results show effectiveness in real-world medical scenarios, establishing new standards for vertical domain AI alignment.
