Copied to clipboard
| Challenge: | Existing approaches to QA provide inaccurate answers but lack mechanisms to iteratively refine poor queries. |
| Approach: | They propose a biomedical question answering agent that performs self-critic query refinement . they propose re-reflection methods that kick in only after full retrieval is completed . |
| Outcome: | a biomedical question answering agent achieves 78.32% accuracy on PubMedQA . the proposed approach provides practical assistance to clinicians and biomedically researchers . |
