MMXU: A Multi-Modal and Multi-X-ray Understanding Dataset for Disease Progression (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing datasets and models fail to consider critical aspects of medical diagnostics, authors argue . MMXU enables multi-image questions incorporating both current and historical patient data. |
| Approach: | They propose a dataset for MedVQA that focuses on identifying changes in specific regions between two patient visits. |
| Outcome: | The proposed dataset improves diagnostic accuracy by 20% by integrating historical data. |

| Challenge: | Existing medical benchmarks for diagnostic reasoning are limited in their ability to perform complex tasks. |
| Approach: | They propose to benchmark diagnostic capabilities of large language models to assess their accuracy and generalization bottlenecks. |
| Outcome: | The proposed model achieves 45.82%, 31.09%, and 17.79% accuracy, compared to current models, o3-mini, e1 and DeepSeek-R1 . |
Meta-Tool: Unleash Open-World Function Calling Capabilities of General-Purpose Large Language Models (2025.acl-long)
Copied to clipboard
| Challenge: | Large language models struggle with addressing diverse user inquiries in open-world tasks. |
| Approach: | They propose a plug-and-play tool retrieval system for LLMs to access external tool library and use retrieved tools to solve user's problem. |
| Outcome: | The proposed model improves on a finetuned version of LLaMA-3.1 and 2,800 dialogues and 7,361 tools spanning ten distinct test categories. |
