| Challenge: | Clinical Decision Support Systems (CDSSs) provide reasoning and inquiry guidance for physicians, yet they face high maintenance costs and low generalization capability. |
| Approach: | They propose a clinical diagnostic model with clinical reasoning and inquiry skills, the Dr. Assistant, and a pipeline to capture abstract reasoning logic. |
| Outcome: | The proposed model outperforms open-source models and achieves competitive performance to closed-source model. |

| Challenge: | Large Language Models (LLMs) are extremely popular, leading to a race towards reducing their inference costs. |
| Approach: | They propose a method that quantizes weights and activations to 4 bits to achieve better accuracy. |
| Outcome: | The proposed method reduces runtime costs in memory-bound models but does not address cost-bound scenarios. |
RUIE: Retrieval-based Unified Information Extraction using Large Language Model (2025.coling-main)
Copied to clipboard
| Challenge: | Unified information extraction (UIE) aims to extract diverse structured information from unstructured text using a single model or framework. |
| Approach: | They propose a framework that leverages in-context learning for efficient task generalization by combining LLM preferences with a keyword-enhanced reward model. |
| Outcome: | The proposed framework performs better on eight held-out datasets than existing methods and instruction-tuning methods. |

| Challenge: | Existing datasets for Chinese instruction tuning are not well-aligned with Chinese users’ interaction patterns. |
| Approach: | They propose to use Chinese instruction tuning datasets to improve instruction fine-tuning for Chinese users. |
| Outcome: | The proposed dataset shows that Chinese models achieve competitive performance in diverse benchmarks. |
