Complex Numerical Reasoning with Numerical Semantic Pre-training Framework (2025.emnlp-main)
Copied to clipboard
| Challenge: | Numerical knowledge graphs (NKGs) are not limited to discrete entity-relation knowledge. |
| Approach: | They propose to combine numerical values and entities to solve multi-hop complex reasoning over incomplete knowledge graphs. |
| Outcome: | The proposed approach handles up to 102 types of complex numerical reasoning queries on three public datasets. |
How Many Demonstrations Do You Need for In-context Learning? (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Large language models (LLMs) are capable of complex reasoning when given a few input-output demos. |
| Approach: | They use fewer input-output demos for each test query to study ICL . they do not observe significant degradation when using only one randomly chosen demo . |
| Outcome: | The proposed model outperforms multi-demo models on the tasks in 2022. |
TheraAgent: Self-Improving Therapeutic Agent for Precise and Comprehensive Treatment Planning (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing large language models rely on one-shot output without explicit verification, resulting in rough, incomplete, and potentially unsafe treatment plans. |
| Approach: | They propose an agentic framework that replaces one-shot generation with an iterative generate-judge-refine pipeline. |
| Outcome: | The proposed framework achieves state-of-the-art results on HealthBench, leading in Accuracy and Completeness. |
