Incentivizing Strong Reasoning from Weak Supervision (2026.eacl-long)
Copied to clipboard
| Challenge: | Large language models (LLMs) have demonstrated impressive performance on reasoning-intensive tasks, but enhancing their reasoning abilities typically relies on expensive high-quality demonstrations and reinforcement learning. |
| Approach: | They propose to incentivize reasoning abilities of large language models without expensive demonstrations and reinforcement learning. |
| Outcome: | The proposed model can recover 94% of the gains of expensive RL at a fraction of the cost. |

| Challenge: | Existing approaches to tool learning rely on hand-crafted prompts and natural language reasoning, making multi-step planning difficult and lacking precise error diagnosis and reflection mechanisms. |
| Approach: | They propose a framework that reformulates tool learning as a code generation task. |
| Outcome: | The proposed framework achieves superior performance in task completion accuracy and execution reliability compared to existing approaches. |

| Challenge: | Existing methods express reliability by confidence level, but lack objective guidance . Existing approaches express reliability but lack guidance on when to trust LLMs . |
| Approach: | They propose a reward-based approach to align confidence with quality to ensure reliability . they propose 'conqORD' to help model to verbalize greater confidence for higher quality responses . |
| Outcome: | Experiments show that CONQORD significantly improves confidence and response accuracy . the proposed approach can be used to determine reliability of large language models . |
Language Adaptation of Large Language Models: An Empirical Study on LLaMA2 (2025.coling-main)
Copied to clipboard
| Challenge: | Popularity of Large Language Models (LLMs) has seen a skyrocketing increase in recent years. |
| Approach: | They present a systematic review of the language adaptation process for Large Language Models including vocabulary expansion, continued pre-training, and instruction fine-tuning. |
| Outcome: | The proposed model is based on empirical studies conducted on LLaMA2 and discussions on various settings affecting the model's capabilities. |
