Confidence-Aware Reasoning: Optimizing Self-Guided Thinking Trajectories in Large Reasoning Models (2025.emnlp-industry)
Copied to clipboard
| Challenge: | Chain-of-thought enables large reasoning models to reason through multi-step problems but often leads to unnecessarily long or redundant reasoning traces, a phenomenon known as overthinking. |
| Approach: | They propose an inference-time framework that selectively prunes low-utility reasoning blocks and halts early when sufficient confidence has been achieved. |
| Outcome: | The proposed framework improves answer accuracy by up to +13.3% while reducing average reasoning length by 40%–50%. |
