Answer Convergence as a Signal for Early Stopping in Reasoning (2025.emnlp-main)
Copied to clipboard
| Challenge: | a systematic study suggests that chain-of-thought prompting is unnecessary for producing correct answers. |
| Approach: | They propose three inference-time strategies to improve model efficiency by boosting end-of-reasoning signals and early stopping . they propose a method that learns when to stop based on internal activations . |
| Outcome: | The proposed methods reduce token usage with little or no accuracy drop on natural questions . the proposed methods also reduce tokens by over 40% on naturalquestions . |
