Is That Your Final Answer? Test-Time Scaling Improves Selective Question Answering (2025.acl-short)
Copied to clipboard
| Challenge: | Existing evaluations of test-time scaling assume that a reasoning system should always give an answer to any question provided. |
| Approach: | They propose to increase compute budget at inference time to increase confidence in correct responses by considering settings with non-zero levels of response risk. |
| Outcome: | The proposed model can answer more questions correctly and have higher confidence in correct responses. |
