IUQ: Interrogative Uncertainty Quantification for Long-Form Large Language Model Generation (2026.acl-long)
Copied to clipboard
| Challenge: | Recent approaches to quantify uncertainty in LLMs produce short or constrained answer sets, but many real-world applications require long-form and free-form text generation. |
| Approach: | They propose a framework that leverages inter-sample consistency and intra-sampled faithfulness to quantify the uncertainty in long-form LLM outputs. |
| Outcome: | The proposed framework provides reliable measures of claim-level uncertainty and the model’s faithfulness over two widely used long-form generation datasets. |
