| Challenge: | Uncertainty quantification (UQ) is a promising approach for detecting hallucinations and low-quality outputs of Large Language Models (LLMs). |
| Approach: | They propose to learn conditional dependency between autoregressive LLM generation steps from attention-based features and a two-staged training procedure to incorporate recurrent features. |
| Outcome: | The proposed method is highly effective for selective generation, achieving substantial improvements over rivaling unsupervised and supervised approaches. |
