Are Generative Models Underconfident? Better Quality Estimation with Boosted Model Probability (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing studies have shown that text-generation models can be overconfident when there are multiple correct options. |
| Approach: | They propose a QE approach called BoostedProb which boosts the model’s confidence in cases where there are multiple viable output options. |
| Outcome: | The proposed approach achieves on average +0.194 improvement in Pearson correlation to ground-truth quality and outperforms more costly approaches like supervised or ensemble-based QE in certain settings. |
