Can Model Uncertainty Function as a Proxy for Multiple-Choice Question Item Difficulty? (2025.coling-main)
Copied to clipboard
| Challenge: | Supervised approaches to difficulty estimation have yielded mixed results . generative large models are seen as a weakness when answering questions . |
| Approach: | They exploit generative large models to explore correlations between two different metrics of uncertainty, and the actual student response distribution. |
| Outcome: | The proposed model uncertainty is different in the case of correct vs wrong answers and the student response distribution is different. |
