| Challenge: | Existing evaluation metrics for MCQ generation focus on the n-gram based similarity of the generated MCq to the gold sample and disregard their educational value. |
| Approach: | They propose to use a human survey to measure the MCQ’s answerability given knowledge of the target fact. |
| Outcome: | The proposed methods measure the MCQ’s answerability given knowledge of the target fact. |
GRAM: Fast Fine-tuning of Pre-trained Language Models for Content-based Collaborative Filtering (2022.naacl-main)
Copied to clipboard
| Challenge: | Content-based collaborative filtering (CF) predicts user-item interactions based on both items’ interaction history and item content information. |
| Approach: | They propose to combine item encodings with a multi-modality approach to improve training efficiency by 146x . |
| Outcome: | The proposed model improves training efficiency (up to 146x) on five datasets from two task domains of Knowledge Tracing and News Recommendation. |
