Neural News Recommendation with Collaborative News Encoding and Structural User Encoding (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing news recommendation models encode news title and content separately without leveraging the structural correlation of user browsing histories to reflect user interests explicitly. |
| Approach: | They propose a news recommendation framework consisting of collaborative news encoding and structural user encode to enhance news and user representation learning. |
| Outcome: | The proposed framework improves the performance of news recommendation on the MIND dataset. |
DM-BLI: Dynamic Multiple Subspaces Alignment for Unsupervised Bilingual Lexicon Induction (2024.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to unsupervised bilingual lexicon induction (BLI) fail on distant or low-resource language pairs, achieving less than half the performance observed in rich-resourced languages. |
| Approach: | They propose a framework for unsupervised bilingual lexicon induction that uses multiple subspace alignments instead of a single mapping. |
| Outcome: | Experiments on 12 language pairs show that the proposed framework improves language alignment by utilizing multiple subspace alignments instead of a single mapping. |

| Challenge: | Unsupervised clustering aims at discovering the semantic categories of data according to some distance measured in the representation space, but different categories overlap with each other at the beginning of the learning process. |
| Approach: | They propose a framework to leverage contrastive learning to promote better separation between different categories by optimizing a clustering objective defined in the representation space. |
| Outcome: | The proposed framework improves state-of-the-art accuracy and normalized mutual information on short text clustering and combines top-down and bottom-up instance discrimination to achieve better distances. |
