Unsupervised Multilingual Dense Retrieval via Generative Pseudo Labeling (2024.findings-eacl)
Copied to clipboard
| Challenge: | Existing sparse retrieval methods often yield inferior performance in multilingual retrieval, requiring a large amount of paired data, which is costly. |
| Approach: | They propose an Unsupervised Multilingual dense Retriever trained without paired data which iteratively improves performance of multilingual retrievers. |
| Outcome: | The proposed framework outperforms supervised baselines on two benchmark datasets and shows that iterative training improves the performance. |
Visually-Enhanced Phrase Understanding (2023.findings-acl)
Copied to clipboard
| Challenge: | Large-scale vision-language pre-training models generate high-quality textual representations, which often outperform models that are purely text-based, such as BERT. |
| Approach: | They propose to utilize both textual and visual encoders of multi-modal pre-trained models to enhance language understanding tasks by generating an image associated with a textual prompt. |
| Outcome: | The proposed method outperforms models that are purely text-based on visual and textual understanding tasks and significantly improves the entity clustering task. |
