| Challenge: | Existing approaches to matching use Large Language Models as feature extractors, underutilizing their full modeling capabilities. |
| Approach: | They propose a matching paradigm that integrates two-tower, single-towing, and generative tasks within a unified LLM framework via attention-mask partitioning. |
| Outcome: | The proposed model achieves superior performance and strong practical value in an industrial search engine. |

| Challenge: | Large Multimodal Models (LMMs) are used to capture subtle differences between images but are noisy and coarse summaries. |
| Approach: | They propose a noise-robust approach to image difference capture using large multimodal models . they use LMMs with structured prompts to generate fine-grained change descriptions . |
| Outcome: | The proposed model outperforms streamlined architectures and improves inference efficiency. |
CLIP4IDC: CLIP for Image Difference Captioning (2022.aacl-short)
Copied to clipboard
| Challenge: | Conventional approaches learn an IDC model with a pre-trained and usually frozen visual feature extractor. |
| Approach: | They propose to transfer a CLIP model to the downstream IDC task to address two major issues: (1) a large domain gap exists between the pre-training datasets used for training such a visual feature extractor; (2) the visual feature extraction often does not effectively encode the visual changes between two images. |
| Outcome: | Experiments on three IDC benchmark datasets show the proposed model performs well. |
Extract and Attend: Improving Entity Translation in Neural Machine Translation (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing methods to improve entity translation in Neural machine translation still suffer from inaccurate translation of entities due to the lack of entity training instances. |
| Approach: | They propose an extract-and-tend approach to enhance entity translation in NMT by extracting entities from a dictionary and attending to them with a prefix. |
| Outcome: | Experiments on En-Zh and En-Ru show that the proposed approach improves translation accuracy and translation quality. |
