TS-Align: A Teacher-Student Collaborative Framework for Scalable Iterative Finetuning of Large Language Models (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Mainstream approaches to aligning large language models heavily rely on human preference data. |
| Approach: | They propose a framework that fine-tunes a policy model using pairwise feedback data automatically mined from its outputs. |
| Outcome: | The proposed framework outperforms the base model with an average win rate of 69.7% across seven conversational or instruction-following datasets. |
CIL: Contrastive Instance Learning Framework for Distantly Supervised Relation Extraction (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods to reduce noise from DS generated training data are not effective for distantly supervised relation extraction (DSRE) |
| Approach: | They propose a multi-instance learning framework to reduce DS noise by dividing training instances into several bags and using them as new data units. |
| Outcome: | The proposed framework improves on NYT10, GDS and KBP with significant improvements over existing methods. |

Hengyi Wang, Haizhou Shi, Shiwei Tan, Weiyi Qin, Wenyuan Wang, Tunyu Zhang, Akshay Nambi, Tanuja Ganu, Hao Wang
| Challenge: | Multimodal Large Language Models have shown significant promise in various applications, but a comprehensive evaluation of their long-context capabilities remains underexplored. |
| Approach: | They propose a benchmark to assess the long-context capabilities of multimodal large language models. |
| Outcome: | The proposed benchmark compared MLLMs with API-based and open-source models in a long-context scenario. |
xDial-Eval: A Multilingual Open-Domain Dialogue Evaluation Benchmark (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Currently, human evaluation is the most reliable way to holistically judge the quality of the dialogue. |
| Approach: | They propose to use English dialogue evaluation metrics to generalize them to other languages. |
| Outcome: | The proposed metrics outperform OpenAI’s ChatGPT in terms of average Pearson correlations over all datasets and languages. |
