This pushes a model toward an "average user" and ignores people whose tastes conflict, such as those who want useful but short answers. The authors propose Directional Preference Alignment (DPA) to address this. ## Co-authors here 6 co-authors with a page, the most papers together first. - [Haoxiang Wang](https://md.research.elamur.ai/free/en/authors/haoxiang-wang/) ×2 - [Tong Zhang](https://md.research.elamur.ai/free/en/authors/tong-zhang/) ×2 - [Wei Xiong](https://md.research.elamur.ai/free/en/authors/wei-xiong/) ×2 - [Rui Yang](https://md.research.elamur.ai/free/en/authors/rui-yang/) - [Shizhe Diao](https://md.research.elamur.ai/free/en/authors/shizhe-diao/) - [Yong Lin](https://md.research.elamur.ai/free/en/authors/yong-lin/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2024](https://md.research.elamur.ai/free/en/venues/acl/2024/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2024](https://md.research.elamur.ai/free/en/venues/findings/2024/) ## Cited by Papers of our library cite their works 184 times (of the 141,840 papers whose bibliographies we read); [8 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/han-zhao/cited-by/).
