N-gram metrics such as BLEU, Rouge and METEOR are cheap but align poorly with human opinion on open-ended outputs. Using a single LLM as a judge narrows this gap but does not yet reach human-level quality. ChatEval responds by turning evaluation… 3. **[RQ-RAG: Learning to Refine Queries for Retrieval Augmented Generation](https://md.research.elamur.ai/free/en/papers/chan-2024-rq-rag-learning-refine-queries/)** *(2024 · 90 citations)* Retrieval-augmented LLMs usually send the user's raw input straight to the search step. This works poorly in three cases. Simple inputs like greetings need no retrieval at all. Multi-step questions need splitting into parts. Vague questions have several valid readings. RQ-RAG addresses this by teaching a 7B Llama2… ## Co-authors here 11 co-authors with a page, the most papers together first. - [Chi-Min Chan](https://md.research.elamur.ai/free/en/authors/chi-min-chan/) ×2 - [Jie Fu](https://md.research.elamur.ai/free/en/authors/jie-fu/) ×2 - [Chunpu Xu](https://md.research.elamur.ai/free/en/authors/chunpu-xu/) - [Hongyin Luo](https://md.research.elamur.ai/free/en/authors/hongyin-luo/) - [Ruibin Yuan](https://md.research.elamur.ai/free/en/authors/ruibin-yuan/) - [Shanghang Zhang](https://md.research.elamur.ai/free/en/authors/shanghang-zhang/) - [Tao Li](https://md.research.elamur.ai/free/en/authors/tao-li/) - [Weize Chen](https://md.research.elamur.ai/free/en/authors/weize-chen/) - [Yike Guo](https://md.research.elamur.ai/free/en/authors/yike-guo/) - [Yusheng Su](https://md.research.elamur.ai/free/en/authors/yusheng-su/) - [Zhiyuan Liu](https://md.research.elamur.ai/free/en/authors/zhiyuan-liu/) ## 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 2018](https://md.research.elamur.ai/free/en/venues/acl/2018/) ## Cited by Papers of our library cite their works 476 times (of the 149,439 papers whose bibliographies we read); [114 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/wei-xue/cited-by/).
