Its PPO stage, though, is unstable, sensitive to hyperparameters and costly to debug, and few open implementations existed. This report from the Fudan NLP Group and ByteDance breaks the RLHF pipeline into its stages: SFT, reward model training, and PPO… 4. **[Is LLM a Reliable Reviewer? A Comprehensive Evaluation of LLM on Automatic Paper Reviewing Tasks](https://md.research.elamur.ai/free/en/papers/zhou-2024-is-llm-reliable-reviewer-comprehensive/)** *(2024 · 73 citations)* The paper asks whether large language models can be trusted as automatic peer reviewers, a question earlier review datasets did not answer well because they did not verify that generated reviews were correct. ## Co-authors here 10 co-authors with a page, the most papers together first. - [Kai Yu](https://md.research.elamur.ai/free/en/authors/kai-yu/) ×3 - [Kaige Xie](https://md.research.elamur.ai/free/en/authors/kaige-xie/) - [Qin Liu](https://md.research.elamur.ai/free/en/authors/qin-liu/) - [Rui Zheng](https://md.research.elamur.ai/free/en/authors/rui-zheng/) - [Ruisheng Cao](https://md.research.elamur.ai/free/en/authors/ruisheng-cao/) - [Senjie Jin](https://md.research.elamur.ai/free/en/authors/senjie-jin/) - [Wei Shen](https://md.research.elamur.ai/free/en/authors/wei-shen/) - [Yan Liu](https://md.research.elamur.ai/free/en/authors/yan-liu/) - [Yanbin Zhao](https://md.research.elamur.ai/free/en/authors/yanbin-zhao/) - [Zhi Chen](https://md.research.elamur.ai/free/en/authors/zhi-chen/) ## 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 2021](https://md.research.elamur.ai/free/en/venues/acl/2021/) - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2018](https://md.research.elamur.ai/free/en/venues/emnlp/2018/) - [Language Resources and Evaluation Conference (LREC)](https://md.research.elamur.ai/free/en/venues/lrec/): [LREC 2024](https://md.research.elamur.ai/free/en/venues/lrec/2024/) ## Cited by Papers of our library cite their works 268 times (of the 141,840 papers whose bibliographies we read); [25 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/lu-chen/cited-by/).
