Most existing PRMs output a score directly, which limits how well they learn and gives no explanation for a judgment. Step-level labeled data is also scarce. R-PRM addresses this by having the reward model write an analysis of each step… 2. **[Mending the Holes: Mitigating Reward Hacking in Reinforcement Learning for Multilingual Translation](https://md.research.elamur.ai/free/en/papers/liu-2026-mending-holes-mitigating-reward-hacking/)** *(2026 · 2 citations)* LLM translation quality drops sharply for low-resource languages, and the usual post-training fixes require parallel or preference data that these languages often lack. ## Co-authors here 6 co-authors with a page, the most papers together first. - [Jiajun Chen](https://md.research.elamur.ai/free/en/authors/jiajun-chen/) - [Lei Li](https://md.research.elamur.ai/free/en/authors/lei-li/) - [Shuaijie She](https://md.research.elamur.ai/free/en/authors/shuaijie-she/) - [Shujian Huang](https://md.research.elamur.ai/free/en/authors/shujian-huang/) - [Siqi Ouyang](https://md.research.elamur.ai/free/en/authors/siqi-ouyang/) - [Xin Huang](https://md.research.elamur.ai/free/en/authors/xin-huang/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2025](https://md.research.elamur.ai/free/en/venues/emnlp/2025/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ## Cited by Papers of our library cite their works 437 times (of the 149,439 papers whose bibliographies we read); [176 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yifeng-liu/cited-by/).
