PPO-style methods, including GRPO and DAPO, clip the importance sampling ratio, and this silently drops gradients from low-probability tokens. The authors split tokens by advantage sign and probability. They argue… 2. **[Entropy Ratio Clipping as a Soft Global Constraint for Stable Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/su-2026-entropy-ratio-clipping-as-soft/)** *(2026 · 1 citation)* LLM post-training with reinforcement learning is usually off-policy, so updates use samples from older policies. 3. **[From Curated Data to Scalable Models: Continual Pre-training of Dense and MoE Large Language Models for Tibetan](https://md.research.elamur.ai/free/en/papers/yang-2026-curated-data-scalable-models-continual/)** *(2026 · 1 citation)* Mainstream LLMs are trained mostly on high-resource languages, so Tibetan remains poorly served despite its millions of speakers and cultural importance. The authors build an end-to-end pipeline to close this gap. 4. **[Good Reasoning Makes Good Demonstrations: Implicit Reasoning Quality Supervision via In-Context Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/mei-2026-good-reasoning-makes-good-demonstrations/)** *(2026)* RLVR rewards every correct answer equally, so a model may also be reinforced for sloppy or lucky reasoning that happens to end in the right result. ## Co-authors here 12 of 18 co-authors with a page, the most papers together first. - [Minxuan Lv](https://md.research.elamur.ai/free/en/authors/minxuan-lv/) ×3 - [Zhenpeng Su](https://md.research.elamur.ai/free/en/authors/zhenpeng-su/) ×3 - [Guorui Zhou](https://md.research.elamur.ai/free/en/authors/guorui-zhou/) ×2 - [Kun Gai](https://md.research.elamur.ai/free/en/authors/kun-gai/) ×2 - [Tiehua Mei](https://md.research.elamur.ai/free/en/authors/tiehua-mei/) ×2 - [Wenping Hu](https://md.research.elamur.ai/free/en/authors/wenping-hu/) ×2 - [Yuntao Li](https://md.research.elamur.ai/free/en/authors/yuntao-li/) ×2 - [Bojian Xiong](https://md.research.elamur.ai/free/en/authors/bojian-xiong/) - [Deqing Yang](https://md.research.elamur.ai/free/en/authors/deqing-yang/) - [Fuzheng Zhang](https://md.research.elamur.ai/free/en/authors/fuzheng-zhang/) - [Jiang Zhou](https://md.research.elamur.ai/free/en/authors/jiang-zhou/) - [Jianxiang Peng](https://md.research.elamur.ai/free/en/authors/jianxiang-peng/) ## 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/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2 - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/) ×2: [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ×2 ## Cited by Papers of our library cite their works 9 times (of the 149,439 papers whose bibliographies we read); [5 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/leiyu-pan/cited-by/).
