Most build datasets tool-first: they gather tools and then synthesize queries for them. Such tools often do not depend on one another, and answers cannot be checked reliably, so evaluation falls back on model-based judging, which carries bias. ToolHop… 2. **[Feedback-Driven Tool-Use Improvements in Large Language Models via Automated Build Environments](https://md.research.elamur.ai/free/en/papers/ye-2026-feedback-driven-tool-use-improvements/)** *(2026 · 6 citations)* Training LLMs to call tools with reinforcement learning is difficult for two reasons. Online APIs make training environments unstable and costly to maintain, and judging trajectories usually requires a strong LLM as evaluator, which brings bias. The authors propose FTRL, which removes both problems. An automated… 3. **[Recitation over Reasoning: How Cutting-Edge Language Models Can Fail on Elementary School-Level Reasoning Problems?](https://md.research.elamur.ai/free/en/papers/yan-2025-recitation-over-reasoning-how-cutting/)** *(2025 · 5 citations)* The paper asks whether frontier LLMs actually reason through simple problems or mostly reproduce memorized solution templates. 4. **[Beyond the Context Window: Scaling Agentic RL via End-to-end Optimized Context Compression](https://md.research.elamur.ai/free/en/papers/lu-2026-beyond-context-window-scaling-agentic/)** *(2026)* Training LLM agents with reinforcement learning on long multi-turn tool-use tasks is limited by context growth. ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Jiecao Chen](https://md.research.elamur.ai/free/en/authors/jiecao-chen/) ×3 - [Yufei Xu](https://md.research.elamur.ai/free/en/authors/yufei-xu/) ×3 - [Zhengyin Du](https://md.research.elamur.ai/free/en/authors/zhengyin-du/) ×3 - [Junjie Ye](https://md.research.elamur.ai/free/en/authors/junjie-ye/) ×2 - [Qi Zhang](https://md.research.elamur.ai/free/en/authors/qi-zhang/) ×2 - [Tao Gui](https://md.research.elamur.ai/free/en/authors/tao-gui/) ×2 - [Zhiheng Xi](https://md.research.elamur.ai/free/en/authors/zhiheng-xi/) ×2 - [Kang Liu](https://md.research.elamur.ai/free/en/authors/kang-liu/) - [Siyu Yuan](https://md.research.elamur.ai/free/en/authors/siyu-yuan/) - [Weiwei Sun](https://md.research.elamur.ai/free/en/authors/weiwei-sun/) - [Xiaoran Fan](https://md.research.elamur.ai/free/en/authors/xiaoran-fan/) - [Xuanjing Huang](https://md.research.elamur.ai/free/en/authors/xuanjing-huang/) ## 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/), [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/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/) - [International Joint Conference on Natural Language Processing (IJCNLP)](https://md.research.elamur.ai/free/en/venues/ijcnlp/): [IJCNLP 2025](https://md.research.elamur.ai/free/en/venues/ijcnlp/2025/) ## Cited by Papers of our library cite their works 21 times (of the 149,439 papers whose bibliographies we read); [8 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xuesong-yao/cited-by/).
