In real social interaction, however, people's beliefs, feelings and goals change over time. The authors address this gap with DynToM, a benchmark that checks whether models can follow how a character's mental state develops across a… 2. **[KNN-SSD: Enabling Dynamic Self-Speculative Decoding via Nearest Neighbor Layer Set Optimization](https://md.research.elamur.ai/free/en/papers/song-2026-knn-ssd-enabling-dynamic-self/)** *(2026 · 5 citations)* Self-speculative decoding (Self-SD) speeds up LLM inference by skipping some of the model's own layers to produce draft tokens, which the full model then verifies. 3. **[TInR: Exploring Tool-Internalized Reasoning in Large Language Models](https://md.research.elamur.ai/free/en/papers/xu-2026-tinr-exploring-tool-internalized-reasoning/)** *(2026 · 1 citation)* The paper addresses a weakness of Tool-Integrated Reasoning (TIR). In TIR, LLMs call external tools while reasoning but need the tools' documentation placed in the prompt. The authors argue this causes three problems: models struggle to master heterogeneous documentation, context windows limit how many tools fit, and… ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Wenjie Li](https://md.research.elamur.ai/free/en/authors/wenjie-li/) ×3 - [Chak Tou Leong](https://md.research.elamur.ai/free/en/authors/chak-tou-leong/) - [Chunpu Xu](https://md.research.elamur.ai/free/en/authors/chunpu-xu/) - [Fan Liu](https://md.research.elamur.ai/free/en/authors/fan-liu/) - [Heming Xia](https://md.research.elamur.ai/free/en/authors/heming-xia/) - [Hongru Wang](https://md.research.elamur.ai/free/en/authors/hongru-wang/) - [Jun Zhang](https://md.research.elamur.ai/free/en/authors/jun-zhang/) - [Min Yang](https://md.research.elamur.ai/free/en/authors/min-yang/) - [Mingbo Song](https://md.research.elamur.ai/free/en/authors/mingbo-song/) - [Pengfei Liu](https://md.research.elamur.ai/free/en/authors/pengfei-liu/) - [Sujian Li](https://md.research.elamur.ai/free/en/authors/sujian-li/) - [Yang Xiao](https://md.research.elamur.ai/free/en/authors/yang-xiao/) ## 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/) ## Cited by Papers of our library cite their works 11 times (of the 149,439 papers whose bibliographies we read); [4 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/qiancheng-xu/cited-by/).
