They have two weaknesses. They spend reasoning effort on every input, including easy ones. They also pick among sampled reasoning chains by voting, which cannot separate sound chains from ones that only look convincing. The… 2. **[Why Supervised Fine-Tuning Fails to Learn: A Systematic Study of Incomplete Learning in Large Language Models](https://md.research.elamur.ai/free/en/papers/xue-2026-why-supervised-fine-tuning-fails/)** *(2026 · 6 citations)* Supervised fine-tuning (SFT) is usually treated as a reliable way to specialize LLMs. The authors show, however, that converged models still get part of their own training set wrong. They call this the Incomplete Learning Phenomenon (ILP), distinguish it from catastrophic forgetting and machine unlearning, and… 3. **[Mitigating Cultural Bias in LLMs via Multi-Agent Cultural Debate](https://md.research.elamur.ai/free/en/papers/tan-2026-mitigating-cultural-bias-llms-multi/)** *(2026)* The paper asks whether prompting LLMs in Chinese instead of English reduces their Western-leaning cultural defaults, and how such bias can be reduced without retraining. ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Chao Xue](https://md.research.elamur.ai/free/en/authors/chao-xue/) ×2 - [Chenyao Lu](https://md.research.elamur.ai/free/en/authors/chenyao-lu/) ×2 - [Di Liang](https://md.research.elamur.ai/free/en/authors/di-liang/) ×2 - [Haibo Shi](https://md.research.elamur.ai/free/en/authors/haibo-shi/) ×2 - [Mengqiao Liu](https://md.research.elamur.ai/free/en/authors/mengqiao-liu/) ×2 - [Peiyang Liu](https://md.research.elamur.ai/free/en/authors/peiyang-liu/) ×2 - [Shuang Liang](https://md.research.elamur.ai/free/en/authors/shuang-liang/) ×2 - [Xianjie Wu](https://md.research.elamur.ai/free/en/authors/xianjie-wu/) ×2 - [Xingsheng Han](https://md.research.elamur.ai/free/en/authors/xingsheng-han/) ×2 - [Yao Wang](https://md.research.elamur.ai/free/en/authors/yao-wang/) ×2 - [Yu Lu](https://md.research.elamur.ai/free/en/authors/yu-lu/) ×2 - [Shuoyang Ding](https://md.research.elamur.ai/free/en/authors/shuoyang-ding/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [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 - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ## Cited by Papers of our library cite their works 14 times (of the 149,439 papers whose bibliographies we read); [6 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/lei-jiang/cited-by/).
