This hurts creative writing, best-of-N selection, synthetic data creation and test-time scaling for reasoning. Raising the sampling temperature adds variety but lowers quality, and re-prompting with earlier answers can drift away from… 2. **[GIFT: Guided Fine-Tuning and Transfer for Enhancing Instruction-Tuned Language Models](https://md.research.elamur.ai/free/en/papers/ruan-2026-gift-guided-fine-tuning-transfer/)** *(2026)* Adapting instruction-tuned LLMs to a specific domain is risky: fine-tuning them directly can disturb the balance of skills built during post-training. ## Co-authors here 11 co-authors with a page, the most papers together first. - [Guanhua Chen](https://md.research.elamur.ai/free/en/authors/guanhua-chen/) ×2 - [Peng Li](https://md.research.elamur.ai/free/en/authors/peng-li/) ×2 - [Yang Liu](https://md.research.elamur.ai/free/en/authors/yang-liu/) ×2 - [Yun Chen](https://md.research.elamur.ai/free/en/authors/yun-chen/) ×2 - [Jianjie Zheng](https://md.research.elamur.ai/free/en/authors/jianjie-zheng/) - [Jinsong Su](https://md.research.elamur.ai/free/en/authors/jinsong-su/) - [Longyue Wang](https://md.research.elamur.ai/free/en/authors/longyue-wang/) - [Weihua Luo](https://md.research.elamur.ai/free/en/authors/weihua-luo/) - [Yefeng Liu](https://md.research.elamur.ai/free/en/authors/yefeng-liu/) - [Yichao Du](https://md.research.elamur.ai/free/en/authors/yichao-du/) - [Yixia Li](https://md.research.elamur.ai/free/en/authors/yixia-li/) ## 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/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [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/) ## Cited by Papers of our library cite their works 5 times (of the 149,439 papers whose bibliographies we read); [2 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/zhiwen-ruan/cited-by/).
