Existing jailbreaks are either expensive, relying on iterative optimization as in GCG or AutoDAN, or rigid hand-written templates. Wei et al. show that in-context learning alone can push a model's safety behaviour in either direction. 2. **[POSITION BIAS MITIGATES POSITION BIAS: Mitigate Position Bias Through Inter-Position Knowledge Distillation](https://md.research.elamur.ai/free/en/papers/wang-2025-position-bias-mitigates-position-bias/)** *(2025 · 13 citations)* Long-context LLMs use information unevenly: content near the beginning or end of the input is used reliably, while material placed in the middle is often missed. 3. **[HS-STaR: Hierarchical Sampling for Self-Taught Reasoners via Difficulty Estimation and Budget Reallocation](https://md.research.elamur.ai/free/en/papers/xiong-2025-hs-star-hierarchical-sampling-self/)** *(2025 · 9 citations)* Self-taught reasoners (STaRs) improve LLM mathematical reasoning by training on their own sampled solutions. 4. **[R³: End-to-End Reasoning-based Planning for Multi-step Retrosynthesis via Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/wang-2026-r-3-end-end-reasoning/)** *(2026)* Multi-step retrosynthesis means breaking a target molecule down, step by step, into purchasable building blocks. ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Feng Xiong](https://md.research.elamur.ai/free/en/authors/feng-xiong/) ×2 - [Xiangxiang Chu](https://md.research.elamur.ai/free/en/authors/xiangxiang-chu/) ×2 - [Yong Wang](https://md.research.elamur.ai/free/en/authors/yong-wang/) ×2 - [Ang Li](https://md.research.elamur.ai/free/en/authors/ang-li/) - [Daniel Dajun Zeng](https://md.research.elamur.ai/free/en/authors/daniel-dajun-zeng/) - [Hao Zhou](https://md.research.elamur.ai/free/en/authors/hao-zhou/) - [Jiangtao Feng](https://md.research.elamur.ai/free/en/authors/jiangtao-feng/) - [Lei Bai](https://md.research.elamur.ai/free/en/authors/lei-bai/) - [Lijun Wu](https://md.research.elamur.ai/free/en/authors/lijun-wu/) - [Linjing Li](https://md.research.elamur.ai/free/en/authors/linjing-li/) - [Qizhi Pei](https://md.research.elamur.ai/free/en/authors/qizhi-pei/) - [Runxi Cheng](https://md.research.elamur.ai/free/en/authors/runxi-cheng/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/) ×2: [EMNLP 2025](https://md.research.elamur.ai/free/en/venues/emnlp/2025/) ×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 151 times (of the 149,439 papers whose bibliographies we read); [35 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yifei-wang/cited-by/).
