Later sub-questions then refer to an earlier result through a pronoun such as "this author" instead of naming the entity. The authors call this failure "lost-in-retrieval." Without the key entity, retrieval for these… 2. **[Bootstrapping Code Translation with Weighted Multilanguage Exploration](https://md.research.elamur.ai/free/en/papers/wu-2026-bootstrapping-code-translation-weighted-multilanguage/)** *(2026)* Translating code between several programming languages with LLMs runs into two problems. Parallel code that comes with executable tests is scarce, and training on many language pairs at once tends to favor the easier directions. BootTrans tackles both with reinforcement learning from verifiable rewards. It starts… 3. **[Skill-Aware Data Selection and Fine-Tuning for Data-Efficient Reasoning Distillation](https://md.research.elamur.ai/free/en/papers/zhang-2026-skill-aware-data-selection-fine/)** *(2026)* Distilling reasoning from large models such as DeepSeek-R1 into smaller LLMs usually relies on large SFT datasets in which every example counts the same. ## Co-authors here 8 co-authors with a page, the most papers together first. - [Chen Shen](https://md.research.elamur.ai/free/en/authors/chen-shen/) - [Huan Zhang](https://md.research.elamur.ai/free/en/authors/huan-zhang/) - [Lechen Zhang](https://md.research.elamur.ai/free/en/authors/lechen-zhang/) - [Lu Wang](https://md.research.elamur.ai/free/en/authors/lu-wang/) - [Wei Cheng](https://md.research.elamur.ai/free/en/authors/wei-cheng/) - [Yiwei Wang](https://md.research.elamur.ai/free/en/authors/yiwei-wang/) - [Yuhan Wu](https://md.research.elamur.ai/free/en/authors/yuhan-wu/) - [Yunxiang Zhang](https://md.research.elamur.ai/free/en/authors/yunxiang-zhang/) ## 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/) ×3: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2, [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ## Cited by Papers of our library cite their works 9 times (of the 149,439 papers whose bibliographies we read); [5 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/wei-hu/cited-by/).
