Such passages lower answer quality and add inference cost. MAIN-RAG is a post-retrieval filtering framework that needs no training or fine-tuning and runs on top of a standard retriever. It uses three LLM agents: 3. **[FaithLM: Towards Faithful Explanations for Large Language Models](https://md.research.elamur.ai/free/en/papers/chuang-2026-faithlm-faithful-explanations-large-language/)** *(2026 · 9 citations)* LLMs often explain their answers in natural language, but these explanations frequently do not reflect what actually drove the prediction. Classic fidelity tests, which delete important tokens, also fit poorly with free-text rationales whose content is semantic rather than token-level. 4. **[AutoL2S: Auto Long-Short Reasoning for Efficient Large Language Models](https://md.research.elamur.ai/free/en/papers/luo-2026-autol2s-auto-long-short-reasoning/)** *(2026 · 7 citations)* Distilling reasoning from strong teacher LLMs into non-reasoning students often causes "overthinking": the students produce very long chain-of-thought (CoT) traces even for easy questions, which raises decoding time and cost. ## Co-authors here 12 of 19 co-authors with a page, the most papers together first. - [Shaochen Zhong](https://md.research.elamur.ai/free/en/authors/shaochen-zhong/) ×3 - [Xia Hu](https://md.research.elamur.ai/free/en/authors/xia-hu/) ×3 - [Yu-Neng Chuang](https://md.research.elamur.ai/free/en/authors/yu-neng-chuang/) ×3 - [Andrew Wen](https://md.research.elamur.ai/free/en/authors/andrew-wen/) ×2 - [Chia-Yuan Chang](https://md.research.elamur.ai/free/en/authors/chia-yuan-chang/) ×2 - [Hongyi Liu](https://md.research.elamur.ai/free/en/authors/hongyi-liu/) ×2 - [Jiayi Yuan](https://md.research.elamur.ai/free/en/authors/jiayi-yuan/) ×2 - [Na Zou](https://md.research.elamur.ai/free/en/authors/na-zou/) ×2 - [Vladimir Braverman](https://md.research.elamur.ai/free/en/authors/vladimir-braverman/) ×2 - [Yang Sui](https://md.research.elamur.ai/free/en/authors/yang-sui/) ×2 - [Fan Yang](https://md.research.elamur.ai/free/en/authors/fan-yang/) - [Hanjie Chen](https://md.research.elamur.ai/free/en/authors/hanjie-chen/) ## 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 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) - [Conference of the European Chapter of the Association for Computational Linguistics (EACL)](https://md.research.elamur.ai/free/en/venues/eacl/): [EACL 2026](https://md.research.elamur.ai/free/en/venues/eacl/2026/) - [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 194 times (of the 149,439 papers whose bibliographies we read); [57 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/guanchu-wang/cited-by/).
