A small draft model proposes tokens, and the full model checks them in parallel. The authors find that this benefit shrinks for models with big vocabularies, such as Llama-3-8B (128k tokens). They re-implemented EAGLE-2 in native C and CUDA to strip away Python and… 2. **[CuMA: Aligning LLMs with Sparse Cultural Values via Demographic-Aware Mixture of Adapters](https://md.research.elamur.ai/free/en/papers/sun-2026-cuma-aligning-llms-sparse-cultural/)** *(2026 · 1 citation)* Standard LLM alignment fits one shared set of weights to pooled human feedback. That works when a single correct answer exists, but it breaks down on culturally contested questions. The authors argue that the value distributions of different demographic groups form well-separated clusters, which they call Cultural… ## Co-authors here 10 co-authors with a page, the most papers together first. - [Hao Zhou](https://md.research.elamur.ai/free/en/authors/hao-zhou/) - [Jianyong Wang](https://md.research.elamur.ai/free/en/authors/jianyong-wang/) - [Jie Zhou](https://md.research.elamur.ai/free/en/authors/jie-zhou/) - [Weilin Zhao](https://md.research.elamur.ai/free/en/authors/weilin-zhao/) - [Xu Han](https://md.research.elamur.ai/free/en/authors/xu-han/) - [Yu Li](https://md.research.elamur.ai/free/en/authors/yu-li/) - [Yudi Zhang](https://md.research.elamur.ai/free/en/authors/yudi-zhang/) - [Yuheng Jia](https://md.research.elamur.ai/free/en/authors/yuheng-jia/) - [Yuxiang Huang](https://md.research.elamur.ai/free/en/authors/yuxiang-huang/) - [Yuxuan Li](https://md.research.elamur.ai/free/en/authors/yuxuan-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/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/), [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ## Cited by Papers of our library cite their works 15 times (of the 149,439 papers whose bibliographies we read); [4 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/ao-sun/cited-by/).
