Test-time training methods such as qTTT address this by briefly fine-tuning "fast weights" on the given context. However, they sample positions uniformly, so they… 3. **[HiddenGuard: Fine-Grained Safe Generation with Specialized Representation Router](https://md.research.elamur.ai/free/en/papers/mei-2026-hiddenguard-fine-grained-safe-generation/)** *(2026 · 4 citations)* Safety alignment in LLMs usually works as a yes/no gate: a prompt is either answered or refused. This tends to block harmless requests, such as a "killer slideshow," and to miss subtle or context-dependent harm. The authors propose HiddenGuard, which moderates output token by token instead of refusing whole answers. 4. **[a1: Steep Test-time Scaling Law via Environment Augmented Generation](https://md.research.elamur.ai/free/en/papers/mei-2026-a1-steep-test-time-scaling/)** *(2026 · 2 citations)* LLMs often fail at long multi-step reasoning. They usually generate a whole solution in one pass with no intermediate checks, so an early mistake carries through to the final answer. The authors propose Environment Augmented Generation (EAG), which casts reasoning as a Markov Decision Process. While generating, the… ## Co-authors here 8 co-authors with a page, the most papers together first. - [Baolong Bi](https://md.research.elamur.ai/free/en/authors/baolong-bi/) ×4 - [Shenghua Liu](https://md.research.elamur.ai/free/en/authors/shenghua-liu/) ×4 - [Xueqi Cheng](https://md.research.elamur.ai/free/en/authors/xueqi-cheng/) ×4 - [Yiwei Wang](https://md.research.elamur.ai/free/en/authors/yiwei-wang/) ×4 - [Yuyao Ge](https://md.research.elamur.ai/free/en/authors/yuyao-ge/) ×3 - [Jun Wan](https://md.research.elamur.ai/free/en/authors/jun-wan/) ×2 - [Jiafeng Guo](https://md.research.elamur.ai/free/en/authors/jiafeng-guo/) - [Ruibin Yuan](https://md.research.elamur.ai/free/en/authors/ruibin-yuan/) ## 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/) - [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 17 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/lingrui-mei/cited-by/).
