Earlier RL methods for shortening them apply length penalties uniformly across tokens, which can hurt answer correctness. This paper treats the problem at the token level. It notes that a large share of CoT tokens barely influence the… 2. **[RAG or Learning? Understanding the Limits of LLM Adaptation under Continuous Knowledge Drift in the Real World](https://md.research.elamur.ai/free/en/papers/liu-2026-rag-or-learning-understanding-limits/)** *(2026)* LLMs learn facts at pretraining time, so they fall out of date as the world changes. They may also mix up older and newer states of the same fact, which the authors call continuous knowledge drift. Continual finetuning, knowledge editing and RAG have rarely been tested on realistic, chronologically ordered streams of… ## Co-authors here 7 co-authors with a page, the most papers together first. - [Lang Cao](https://md.research.elamur.ai/free/en/authors/lang-cao/) ×2 - [Dongmei Zhang](https://md.research.elamur.ai/free/en/authors/dongmei-zhang/) - [Haoyu Dong](https://md.research.elamur.ai/free/en/authors/haoyu-dong/) - [Mengyu Zhou](https://md.research.elamur.ai/free/en/authors/mengyu-zhou/) - [Shi Han](https://md.research.elamur.ai/free/en/authors/shi-han/) - [Yang Li](https://md.research.elamur.ai/free/en/authors/yang-li/) - [Yuanyi Ren](https://md.research.elamur.ai/free/en/authors/yuanyi-ren/) ## 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 2026](https://md.research.elamur.ai/free/en/venues/acl/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/) Updated 1 November 2026
