Enterprise support users, however, tend to arrive with a whole episode of connected needs, and the documents relevant to that episode often sit far apart in embedding space. The authors frame this as a session problem and propose two… 3. **[The Geometry of Refusal: Linear Instability in Safety-Aligned LLMs](https://md.research.elamur.ai/free/en/papers/ratnakar-2026-geometry-refusal-linear-instability-safety/)** *(2026)* The paper asks whether refusal in safety-aligned LLMs reflects deep semantic judgment or a shallow linear feature that can be manipulated. ## 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/) - [Workshop on Towards Knowledgeable Foundation Models](https://md.research.elamur.ai/free/en/venues/knowfm/): [Workshop on Towards Knowledgeable Foundation Models 2026](https://md.research.elamur.ai/free/en/venues/knowfm/2026/) - [Workshop on Trustworthy NLP](https://md.research.elamur.ai/free/en/venues/trustnlp/): [Workshop on Trustworthy NLP 2026](https://md.research.elamur.ai/free/en/venues/trustnlp/2026/) Updated 1 November 2026
