Its interfaces are dense, its screens are large, and everyday requests often require moving between several programs. The Microsoft authors present UFO, an agent that turns natural-language instructions into executed GUI actions on Windows. It relies on two… 2. **[HAD: HAllucination Detection Language Models Based on a Comprehensive Hallucination Taxonomy](https://md.research.elamur.ai/free/en/papers/xu-2026-had-hallucination-detection-language-models/)** *(2026 · 1 citation)* Large language models often produce fluent text that is wrong or that drifts from the given instruction or input. 3. **[CrossGuard: Safeguarding MLLMs against Joint-Modal Implicit Malicious Attacks](https://md.research.elamur.ai/free/en/papers/zhang-2026-crossguard-safeguarding-mllms-against-joint/)** *(2026)* The paper addresses joint-modal implicit jailbreaks against multimodal LLMs (MLLMs). In these attacks, the image and the text each look harmless, but together they express a harmful request. Current models and guardrails handle single-modality (explicit) attacks fairly well but often miss these combined cases.… 4. **[RST-Guarder: Enhancing Long-Context Robustness for Safeguards via RST Parsing and Probabilistic Inference](https://md.research.elamur.ai/free/en/papers/zhang-2026-rst-guarder-enhancing-long-context/)** *(2026)* Guardrail classifiers such as LlamaGuard and Qwen3Guard decide whether an LLM response is harmful, but they become unreliable as responses get longer. ## Co-authors here 12 of 15 co-authors with a page, the most papers together first. - [Xiaojun Wan](https://md.research.elamur.ai/free/en/authors/xiaojun-wan/) ×2 - [Bo Qiao](https://md.research.elamur.ai/free/en/authors/bo-qiao/) - [Dongmei Zhang](https://md.research.elamur.ai/free/en/authors/dongmei-zhang/) - [Fan Xu](https://md.research.elamur.ai/free/en/authors/fan-xu/) - [Hao Li](https://md.research.elamur.ai/free/en/authors/hao-li/) - [Jinjie Gu](https://md.research.elamur.ai/free/en/authors/jinjie-gu/) - [Li Lin](https://md.research.elamur.ai/free/en/authors/li-lin/) - [Minghua Ma](https://md.research.elamur.ai/free/en/authors/minghua-ma/) - [Qi Zhang](https://md.research.elamur.ai/free/en/authors/qi-zhang/) - [Qingwei Lin](https://md.research.elamur.ai/free/en/authors/qingwei-lin/) - [Saravan Rajmohan](https://md.research.elamur.ai/free/en/authors/saravan-rajmohan/) - [Wei Zhou](https://md.research.elamur.ai/free/en/authors/wei-zhou/) ## 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/) ×3 - [Conference of the North American Chapter of the Association for Computational Linguistics (NAACL)](https://md.research.elamur.ai/free/en/venues/naacl/): [NAACL 2025](https://md.research.elamur.ai/free/en/venues/naacl/2025/) ## Cited by Papers of our library cite their works 30 times (of the 149,439 papers whose bibliographies we read); [12 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xu-zhang/cited-by/).
