Most existing detectors look only at output confidence, such as logit entropy, or rely on external verifiers. VIB-Probe looks inside the model instead. During decoding, it collects the raw per-head attention outputs from every… 3. **[Peering Behind the Shield: Guardrail Identification in Large Language Models](https://md.research.elamur.ai/free/en/papers/yang-2026-peering-behind-shield-guardrail-identification/)** *(2026 · 1 citation)* Conversational AI agents often place safety guardrails before or after their core LLM. Knowing which guardrail is in use lets an attacker treat it as a white-box target. Existing LLM fingerprinting methods transfer poorly to this task for four reasons: guardrails give near-binary verdicts, agents allow only black-box… 4. **[Mitigating Hallucinations in VLMs: Enhancing Visual Attention via Head-Wise Perturbation](https://md.research.elamur.ai/free/en/papers/wang-2026-mitigating-hallucinations-vlms-enhancing-visual/)** *(2026)* Vision-language models often hallucinate because they lean on the language priors of their LLM backbone instead of the image. 5. **[Mitigating Position Bias in Transformers via Layer-Specific Positional Embedding Scaling](https://md.research.elamur.ai/free/en/papers/wang-2026-mitigating-position-bias-transformers-layer/)** *(2026)* Long-context LLMs that use RoPE tend to concentrate attention on the start and end of the input. As a result, they underuse content in the middle, a problem known as "lost-in-the-middle." Earlier fixes such as Attention Buckets, MoICE and Ms-PoE mix several RoPE bases or scales. However, they need repeated forward… ## All works 6 works of theirs in our library, the most cited first; 5 with a page here, the others link their original until we summarise them. 1. **[Searching for Best Practices in Retrieval-Augmented Generation](https://md.research.elamur.ai/free/en/papers/wang-2024-searching-best-practices-retrieval-augmented/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**Xiaohua Wang, Zhenghua Wang, Xuan Gao, et al.*2024 · 150 citations* 2. **[VIB-Probe: Detecting and Mitigating Hallucinations in Vision-Language Models via Variational Information Bottleneck](https://md.research.elamur.ai/free/en/papers/zhang-2026-vib-probe-detecting-mitigating-hallucinations/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Feiran Zhang, Yixin Wu, Zhenghua Wang, et al.*2026 · 3 citations* 3. **[Peering Behind the Shield: Guardrail Identification in Large Language Models](https://md.research.elamur.ai/free/en/papers/yang-2026-peering-behind-shield-guardrail-identification/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Ziqing Yang, Yixin Wu, Rui Wen, et al.*2026 · 1 citation* 4. **[Mitigating Hallucinations in VLMs: Enhancing Visual Attention via Head-Wise Perturbation](https://md.research.elamur.ai/free/en/papers/wang-2026-mitigating-hallucinations-vlms-enhancing-visual/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Zhenghua Wang, Yixin Wu, Feiran Zhang, et al.*2026* 5. **[Mitigating Position Bias in Transformers via Layer-Specific Positional Embedding Scaling](https://md.research.elamur.ai/free/en/papers/wang-2026-mitigating-position-bias-transformers-layer/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Zhenghua Wang, Yiran Ding, Changze Lv, et al.*2026* 6. **[InferPilot: Autonomous Inference Attacks Against ML Services With LLM-Based Agents ↗](https://aclanthology.org/2026.findings-acl.572/) Findings of the Association for Computational Linguistics: ACL 2026 · no summary yet**Yixin Wu et al.*2026* ## Co-authors here 12 of 17 co-authors with a page, the most papers together first. - [Changze Lv](https://md.research.elamur.ai/free/en/authors/changze-lv/) ×4 - [Zhenghua Wang](https://md.research.elamur.ai/free/en/authors/zhenghua-wang/) ×4 - [Feiran Zhang](https://md.research.elamur.ai/free/en/authors/feiran-zhang/) ×3 - [Qi Qian](https://md.research.elamur.ai/free/en/authors/qi-qian/) ×3 - [Xiaoqing Zheng](https://md.research.elamur.ai/free/en/authors/xiaoqing-zheng/) ×3 - [Xuanjing Huang](https://md.research.elamur.ai/free/en/authors/xuanjing-huang/) ×3 - [Shizheng Li](https://md.research.elamur.ai/free/en/authors/shizheng-li/) ×2 - [Tianyuan Shi](https://md.research.elamur.ai/free/en/authors/tianyuan-shi/) ×2 - [Xiaohua Wang](https://md.research.elamur.ai/free/en/authors/xiaohua-wang/) ×2 - [Zhibo Xu](https://md.research.elamur.ai/free/en/authors/zhibo-xu/) ×2 - [Michael Backes](https://md.research.elamur.ai/free/en/authors/michael-backes/) - [Muling Wu](https://md.research.elamur.ai/free/en/authors/muling-wu/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/) ×3: [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ×3 - [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/) - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2024](https://md.research.elamur.ai/free/en/venues/emnlp/2024/) - Findings of the Association for Computational Linguistics: ACL 2026 ## Cited by Papers of our library cite their works 41 times (of the 149,439 papers whose bibliographies we read); [6 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yixin-wu/cited-by/).
