In these tasks an agent explores a room over many turns and must work with long sequences of alternating images and text. The authors present Embodied-Reasoner, a vision-language agent that combines visual search… 2. **[Capability Decomposition for Unified Information Extraction via Hierarchical Mixture-of-Experts](https://md.research.elamur.ai/free/en/papers/zhou-2026-capability-decomposition-unified-information-extraction/)** *(2026)* The paper addresses Unified Information Extraction (UIE): handling heterogeneous IE tasks (NER, RE, EE, ABSA) with one model. 3. **[Exploring Layer Activation Dynamic of CoT via Knowledge Probe](https://md.research.elamur.ai/free/en/papers/zhang-2026-exploring-layer-activation-dynamic-cot/)** *(2026)* The paper investigates how instruction-tuned LLMs internally carry out chain-of-thought (CoT) reasoning. Earlier interpretability research mostly studied single-step factual recall, so it remained unclear how knowledge is called up and passed between tokens across successive reasoning steps. The authors require… 4. **[Knowledge Poisoning Attacks on Medical Multi-Modal Retrieval-Augmented Generation](https://md.research.elamur.ai/free/en/papers/yang-2026-knowledge-poisoning-attacks-medical-multi/)** *(2026)* Medical multimodal RAG systems pair images such as X-rays with clinical text in a retrieval database, and injected adversarial entries can compromise them. ## Co-authors here 12 of 13 co-authors with a page, the most papers together first. - [Peng Wang](https://md.research.elamur.ai/free/en/authors/peng-wang/) ×2 - [Wenjun Ke](https://md.research.elamur.ai/free/en/authors/wenjun-ke/) ×2 - [Yao He](https://md.research.elamur.ai/free/en/authors/yao-he/) ×2 - [Guiyang Hou](https://md.research.elamur.ai/free/en/authors/guiyang-hou/) - [Hang Zhang](https://md.research.elamur.ai/free/en/authors/hang-zhang/) - [Mengna Wang](https://md.research.elamur.ai/free/en/authors/mengna-wang/) - [Shangguang Wang](https://md.research.elamur.ai/free/en/authors/shangguang-wang/) - [Tao Qi](https://md.research.elamur.ai/free/en/authors/tao-qi/) - [Weiming Lu](https://md.research.elamur.ai/free/en/authors/weiming-lu/) - [Wenqi Zhang](https://md.research.elamur.ai/free/en/authors/wenqi-zhang/) - [Xin Li](https://md.research.elamur.ai/free/en/authors/xin-li/) - [Yongfeng Huang](https://md.research.elamur.ai/free/en/authors/yongfeng-huang/) ## 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/) ×4: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×4 ## Cited by Papers of our library cite their works 3 times (of the 149,439 papers whose bibliographies we read); [2 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jiajun-liu/cited-by/).
