As a result, they can produce fluent but false answers, they need costly retraining to refresh facts, and they often lack depth in specialised domains. Retrieval-augmented generation (RAG) addresses these issues by consulting an external knowledge… 2. **[GAM: Hierarchical Graph-based Agentic Memory for LLM Agents](https://md.research.elamur.ai/free/en/papers/wu-2026-gam-hierarchical-graph-based-agentic/)** *(2026 · 5 citations)* LLM agents in long conversations must absorb new information without letting passing chatter corrupt what they already know. 3. **[RubricBench: Aligning Model-Generated Rubrics with Human Standards](https://md.research.elamur.ai/free/en/papers/zhou-2026-rubricbench-aligning-model-generated-rubrics/)** *(2026 · 3 citations)* Reward models increasingly judge LLM outputs against rubrics, which are checklists of explicit criteria, to reduce shallow biases such as favoring longer or more polished answers. 4. **[Preference Heads in Large Language Models: A Mechanistic Framework for Interpretable Personalization](https://md.research.elamur.ai/free/en/papers/zhang-2026-preference-heads-large-language-models/)** *(2026 · 1 citation)* LLMs can adapt to a user's tone and topical interests, but current personalization methods (prompting, retrieval of user profiles, fine-tuning) treat this ability as a black box. 5. **[Dynamic n-best Selection and Its Application in Dialog Act Detection](https://md.research.elamur.ai/free/en/papers/hu-2007-dynamic-n-best-selection-its/)** *(2007)* Dialog system modules usually hand the next stage an n-best list of fixed length, even though the right number of candidates changes from input to input. ## 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. **[Retrieval-Augmented Generation for Natural Language Processing: A Survey](https://md.research.elamur.ai/free/en/papers/wu-2024-retrieval-augmented-generation-natural-language/) [Artificial Intelligence Review](https://md.research.elamur.ai/free/en/venues/artificial-intelligence-review/)**Shangyu Wu, Ying Xiong, Yufei Cui, et al.*2024 · 86 citations* 2. **[GAM: Hierarchical Graph-based Agentic Memory for LLM Agents](https://md.research.elamur.ai/free/en/papers/wu-2026-gam-hierarchical-graph-based-agentic/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Zhaofen Wu, Hanrong Zhang, Fulin Lin, et al.*2026 · 5 citations* 3. **[RubricBench: Aligning Model-Generated Rubrics with Human Standards](https://md.research.elamur.ai/free/en/papers/zhou-2026-rubricbench-aligning-model-generated-rubrics/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Junyi Zhou, Qiyuan Zhang, Yufei Wang, et al.*2026 · 3 citations* 4. **[Preference Heads in Large Language Models: A Mechanistic Framework for Interpretable Personalization](https://md.research.elamur.ai/free/en/papers/zhang-2026-preference-heads-large-language-models/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Weixu Zhang, Ye Yuan, Changjiang Han, et al.*2026 · 1 citation* 5. **[Beyond Length Scaling: Synergizing Breadth and Depth for Generative Reward Models ↗](https://aclanthology.org/2026.findings-acl.709/) Findings of the Association for Computational Linguistics: ACL 2026 · no summary yet**Qiyuan Zhang et al.*2026* 6. **[Dynamic n-best Selection and Its Application in Dialog Act Detection](https://md.research.elamur.ai/free/en/papers/hu-2007-dynamic-n-best-selection-its/) [Annual Meeting of the Special Interest Group on Discourse and Dialogue (SIGDIAL)](https://md.research.elamur.ai/free/en/venues/sigdial/)**Junling Hu, Fabrizio Morbini, Fuliang Weng, et al.*2007* ## Co-authors here 12 of 22 co-authors with a page, the most papers together first. - [Haolun Wu](https://md.research.elamur.ai/free/en/authors/haolun-wu/) ×2 - [Ye Yuan](https://md.research.elamur.ai/free/en/authors/ye-yuan/) ×2 - [Can Chen](https://md.research.elamur.ai/free/en/authors/can-chen/) - [Can Xu](https://md.research.elamur.ai/free/en/authors/can-xu/) - [Chen Ma](https://md.research.elamur.ai/free/en/authors/chen-ma/) - [Fabrizio Morbini](https://md.research.elamur.ai/free/en/authors/fabrizio-morbini/) - [Fuyuan Lyu](https://md.research.elamur.ai/free/en/authors/fuyuan-lyu/) - [Hanrong Zhang](https://md.research.elamur.ai/free/en/authors/hanrong-zhang/) - [Henry Peng Zou](https://md.research.elamur.ai/free/en/authors/henry-peng-zou/) - [Hongwei Wang](https://md.research.elamur.ai/free/en/authors/hongwei-wang/) - [Kai Zheng](https://md.research.elamur.ai/free/en/authors/kai-zheng/) - [Philip S.
