The authors propose TC–RAG, which they prove to be… 2. **[Recurrent Knowledge Identification and Fusion for Language Model Continual Learning](https://md.research.elamur.ai/free/en/papers/feng-2025-recurrent-knowledge-identification-fusion-language/)** *(2025 · 11 citations)* This paper tackles continual learning for large language models, where a model must absorb tasks one after another without losing earlier skills (catastrophic forgetting) while still benefiting from links between tasks (knowledge transfer). 3. **[Parenting: Optimizing Knowledge Selection of Retrieval-Augmented Language Models with Parameter Decoupling and Tailored Tuning](https://md.research.elamur.ai/free/en/papers/xu-2025-parenting-optimizing-knowledge-selection-retrieval/)** *(2025 · 9 citations)* Retrieval-augmented LLMs face two competing demands. They should trust retrieved evidence even when it contradicts what they memorized (adherence), and they should ignore retrieved passages that look relevant but are actually noise (robustness). Training aimed at one of these tends to hurt the other. The authors… 4. **[MuSe: Multi-Stage Graph Reasoning via Vision-Language Models](https://md.research.elamur.ai/free/en/papers/wang-2026-muse-multi-stage-graph-reasoning/)** *(2026)* Graph reasoning is usually handled by GNNs or graph transformers, which need task-specific training. LLMs that read graphs serialized as text struggle to keep two-dimensional structure and multi-hop relations. Vision-language methods such as GITA draw the entire graph as one picture, but large graphs then become… 5. **[RADO: Reasoning Audit-Driven Optimization for Rigorous Reasoning in High-Stakes Domains](https://md.research.elamur.ai/free/en/papers/tan-2026-rado-reasoning-audit-driven-optimization/)** *(2026)* Reinforcement learning for LLM reasoning usually rewards only the final answer. A model can therefore reach correct conclusions through faulty intermediate logic, which is a serious problem in finance, law and biomedicine. RADO exploits an asymmetry: finding one local flaw in a derivation is easier than producing a… ## 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. **[TC–RAG: Turing–Complete RAG's Case study on Medical LLM Systems](https://md.research.elamur.ai/free/en/papers/jiang-2025-tc-rag-turing-complete-rag/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Xinke Jiang, Yue Fang, Rihong Qiu, et al.*2025 · 25 citations* 2. **[Recurrent Knowledge Identification and Fusion for Language Model Continual Learning](https://md.research.elamur.ai/free/en/papers/feng-2025-recurrent-knowledge-identification-fusion-language/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Yujie Feng, Xujia Wang, Zexin Lu, et al.*2025 · 11 citations* 3. **[Parenting: Optimizing Knowledge Selection of Retrieval-Augmented Language Models with Parameter Decoupling and Tailored Tuning](https://md.research.elamur.ai/free/en/papers/xu-2025-parenting-optimizing-knowledge-selection-retrieval/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Yongxin Xu, Ruizhe Zhang, Xinke Jiang, et al.*2025 · 9 citations* 4. **[MuSe: Multi-Stage Graph Reasoning via Vision-Language Models](https://md.research.elamur.ai/free/en/papers/wang-2026-muse-multi-stage-graph-reasoning/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Guanyu Wang, Xu Chu, Zhijie Tan, et al.*2026* 5. **[RADO: Reasoning Audit-Driven Optimization for Rigorous Reasoning in High-Stakes Domains](https://md.research.elamur.ai/free/en/papers/tan-2026-rado-reasoning-audit-driven-optimization/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Zhijie Tan, Xu Chu, Guanyu Wang, et al.*2026* 6. **[Robust Explanations for User Trust in Enterprise NLP Systems ↗](https://aclanthology.org/2026.acl-industry.81/) Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 6: Industry Track) · no summary yet**Guilin Zhang et al.*2026* ## Co-authors here 12 of 16 co-authors with a page, the most papers together first. - [Yongxin Xu](https://md.research.elamur.ai/free/en/authors/yongxin-xu/) ×3 - [Guanyu Wang](https://md.research.elamur.ai/free/en/authors/guanyu-wang/) ×2 - [Junfeng Zhao](https://md.research.elamur.ai/free/en/authors/junfeng-zhao/) ×2 - [Ruizhe Zhang](https://md.research.elamur.ai/free/en/authors/ruizhe-zhang/) ×2 - [Tong Mo](https://md.research.elamur.ai/free/en/authors/tong-mo/) ×2 - [Weiping Li](https://md.research.elamur.ai/free/en/authors/weiping-li/) ×2 - [Xinke Jiang](https://md.research.elamur.ai/free/en/authors/xinke-jiang/) ×2 - [Xinyu Ma](https://md.research.elamur.ai/free/en/authors/xinyu-ma/) ×2 - [Yasha Wang](https://md.research.elamur.ai/free/en/authors/yasha-wang/) ×2 - [Yujie Feng](https://md.research.elamur.ai/free/en/authors/yujie-feng/) ×2 - [Zhijie Tan](https://md.research.elamur.ai/free/en/authors/zhijie-tan/) ×2 - [Hao Chen](https://md.research.elamur.ai/free/en/authors/hao-chen/) ## 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/) ×6: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2, [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ×3 ## Cited by Papers of our library cite their works 30 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/xu-chu/cited-by/).
