Their domain knowledge is shallow, they struggle with long chains of rule-bound reasoning, and they misread terms whose meaning depends on context. Fine-tuning on domain data can introduce hallucinations and catastrophic forgetting. Classic RAG avoids… 2. **[Towards Agentic RAG with Deep Reasoning: A Survey of RAG-Reasoning Systems in LLMs](https://md.research.elamur.ai/free/en/papers/li-2025-towards-agentic-rag-deep-reasoning/)** *(2025 · 17 citations)* Large language models face two linked weaknesses. Their stored knowledge is fixed and can be wrong, and they struggle with problems that need several reasoning steps. Retrieval-Augmented Generation (RAG) addresses the first, and reasoning techniques such as Chain-of-Thought address the second. This survey argues that… 3. **[Mem-Gallery: Benchmarking Multimodal Long-Term Conversational Memory for MLLM Agents](https://md.research.elamur.ai/free/en/papers/bei-2026-mem-gallery-benchmarking-multimodal-long/)** *(2026 · 6 citations)* Agents built on multimodal large language models (MLLMs) need to remember what users show and tell them over many conversations. 4. **[PAPERMIND: Benchmarking Agentic Reasoning and Critique over Scientific Papers in Multimodal LLMs](https://md.research.elamur.ai/free/en/papers/zhao-2026-papermind-benchmarking-agentic-reasoning-critique/)** *(2026 · 2 citations)* PaperMind is a benchmark for testing whether multimodal LLMs can reason about scientific papers in an integrated, agent-like way. ## Co-authors here 12 of 29 co-authors with a page, the most papers together first. - [Hanghang Tong](https://md.research.elamur.ai/free/en/authors/hanghang-tong/) ×2 - [Jingrui He](https://md.research.elamur.ai/free/en/authors/jingrui-he/) ×2 - [Tianxin Wei](https://md.research.elamur.ai/free/en/authors/tianxin-wei/) ×2 - [Xuying Ning](https://md.research.elamur.ai/free/en/authors/xuying-ning/) ×2 - [Yanjun Zhao](https://md.research.elamur.ai/free/en/authors/yanjun-zhao/) ×2 - [Chuang Zhou](https://md.research.elamur.ai/free/en/authors/chuang-zhou/) - [Chunkit Chan](https://md.research.elamur.ai/free/en/authors/chunkit-chan/) - [Hao Chen](https://md.research.elamur.ai/free/en/authors/hao-chen/) - [Henry Peng Zou](https://md.research.elamur.ai/free/en/authors/henry-peng-zou/) - [Huachi Zhou](https://md.research.elamur.ai/free/en/authors/huachi-zhou/) - [Jiaru Zou](https://md.research.elamur.ai/free/en/authors/jiaru-zou/) - [Junnan Dong](https://md.research.elamur.ai/free/en/authors/junnan-dong/) ## 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/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ## Cited by Papers of our library cite their works 72 times (of the 149,439 papers whose bibliographies we read); [24 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yuanchen-bei/cited-by/).
