Their training data, cleaning pipelines and training recipes stay hidden, which makes it hard for researchers to reproduce results or build strong baselines. OpenCoder addresses this gap. It is a code LLM family released with everything needed to rebuild it: weights… 2. **[CT-FineBench: A Diagnostic Fidelity Benchmark for Fine-Grained Evaluation of CT Report Generation](https://md.research.elamur.ai/free/en/papers/yuan-2026-ct-finebench-diagnostic-fidelity-benchmark/)** *(2026)* Existing metrics for automatically generated CT reports are poor at checking whether diagnostic details are correct. 3. **[Understanding the Behaviors of Environment-aware Information Retrieval](https://md.research.elamur.ai/free/en/papers/yuan-2026-understanding-behaviors-environment-aware-information/)** *(2026)* Agentic RAG systems often assume a single web search engine. In practice, they also query local backends such as BM25 or dense embedders, and each backend may respond best to a differently phrased query. This paper asks whether an LLM query rewriter can learn retriever-specific query styles through reinforcement… ## Co-authors here 12 of 15 co-authors with a page, the most papers together first. - [Bowen Shi](https://md.research.elamur.ai/free/en/authors/bowen-shi/) - [Chenchen Zhang](https://md.research.elamur.ai/free/en/authors/chenchen-zhang/) - [Chenghao Xiao](https://md.research.elamur.ai/free/en/authors/chenghao-xiao/) - [Hong Cheng](https://md.research.elamur.ai/free/en/authors/hong-cheng/) - [Hou Pong Chan](https://md.research.elamur.ai/free/en/authors/hou-pong-chan/) - [Jason Klein Liu](https://md.research.elamur.ai/free/en/authors/jason-klein-liu/) - [Jiaheng Liu](https://md.research.elamur.ai/free/en/authors/jiaheng-liu/) - [Jian Yang](https://md.research.elamur.ai/free/en/authors/jian-yang/) - [Linzheng Chai](https://md.research.elamur.ai/free/en/authors/linzheng-chai/) - [Siming Huang](https://md.research.elamur.ai/free/en/authors/siming-huang/) - [Tianhao Cheng](https://md.research.elamur.ai/free/en/authors/tianhao-cheng/) - [Weidi Xu](https://md.research.elamur.ai/free/en/authors/weidi-xu/) ## 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/) ×3: [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/) ## Cited by Papers of our library cite their works 67 times (of the 149,439 papers whose bibliographies we read); [30 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/ruifeng-yuan/cited-by/).
