It is slow, which limits timeliness and ensemble size, and its parameterizations introduce errors. Earlier deep learning forecasters such as FourCastNet were fast but less accurate than ECMWF's operational IFS. 3. **[Automatic Assessment of the Speech of Young English Learners](https://md.research.elamur.ai/free/en/papers/cheng-2014-automatic-assessment-speech-young-english/)** *(2014 · 35 citations)* The paper describes how Pearson automated the speaking section of AZELLA, Arizona's yearly English proficiency test for K-12 English learners. 4. **[Too Consistent to Detect: A Study of Self-Consistent Errors in LLMs](https://md.research.elamur.ai/free/en/papers/tan-2025-too-consistent-detect-study-self/)** *(2025 · 12 citations)* LLM error detectors often treat agreement across sampled answers as a sign of correctness. This paper identifies a blind spot in that assumption: self-consistent errors , where a model gives the same wrong answer, up to semantic equivalence, in its greedy output and in all stochastic samples. The authors define these… 5. **[BaseCal: Unsupervised Confidence Calibration via Base Model Signals](https://md.research.elamur.ai/free/en/papers/tan-2026-basecal-unsupervised-confidence-calibration-base/)** *(2026 · 1 citation)* Post-trained LLMs (PoLLMs), such as instruction-tuned or RLHF-aligned models, tend to be overconfident: they assign high probability even to wrong answers, which limits the usefulness of confidence for detecting hallucinations. 6. **[MTR-Suite: A Framework for Evaluating and Synthesizing Conversational Retrieval Benchmarks](https://md.research.elamur.ai/free/en/papers/ruan-2026-mtr-suite-framework-evaluating-synthesizing/)** *(2026)* Conversational retrieval decides which evidence a RAG system can use, but its benchmarks have two kinds of flaws. ## Co-authors here 12 of 29 co-authors with a page, the most papers together first. - [Jingang Wang](https://md.research.elamur.ai/free/en/authors/jingang-wang/) ×3 - [Du Su](https://md.research.elamur.ai/free/en/authors/du-su/) ×2 - [Fei Sun](https://md.research.elamur.ai/free/en/authors/fei-sun/) ×2 - [Hexiang Tan](https://md.research.elamur.ai/free/en/authors/hexiang-tan/) ×2 - [Xueqi Cheng](https://md.research.elamur.ai/free/en/authors/xueqi-cheng/) ×2 - [Xunliang Cai](https://md.research.elamur.ai/free/en/authors/xunliang-cai/) ×2 - [Yuanzhuo Wang](https://md.research.elamur.ai/free/en/authors/yuanzhuo-wang/) ×2 - [Bei Li](https://md.research.elamur.ai/free/en/authors/bei-li/) - [Haodong Duan](https://md.research.elamur.ai/free/en/authors/haodong-duan/) - [Haojiong Chen](https://md.research.elamur.ai/free/en/authors/haojiong-chen/) - [Huawei Shen](https://md.research.elamur.ai/free/en/authors/huawei-shen/) - [Jared Bernstein](https://md.research.elamur.ai/free/en/authors/jared-bernstein/) ## 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/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2 - [Workshop on Innovative Use of NLP for Building Educational Applications (BEA)](https://md.research.elamur.ai/free/en/venues/bea/): [BEA 2014](https://md.research.elamur.ai/free/en/venues/bea/2014/) - [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/): [EMNLP 2025](https://md.research.elamur.ai/free/en/venues/emnlp/2025/) ## Cited by Papers of our library cite their works 302 times (of the 149,439 papers whose bibliographies we read); [75 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xin-chen/cited-by/).
