Prior work shows this can backfire: very strong teachers may produce answers that are too complex or too far from what the student can absorb. Earlier remedies (Mix, CAR) still make every candidate teacher answer… 2. **[Quantifying and Improving the Robustness of Retrieval-Augmented Language Models Against Spurious Features in Grounding Data](https://md.research.elamur.ai/free/en/papers/yang-2026-quantifying-improving-robustness-retrieval-augmented/)** *(2026)* Retrieval-augmented language models (RALMs) are usually tested against noise that changes a document's meaning. ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Hengyuan Zhang](https://md.research.elamur.ai/free/en/authors/hengyuan-zhang/) ×2 - [Shiping Yang](https://md.research.elamur.ai/free/en/authors/shiping-yang/) ×2 - [Chaofan Tao](https://md.research.elamur.ai/free/en/authors/chaofan-tao/) - [Chenming Shang](https://md.research.elamur.ai/free/en/authors/chenming-shang/) - [Dongmei Zhang](https://md.research.elamur.ai/free/en/authors/dongmei-zhang/) - [Hayden Kwok-Hay So](https://md.research.elamur.ai/free/en/authors/hayden-kwok-hay-so/) - [Jing Xiong](https://md.research.elamur.ai/free/en/authors/jing-xiong/) - [Ming Gong](https://md.research.elamur.ai/free/en/authors/ming-gong/) - [Ngai Wong](https://md.research.elamur.ai/free/en/authors/ngai-wong/) - [Ning Wu](https://md.research.elamur.ai/free/en/authors/ning-wu/) - [Ruobing Xie](https://md.research.elamur.ai/free/en/authors/ruobing-xie/) - [Shining Liang](https://md.research.elamur.ai/free/en/authors/shining-liang/) ## 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 ## Cited by Papers of our library cite their works 11 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/angel-x-chang/cited-by/).
