The authors trace part of this gap to supervised fine-tuning (SFT). SFT copies reference translations, so the model can only be as good as those references. It also never teaches the model to avoid output that is… 2. **[The Language Barrier: Dissecting Safety Challenges of LLMs in Multilingual Contexts](https://md.research.elamur.ai/free/en/papers/shen-2024-language-barrier-dissecting-safety-challenges/)** *(2024 · 86 citations)* This paper asks whether the safety behaviour of large language models holds up when the same harmful request is posed in languages with little training data. ## Co-authors here 10 co-authors with a page, the most papers together first. - [Lingfeng Shen](https://md.research.elamur.ai/free/en/authors/lingfeng-shen/) ×2 - [Weiting Tan](https://md.research.elamur.ai/free/en/authors/weiting-tan/) ×2 - [Yunmo Chen](https://md.research.elamur.ai/free/en/authors/yunmo-chen/) ×2 - [Amr Sharaf](https://md.research.elamur.ai/free/en/authors/amr-sharaf/) - [Benjamin Van Durme](https://md.research.elamur.ai/free/en/authors/benjamin-van-durme/) - [Boyuan Zheng](https://md.research.elamur.ai/free/en/authors/boyuan-zheng/) - [Daniel Khashabi](https://md.research.elamur.ai/free/en/authors/daniel-khashabi/) - [Kenton Murray](https://md.research.elamur.ai/free/en/authors/kenton-murray/) - [Philipp Koehn](https://md.research.elamur.ai/free/en/authors/philipp-koehn/) - [Sihao Chen](https://md.research.elamur.ai/free/en/authors/sihao-chen/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2024](https://md.research.elamur.ai/free/en/venues/findings/2024/) ## Cited by Papers of our library cite their works 250 times (of the 141,840 papers whose bibliographies we read); [10 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/haoran-xu/cited-by/).
