English(EN) Translation Asymmetry in LLMs as a Data Augmentation Factor: A Case Study for 6 Romansh Language Varieties

LLM 翻译不对称提升罗曼什语数据增强效果

研究人员探索了低资源机器翻译的数据增强策略,重点关注罗曼什语及其六种不同的变体。他们发现了一种翻译不对称现象,即大型语言模型(LLM)在翻译成罗曼什语时遇到困难,但在将其翻译成德语时表现良好。这种不对称性使得数据增强的方向至关重要。研究发现,生成合成翻译到资源更丰富的语言(德语)可以产生更优的结果,在资源最少的变体中,比 Gemini 3-Pro 基线高出 23 个 BLEU 分数(用于德语-罗曼什语翻译)。人工评估证实,开发的模型能够生成特定于不同罗曼什语变体的流畅翻译,这在该语言中尚属首次。 AI

影响 展示了一种针对低资源语言的新颖数据增强技术,有望提高 LLM 在代表性不足的语言区域的表现。

    大型语言模型中的翻译不对称性作为数据增强因素:6种罗曼什语变体的案例研究

    arXiv:2603.25489v2 Announce Type: replace Abstract: Recent strategies for low-resource machine translation rely on LLMs to generate synthetic data based on text in higher-resource languages. We revisit this idea for Romansh, a language with 6 distinct varieties. LLMs tend to conf…
