Researchers have developed a novel method called LINK to enhance cross-lingual knowledge transfer in language models, particularly for languages with limited training data. This technique involves lexical interventions, where words in the high-resource language training data are replaced with their translations using a bilingual vocabulary. This approach requires no additional model training or parallel data, making it cost-effective and applicable to a wide range of languages. Evaluations across eight languages and five model sizes demonstrated significant improvements in downstream tasks and up to a twofold increase in training speed to achieve equivalent performance. AI
