Researchers have developed a novel framework called parallel tokenizers to improve cross-lingual transfer in multilingual language models, particularly for low-resource languages. This approach involves training tokenizers monolingually and then aligning their vocabularies using bilingual dictionaries or word-to-word translation. This alignment creates a shared semantic space, enhancing representation learning. Experiments with a transformer encoder trained on thirteen low-resource languages demonstrated superior performance on tasks like sentiment analysis and hate speech detection compared to conventional multilingual baselines.
