Researchers have developed TokAlign++, a novel method to improve vocabulary adaptation in Large Language Models by learning a better token alignment lexicon. This technique treats source and target vocabularies as different languages, learning a bilingual token alignment lexicon from monolingual token representations. Experiments across 15 languages demonstrate that TokAlign++ enhances multilingual text compression rates and retains most of the original model's multilingual capabilities, achieving significant performance restoration in as few as 1,000 steps.
