TokAlign++ method improves LLM vocabulary adaptation with token alignment

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.

    TokAlign++: Advancing Vocabulary Adaptation via Better Token Alignment

    Tokenization is a foundational step in the text process of Large Language Models (LLMs). Texts must be first tokenized into token IDs, which are then input to LLMs. Inefficient tokenization results in long token-ID sequences and will slow down the training and inference of LLMs. …
