English(EN) Beyond Two Bytes per Letter: Tokenization Overhead in Cyrillic AI Systems

新研究量化了AI系统中西里尔字母分词的开销

一篇题为《超越每个字母两个字节:西里尔字母AI系统中的分词开销》的新研究论文,量化了像乌克兰语这样代表性不足的西里尔字母语言与英语相比,存在显著的分词开销。研究发现,现代分词器可以将乌克兰语文本的碎片化程度提高121%,高于英语,这会影响成本和上下文容量。研究人员评估了缓解策略,包括使用LLMLingua-2来缩短输入长度,以及训练一个平衡的字节级BPE分词器,这些策略成功降低了分词比例。 AI

影响 强调了AI系统在非英语语言方面可能存在的效率低下问题,并提出了改进建议,以提高可访问性和成本效益。
