NVIDIA 推出 X-Token:跨分词器知识蒸馏,在 Llama-3.2-1B 上超越 GOLD 3.82 平均分

NVIDIA 提出 X-Token,一种投影引导的跨分词器知识蒸馏(KD)方法,解决了 GOLD 方法中的两个结构性缺陷。在 Llama-3.2-1B 模型上,X-Token 将 GSM8k 准确率从 2.56% 提升至 15.54%,并在多个基准测试中平均超越 GOLD 3.82 分。该方法通过投影层对齐教师和学生模型的分词器,实现了更有效的知识迁移。X-Token 为小模型蒸馏大模型知识提供了新思路,尤其适用于资源受限场景。

Current read

X-Token 解决了知识蒸馏中分词器不匹配的痛点,做模型压缩或边缘部署的团队可以直接用这个思路提升小模型推理能力,值得关注。
