  • TLDR:ARCHead is presented, a packed LM-head compressor that combines a quantized low-rank core, group-wise INT4 residuals, and a low-rank correction fitted in an activation-derived metric to complements block quantizers by compressing the large output projection they can leave untouched.
  • 待LLM分类:否
  • 标题中文:ARCHead: 大语言模型输出头的激活度量残差校正
  • TLDR中文:提出 ARCHead,一种紧凑型 LM-head 压缩器,结合量化低秩核心、组级 INT4 残差以及基于激活导出度量拟合的低秩校正,在 block 量化器无法触及的大输出投影上实现互补压缩。
