English(EN) From Attention Sensitivity to Layer Role: Revisiting Mixed-Precision Quantization of Transformers

新的量化方法优化Transformer注意力输出

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-28 10:53

研究人员开发了一种新的Transformer模型量化方法，重点关注注意力机制的Q、K和V投影。这种方法被称为JAB，直接优化注意力输出而不是单个权重矩阵，在Mistral-7B的3位量化上表现出改进的性能。然而，当包含MLP层时，该方法的有效性会降低，在这种情况下，一种与角色相关的偏移规则被证明更成功，在Mistral-7B上实现了接近全精度困惑度但压缩显著。 AI

影响这项研究可能通过改进量化技术，从而降低计算成本和内存需求，从而实现更高效的Transformer模型。

从注意力敏感性到层角色：重新审视Transformer的混合精度量化

Most post-training quantization pipelines fit each weight matrix to its pretrained counterpart, one matrix at a time. Whether that proxy tracks what an attention block actually computes, or how errors in the Q, K and V projections compound inside the softmax, is rarely checked. W…
