English(EN) Revisiting the Shape Convention of Transformer Language Models

沙漏型Transformer比传统模型更具效率优势

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-10 04:00

研究人员开发了“沙漏型Transformer”，这是一种新颖的语言模型架构，偏离了传统的窄-宽-窄前馈网络（FFN）设计。通过采用沙漏型子MLP和沙漏型注意力机制，这些模型在113M到8B参数的各种规模下，表现与标准Transformer相当。值得注意的是，沙漏型Transformer在训练计算效率方面提高了高达8.7%，并且在长上下文扩展后，提供了更快的令牌解码速度和更低的KV缓存内存需求，使其成为注重效率设计的实用替代方案。 AI

影响沙漏型结构为注重计算和延迟的Transformer设计提供了一种实用的替代方案，有可能提高训练和推理效率。

重新审视 Transformer 语言模型的形状约定

arXiv:2602.06471v2 Announce Type: replace Abstract: The architectural shape of dense Transformers has remained remarkably stable: narrow-wide-narrow feed-forward networks (FFNs) consume most non-embedding parameters. Motivated by theoretical and empirical evidences that residual …
