English(EN) Attention Sink Forges Native MoE in Attention Layers: Sink-Aware Training to Address Head Collapse

Attention Sink 研究揭示了 LLM 注意力层中固有的 MoE 结构

研究人员发现,大型语言模型中的注意力汇聚现象(即第一个 token 获得不成比例的注意力)会在注意力层内自然形成一个专家混合(MoE)机制。这一发现有助于解释仅部分注意力头被利用的“头坍塌”问题。为解决此问题,研究者提出了一种新的、具有辅助负载均衡损失的 Sink-Aware 训练算法,该算法在不同注意力机制上均显示出改进的性能和有效的头负载均衡。 AI

影响 为注意力机制提供了新的视角,并可能提高 LLM 的效率和性能。

    Attention Sink 在注意力层中原生实现 MoE:Sink-Aware 训练以解决 Head Collapse 问题

    arXiv:2602.01203v2 Announce Type: replace Abstract: Large Language Models (LLMs) often assign disproportionate attention to the first token, a phenomenon known as the attention sink. Several recent approaches aim to address this issue, including Sink Attention in GPT-OSS and Gate…
