在大模型技术中,GQA(Grouped Query Attention)是一种注意力机制,它介于MHA(Multi-Head Attention)和MQA(Multi-Query Attention)之间,旨在结合两者的优点,以实现在保持MQA推理速度的同时接近MHA的精度。 MHA是一种基础的注意力机制,它通过将输入分割成多个头(heads)来并行计算注意力,每个头学习输入的不同部分,最终将...

Grouped-Query Attention(GQA)是对传统自注意力机制的一种改进。在GQA中,查询被分为不同的组,每个组共享相同的查询。这种设计旨在提高模型的计算效率,同时保持足够的表达能力,尤其在处理长序列时。 2. 基本概念 在Grouped-Query Attention中: 查询(Q)被分为多个组,每个组有自己的键(K)和值(V)。 每个组的查询...

a→ There are so many students that the teacher can't pay attention to everyone. So some students are absent-minded. The teacher can't effectively control class in order. And students are not properly grouped. 那里→是老师不可能支付对大家的注意的许多学生。 那么有些学生是丢三落四的。 老师...

aThe Contractor’s attention is drawn towards the fact that these Bills of Quantities have been written in an ELEMENTAL FORM i.e. the items are grouped under Elements and within each Element, the items have been set out, as far as possible in Trade Order. 承包商的注意被引起往事实这些建筑...
GQA作为MHA和MQA的折中方案,它将查询头(query heads)分组,每组共享一个键和值,而不是所有头都共享。这样,GQA能够在减少计算量的同时,保持更多的多样性,从而在推理速度和模型精度之间取得平衡 。 GQA-1:一个单独的组,等同于 Multi-Query Attention (MQA)。
