2019年11月论文“Fast Transformer Decoding: One Write-Head is All You Need“,谷歌工作。 Transformer神经序列模型中使用的多头注意层,是RNN的替代。虽然整个序列的并行性让这些层的训练通常快速而简单,但由…
Multi Query Attention(MQA)和Multi Head Attention(MHA)只差了一个单词,就是从「Head」变成了「Query」。 MQA 让所有的头之间共享同一份 Key 和 Value 矩阵,每个头只单独保留了一份 Query 参数,从而大大减少 Key 和 Value 矩阵的参数量。 代码: classMultiheadAttention(nn.Module):def__init__(self,d_mod...

相较于传统的单轮Attention机制,Multi-Query Attention具有以下优势: 更好地捕捉对话上下文:通过为每一轮对话生成独立的查询向量,Multi-Query Attention能够更准确地捕捉对话的上下文信息,从而提升模型对对话意图的理解。 提升模型泛化能力:由于Multi-Query Attention能够根据对话内容动态调整关注焦点,因此能够更好地适应不同...
多查询注意力(Multi Query Attention,MQA)和分组查询注意力(Group Query Attention,GQA)是在近年来对Transformer模型的改进中引起关注的新技术。MQA最早于2019年的论文《Fast Transformer Decoding: One Write-Head is All You Need》中提出,旨在解决Transformer增量推理阶段效率低下的问题。虽然当时并没有引起广泛关注...

Multi-head attention consists of multiple attention layers (heads) in parallel with different linear transformations on the queries, keys, values and outputs. Multi-query attention is identical except that the different heads share a single set of keys a
The open source implementation of the multi grouped query attention by the paper "GQA: Training Generalized Multi-Query Transformer Models from Multi-Head Checkpoints" - kyegomez/MGQA
Additionally, we design a new query strategy to optimize the initial selection of queries with Uncertainty-minimal Query Selection. Two self-attention mechanisms are used in the decoding phase for understanding and recording spatial and semantic connections between keypoints. In this paper, the MAQT ...
