一文看懂Transformer内部原理(含PyTorch实现) "Attention is All You Need" 一文中提出的Transformer网络结构最近引起了很多人的关注。Transformer不仅能够明显地提升翻译质量,还为许多NLP任务提供了新的结构。虽然原文写得很清楚,但实际上大家普遍反映很难正确地实现。 所以我们为此文章写了篇注解文档,并给出了一行行实现...
“多头”机制能让模型考虑到不同位置的Attention,另外“多头”Attention可以在不同的子空间表示不一样的关联关系,使用单个Head的Attention一般达不到这种效果。 MultiHead(Q,K,V)=Concat(head1,...,headh)WOwhereheadi=Attention(QWQi,KWKi,VWVi)MultiHead(Q,K,V)=Concat(head1,...,headh)WOwhereheadi=A...
