2017年,Google机器翻译团队发表的《Attention is all you need》中大量使用了自注意力(self-attention)机制来学习文本表示。 参考文章:《attention is all you need》解读 1、Motivation: 靠attention机制,不使用rnn和cnn,并行度高 通过attention,抓长距离依赖关系比rnn强 2、创新点: 通过self-attention,自己和自己做...
The Transformer paper, “Attention is All You Need” isthe #1 all-time paper on Arxiv Sanity Preserveras of this writing (Aug 14, 2019). This paper showed that using attention mechanisms alone, it’s possible to achieve state-of-the-art results on language translation. Subsequent models bui...

Google在2017年发表了著名的论文《Attention Is All You Need》提出了目前在NLP以及CV领域使用非常广泛的transformer模型,而self-attention是transformer的主要组成部分。 在transformer之前,NLP领域常见的处理序列数据的方法主要是RNN/LSTM等: A:由于RNN/LSTM在计算时需考虑前序信息,所以不能并行,导致训练时间较长 ...

算法细节可以参见paper，这里简单说下attention取得好的效果的直观感觉。传统的用RNN建模语言的时序特征，前面的单词信息都依次feed到后面一个单词，这种信息的堆叠感觉有点浪费，而且反而把信息糅杂在一起不好区分，虽然decoder阶段对每个单词对应的encoder输出位置做attention，但每个encoder输出已经夹杂了前面...
