Transformer在NLP任务中有一统江湖的趋势,不管是seq2seq还是预训练模型,比如BERT,GPT都离不开Transformer.http://jalammar.github.io/illustrated-transformer/一文对Transformer的介绍可以说是清晰明了,比Attention is all you need论文更容易理解。本文是对其的翻译。还是不追求一字一句的翻译,但求表达正确意思。 2.Trans...
为了解决这个问题,Transformer 为每个输入嵌入添加了一个向量。这些向量遵循模型学习到的特定模式,这有助于确定每个单词的位置,或序列中不同单词之间的距离。这里的直觉是,将这些值添加到嵌入中后,一旦嵌入向量被投影到 Q/K/V 向量中并在点积注意期间,它们之间就会提供有意义的距离。 解码器端 Encoder-Decoder Attent...

Transformer的Encoder部分(不是上图一个一个的标为encoder的模块,而是红框内的整体,上图来自TheIllustratedTransformer,JayAlammar把每个Block称为Encoder不太符合常规叫法)是由若干个相同的TransformerBlock堆叠成的。 这个TransformerBlock其实才是Transformer最关键的地方,核心配方 自然语言处理(NLP): 13 The Illustrated BE...
Transformer 基于自注意力的序列到序列模型 除长期依赖问题外,基于循环神经网络的序列到序列模型的另一个不足是 无法并行计算。 为了提高并行计算效率以及捕捉长距离的依赖关系, 可以使用自注意模型来建立一个全连接的网络结构。 本文简单介绍一个典型的基于自注意力的序列到序列模型: Transformer[Vaswaniet al., ...

To address this, the transformer adds a vector to each input embedding. These vectors follow a specific pattern that the model learns, which helpsit determine the position of each word, or the distance between different words in the sequence. The intuition here is that adding these values to ...
Here we begin to see one key property of the Transformer, which is that the word in each position flows through its own path in the encoder. There are dependencies between these paths in the self-attention layer. The feed-forward layer does not have those dependencies, however, and thus th...
