Transformer、Attention与seq2seq model 一、什么是seq2seq,以及它和Attention机制有什么关系 seq2seq是一种NLP常见的框架——这种框架不要求输入和输出序列是维度是一样的。许多NLP task的输入输出维度不统一,比如机器翻译、图像的图注生成、摘要生成、自动问答等。seq2seq框架大多包含encoder
Seq2Seq模型有时可以包含自编码和自回归模型。Seq2Seq模型的decoder通常是自回归的,它根据之前的所有token,一次生成一个token的输出序列。 Seq2Seq的encoder部分可以看作类似自编码器,因为它将输入压缩成密集表示,但是与自编码器LM不同的是,seq2seq的encoder目标不是重建输入,而是为生成的输出序列(通常是不同domain...
