Decoder-only架构
WebApr 8, 2024 · The sequence-to-sequence (seq2seq) task aims at generating the target sequence based on the given input source sequence. Traditionally, most of the seq2seq task is resolved by the Encoder-Decoder framework which requires an encoder to encode the source sequence and a decoder to generate the target text. Recently, a bunch of … WebJun 21, 2024 · Seq2Seq. 最终,我们的Seq2Seq的模型需要结合Encoder和Decoder,每一次forward都是之前讲到的流程,Encoder将输入的20个序列编码为一个context vector,然后将其作为Decoder的初始输入,并将Encoder最终的hidden state和cell state作为Decoder初始的hidden state和cell state,最终我们在for循环里每次利用Decoder来预测下一个时间 …
