various Sequence to Sequence Model

1. A basic LSTM decoder.

每次的输出值就是下一次的输入值, 第一次的输入值就是 encoder 产生的 Context Vector. Encoder最后输出的 hidden state 通常用来初始化 Decoder的 $y_{0}$.

基本公式:

\[y_{0} = LSTM(s_{0}, C);\]

$C$ 就是encoder 产生的 context vector.
\[y_t = LSTM(s_{t-1}, y_{t-1});\]

$s$ 是LSTM的 hidden state 状态 LSTM ($h$ and $c$).

\[s_t=[h_t,c_t]\]

论文笔记-Sequence to Sequence Learning with Neural Networks

大体思想和RNN encoder-decoder是一样的,只是用来LSTM来实现. paper提到三个important point: 1)encoder和decoder的LSTM是两个不同的模型 2)deep LSTM表现比shallow好,选用了4层的LSTM 3)实践中发现将输入句子reverse后再进行训练效果更好.So for example, instead of mapping the sentence a,b,c to the sentence α,β,γ, the LSTM i
