%%% 输出
\begin{frame}{模块2：输出层}
\begin{itemize}
\item 输出层需要得到每个目标语单词的生成概率，进而选取概率最高的词作为输出。但RNN中的隐藏层并不会输出单词概率，而是输出$s$，其每一行对应一个单词表示
\begin{itemize}
\item $s$经过权重矩阵$W$变成$\hat{s}$，其隐藏层维度变换成词表的大小
\item $\hat{s}$经过Softmax变换得到不同词作为输出的概率，即单词$i$的概率$p_i = \textrm{Softmax}(i) = \frac{e^{\hat{s}_i}}{\sum_{j} e^{\hat{s}_{j}}} $
