\item 长度惩罚因子。用译文长度来归一化翻译概率是最常用的方法:对于源语言句子$\seq{x}$和译文句子$\seq{y}$,模型得分$\textrm{score}(\seq{x},\seq{y})$的值会随着译文$\seq{y}$ 的变长而减小,为了避免此现象,可以引入一个长度惩罚函数$\textrm{lp}(\seq{y})$,并定义模型得分如公式\eqref{eq:14-12}所示:
\begin{eqnarray}
\textrm{score}(\seq{x},\seq{y}) &=& \frac{\log \funp{P}(\seq{y}\vert\seq{x})}{\textrm{lp}(\seq{y})}

\noindent 其中,$\textrm{cp}(\seq{x},\seq{y}) $表示覆盖度模型,它度量了译文对源语言每个单词的覆盖程度。$\textrm{cp}(\seq{x},\seq{y}) $的定义中,$a_{ij}$表示源语言第$i$个位置与目标语第$j$个位置的注意力权重,这样$\sum \limits_{j}^{|\seq{y}|} a_{ij}$就可以用来衡量源语言第$i$个单词被翻译了“多少”,如果它大于1,表明翻译多了;如果小于1,表明翻译少了。公式\eqref{eq:14-6}会惩罚那些欠翻译的翻译假设。覆盖度模型的一种改进形式是\upcite{li-etal-2018-simple}
\begin{eqnarray}
\textrm{cp}(\seq{x},\seq{y}) &=& \sum_{i=1}^{|\seq{x}|} \log( \textrm{max} ( \sum_{j}^{|\seq{y}|} a_{ij},\beta))

\end{eqnarray}
\noindent 公式\eqref{eq:14-7}将公式\eqref{eq:14-6}中的向下截断方式换为了向上截断。这样,模型可以对过翻译(或重复翻译)有更好的建模能力。不过,这个模型需要在开发集上细致地调整$\beta$,也带来了一定的额外工作量。此外,也可以将这种覆盖度单独建模并进行参数化,与翻译模型一同训练\upcite{Mi2016CoverageEM,TuModeling,Kazimi2017CoverageFC}。这样可以得到更加精细的覆盖度模型。

\parinterval 目前主流的神经机器翻译的推断是一种{\small\sffamily\bfseries{自回归翻译}}\index{自回归翻译}(Autoregressive Translation)\index{Autoregressive Translation}过程。所谓自回归是一种描述时间序列生成的方式。对于目标序列$\seq{y}=\{y_1,\dots,y_n\}$,自回归模型假设$j$时刻状态$y_j$的生成依赖于之前的状态$\{y_1,\dots,y_{j-1}\}$,而且$y_j$$\{y_1,\dots,y_{j-1}\}$构成线性关系,那么生成$y_j$就是自回归的序列生成过程。神经机器翻译借用了这个概念,但是并不要求线性模型。对于输入的源语言序列$\seq{x}=\{x_1,\dots,x_m\}$,用自回归翻译模型生成译文序列$\seq{y}=\{y_1,\dots,y_n\}$的概率可以被定义为:
\begin{eqnarray}
\funp{P}(\seq{y}|\seq{x}) &=& \prod_{j=1}^n {\funp{P}(y_j|y_{<j},\seq{x})}
