 在图1，顶点$v$包含两个向量:输入$\boldsymbol{x}$和它的隐蔽表示$\boldsymbol{h}$。我们也有多个顶点$v_{j}$，也就是包含$\boldsymbol{x}\_j$ 和 $\boldsymbol{h}\_j$。在这个图形，顶点都是以有向边来连接起来。
 
 <!-- We represent these directed edges with adjacency vector $\boldsymbol{a}$, where each element $\alpha_{j}$ is set to $1$ if there is a directed edge from $v_{j}$ to $v$. -->
-我们以邻接向量$\boldsymbol{a}$来代表这些有向边，这里如果是一个有向边由$v_{j}$到$v$的话，那每一个元件$\alpha_{j}$都设定为$1$。
