在图中，我们不仅有结点的特征（结点的数据），还有图的结构（结点之间是如何进行连接的）。

使用均值看起来已经可以取得不错的效果，那么使用加权平均又如何呢？直觉上的感觉对具有高度和低度的结点采取不同的权重会有更好的效果。

我们应该使用平均值函数甚至是更好的加权平均值函数而非直接加和来处理邻居的特征向量。那为什么不能直接使用加和函数呢？原因就在于，当使用加和函数的时候，具有较大度值的结点会有很大的表示向量，而较低度的结点会有较小的聚合向量，这可能会导致梯度爆炸或梯度消失的问题（比如使用sigmoid函数时）。此外，神经网络对于输入数据的标度是非常敏感的，我们需要将这些向量进行标准化以消除潜在的问题。
