线性变换:将特征聚合后的结果与一个权重矩阵相乘,进行线性变换,以捕捉节点的局部结构信息。
With mountain bicycle racing in its Winter season hibernation we will only hope that a lot more membership particulars and coverage announcements will comply with shortly.
අම්මා මොන දහම් ගැටේ දැම්මත් පෙම්වතා දියණියට කරපු දේ.
The GCN+ streaming support and GCN application are set to close down around the 19th of December. Inside a shock announcement designed to subscribers nowadays, GCN declared "with fantastic sadness" that due to manufacturer's parent company, Warner Bros. Discovery lowering its range of streaming solutions, the GCN+ provider and application could well be closing.
这种标准化的策略所提供的是一种加权平均,所实现的效果是会给予那些具有低度的结点更大的权重从而降低高度结点的影响。这种加权平均的想法在于那些具有较低度的结点会对其邻居有较大的影响,而高度的结点会产生更小的影响因为他们的影响会被分散给很多的邻居结点。
特征传播:对于每个节点,将其特征与其邻居节点的特征进行聚合,可以使用邻居节点的均值、最大值或拼接等操作。
只能对常规的欧式数据进行处理,其特点就是节点有固定的排列规则和顺序,如2维网格和1维序列。近几年来,将深度学习应用到处理和图结构数据相关的任务中越来越受到人们的关注。图神经

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。
