根据卷积层叠的不同方法,基于空间的GCN可以进一步分为两类:recurrent-based和composition-based的空间GCN。recurrent-based的方法使用相同的图卷积层来更新隐藏表示,composition-based的方法使用不同的图卷积层来更新隐藏表示。下图说明了这种差异。 1.3 Comparison Between Spectral and Spatial Models 作为最早的图卷积网络,...
这就是GNN的全部过程。GNN是Graph+neural network,上面我们已经提到了很多graph,那么neural是怎么体现的呢?从图5中可以看到,第一步encoder是一层linear,得到了每个node的encoding向量,第二步是做message passing,就是每个node和邻居信息经过linear层做encoding得到向量,循环做几次,第三步是经过linear层做输出。可以看到...

在这项工作中,我们介绍了一种基于词典的图神经网络lexicon-based graph neural network(LGN),它实现了中文NER作为节点分类任务。该模型打破了RNN的串行化处理结构,通过仔细的连接,字符和单词之间的交互效果更好。词汇知识将相关字符连接起来,以捕获本地成分。同时,设计了一个全局中继节点来捕获远程依赖性和高级特性。LG...
GCN方法又可以分为两大类,基于频谱(spectral-based)和基于空间(spatial-based)。基于频谱的方法从图信号处理的角度引入滤波器来定义图卷积,其中图卷积操作被解释为从图信号中去除噪声。基于空间的方法将图卷积表示为从邻域聚合特征信息,当图卷积网络的算法在节点层次运行时,图池化模块可以与图卷积层交错,将图粗化为高...
