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,...
我们可以看到messageNN函数在init中定义好了,就是一层linear变换,把输入向量,映射为中间向量m(可以理解为图3中的m),m的维度可以自己设定(代码中的hidden_dim),第13行可以看到,messageNN的输入是h_0和h_1做concat就行了,也就是两个节点当前的特征拼接成一个vector作为输入,然后通过linear变换,变成中间向量m,每个...

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...
