在本节中,我们将介绍在《Machine Learning on Graphs: A Model and Comprehensive Taxonomy》https://arxiv.org/abs/2005.03675中定义的分类法的简化版本。 在这种形式表示中,每个图、节点或边缘嵌入方法都可以由两个基本组件来描述,即编码器和解码器。编码器(encoder,ENC)将输入映射到嵌入空间,而解码器(decoder,DE...
2.3 图形注意力模型(Graph Attention Model ,GAM) 图形注意力模型(GAM)提供了一个循环神经网络模型,以解决图形分类问题,通过自适应地访问一个重要节点的序列来处理图的信息。GAM模型被定义为 h_{t} = f_{h}(f_{s}(r_{t-1}, v_{t-1}, g;\theta_{s}),h_{t-1};\theta_{h}) \\ 其中f_{h...

been trained for 200 epochs with a learning rate of 0.01, a weight decay factor of 0.005, a momentum of 0.9 and a dropout rate of 0.2. The performance of the model is assessed by training the readout layer upon different randomly initialized weights (ten sets of weights were used here)....
Model training. Machine learning models can be trained using knowledge graphs, especially in graph-native learning methods. By calculating machine learning problems inside of a graph structure, a process known as graph-native learning, models can learn generalized, predictive properties directly from the...
