在前面的章节中,我们讨论了学习graph中节点的 low-dimensional embeddings 的方法,我们使用 shallow embedding 方法来生成节点的representations,shallow embedding方法简单地优化每个节点的embedding vector。 下面,我们将讨论更复杂的encoder models——图神经网络(GNN),GNN的主要思想是我们希望生成 基于图的结构以及节点特征...
Deep Neural Networks for Graph Representations (DNGR) Structural Deep Network Embedding (SDNE) Deep Recursive Network Embedding (DRNE) DNGR和SDNE学习仅给出拓扑结构的节点嵌入,而GAE、ARGA、NetRA、DRNE用于学习当拓扑信息和节点内容特征都存在时的节点嵌入。图自动编码器的一个挑战是邻接矩阵A的稀疏性,这使得...

Here we assess the applicability of graph neural networks (GNNs) for predicting the grain-scale elastic response of polycrystalline metallic alloys. Using GNN surrogate models, grain-averaged stresses during uniaxial elastic tension in low solvus high-re
Graph Neural Network(GNN)综述 导言 图(graph)是一个非常常用的数据结构,现实世界中很多很多任务可以描述为图问题,比如社交网络,蛋白体结构,交通路网数据,以及很火的知识图谱等,甚至规则网格结构数据(如图像,视频等)也是图数据的一种特殊形式,因此图是一个很值得研究的领域。
The main distinction between GNNs and network embedding GNNs和网络嵌入的主要区别 The main distinction between GNNs and network embedding is that GNNs are a group of neural network models which aredesigned for various tasks while network embedding coversvarious kinds of methods targeting the same task...
