摘要:

社交网络和信息网络由于其各种应用而最近获得了巨大的普及。通过节点和边形式的图进行的知识表示应尽可能多地保留原始数据的特征。这些图的一些有趣和有用的应用是图分类,节点分类,链接预测等图神经网络在过去的几年中已经发展。图神经网络(GNN)是深入了解大型动态图数据集的有效方法,这些数据集捕获数十亿实体之间的关系,也称为知识图谱。本文讨论了图卷积神经网络、图自编码器和时空图神经网络。可以使用这些方法学习图在较低维度中的表示。较低维度的表示可以进一步用于下游机器学习任务。

英文摘要:

Social and information networks are gaining huge popularity recently due to their various applications. Knowledge representation through graphs in the form of nodes and edges should preserve as many characteristics of the original data as possible. Some of the interesting and useful applications on these graphs are graph classification, node classification, link prediction, etc. The Graph Neural Networks have evolved over the last few years. Graph Neural Networks (GNNs) are efficient ways to get insight into large and dynamic graph datasets capturing relationships among billions of entities also known as knowledge graphs. In this paper, we discuss the graph convolutional neural networks graph autoencoders and spatio-temporal graph neural networks. The representations of the graph in lower dimensions can be learned using these methods. The representations in lower dimensions can be used further for downstream machine learning tasks.
