Towards Deeper Graph Neural Networks 问题: 一层的GCN layer只考虑直接邻域,加深模型层数可获得更大的感受野receptive fields,但性能却会变坏。 以前认为是over-smoothing问题导致的。 本文 增加层性能变坏是因为GCN模型里两个关键部分——representation transformation和propagation——的纠缠导致的。 分离这两个部分......

Introduction to GraphNeural Networks 笔记1 1.1. introduction 1.1.1 CONVOLUTIONAL NEURAL NETWORKS GNN受到CNN启发,CNN的关键点:局部连接,共享参数,多层。图领域解决这些问题也很重要: 1.图有最传统的局部连接结构 2.共享参数比传统的谱图理论减少参数 3.多层结构是处理层级模式的关键,能够捕捉不同尺寸的特征。 1....
三Graph Neural Networks 构建一个GNN,查看各个模块构成 > GNN是什么呢? GNN,是一个对图上所以的属性,包括顶点、边、全局的上下文,进行的一个可以优化的变换,这个变换,是能够保持住图的对称信息的(对称信息:我把这些顶点进行另外一个排序之后,整个结果是不会变的)。 接下来使用一个叫做“message passing neur...
5.Graph Neural Networks 在经历了将数据转为graph以及将graph进行表示后,我们就能使用GNN来对图进行处理了。 一句话概括GNN:GNN是对图的所有属性(节点、边、全局上下文)进行的可优化的一种变换,它保留了图的对称性(置换不变性)。 简单来说就是,我们初始给定了节点或者边或者全局的属性,GNN将对这些属性进行变换,...
. Graph neural networks (GNNs) are proposed to combine the feature information and the graph structure to learn better representations on graphs via feature propagation and aggregation. Due to its convincing performance and high interpretability, GNN has recently become a widely applied graph analysis ...
