Graph Neural Networks (GNNs) 对图结构数据$G = (V, E)$进行操作,迭代更新层$t-1$中节点$v∈V$的节点特征$\vec h_v^{(t−1)}$方法是通过一个由权值$Θ^{(t)}$参数化的可微函数$f^{(t)}Θ$从邻居集$N(·)$聚合本地化信息。在当前的实现中,$C^{(t−1)}{v,w}$要么被定义为静态结...
In this paper, with the help of graph neural networks, we further investigate the problem of efficient learning transferable policies for robots with serial structure, which commonly appears in various robot bodies, such as robotic arms and the leg of centipede. Based on a kinematics analysis on...
当然AGG也可以有很多变体,不一定非要是aggregate,也可以是pool,lstm等等。 4.Gated Graph Neural Networks[10]:go deeper with RNN GCNs and GraphSAGE generally only2-3 layersdeep,因此对于每个node所构成的aggregate图比较浅,如何走得更深呢? 可能会存在overfit或者梯度消失/爆炸,所以我们希望一个简化可重用的模...

Deep Graph Neural Networks with Shallow Subgraph Samplers,这篇文章使用浅子图采样器进行大图训练,主要针对深图神经网络的计算爆炸问题; Cluster-GCN: An Efficient Algorithm for Training Deep and Large Graph Convolutional Network,提出一种新的图神经网络的训练方法,它利用图聚类结构进行数据集采样。即本次学习的...
Graph data are pervasive in many real-world applications. Recently, increasing attention has been paid on graph neural networks (GNNs), which aim to model the local graph structures and capture the hierarchical patterns by aggregating the information from neighbors with stackable network modules. Motiv...

This is especially true considering the wide spread of rumors on popular social networks such as Twitter. Various kinds of techniques have been proposed for automatic rumor detection. In this work, we study the application of graph neural networks for rumor classification at a lower level, instead...
