图神经网络(Graph Neural Network,简称GNN)是一种用于处理图结构数据的深度学习模型。它通过学习节点之间的关系和图的拓扑结构来进行节点分类、图分类和链接预测等任务。原理基于消息传递和节点更新的思想,每个节点将周围节点的信息进行聚合和传递,以更新自身的表征向量。具体来说,图神经网络通过定义节点聚合函数和更新函数...
初始化数据集很简单。数据集的初始化将自动下载其原始文件，并将其处理为上文描述的Data格式。 如加载ENZYMES数据集（由6个类中的600个图组成）：from torch_geometric.datasets import TUDatasetdataset = TUDataset(root='/tmp/ENZYMES', name='ENZYMES')>>> ENZYMES(600)len(dataset)>>> 600dataset.num_classe...
Many real-world datasets have an underlying dynamic graph structure, where entities and their interactions evolve over time. Machine learning models should consider these dynamics in order to harness their full potential in downstream tasks. Previous approaches for graph representation learning have focused...

Most neural networks can go deep to obtain better performance, whereas GNNs are shallow networks mostly with three layers. It limits us from achieving state-of-the-art performance on large datasets. The graph structures are constantly changing, making it harder to train a model on it. Deployin...
Those who use graph databases know they’re growing in some cases to have thousands of features embedded on a single node or edge. That presents challenges of efficiently loading the massive datasets from storage subsystems through networks to processors. ...
