摘要:

图嵌入技术近年来取得了重大进展。然而,目前的技术是不够有效的捕捉网络的模式。本文提出了neighbor 2 vec,一个基于邻居的采样策略,用于学习算法的邻域表示的节点,一个框架,收集结构信息的特征传播之间的节点和它的邻居。我们认为,neighbor 2 vec是一种简单有效的方法来提高图嵌入的可扩展性和平等性,它打破了现有的最先进的无监督技术的限制。我们对ogbn-arxiv、ogbn-products、ogbn-proteins、ogbl-ppa、ogbl-collab和ogbl-citation 2等网络的几个节点分类和链接预测任务进行了实验。结果表明,Neighbor 2 vec的表示在节点分类任务中提供的平均准确率比竞争方法高出6.8%,在链接预测任务中高出3.0%。在所有六个实验中,neighbor 2 vec的表示能够优于所有基线方法和两个经典的GNN模型。

英文摘要:

Graph embedding techniques have led to significant progress in recent years. However, present techniques are not effective enough to capture the patterns of networks. This paper propose neighbor2vec, a neighbor-based sampling strategy used algorithm to learn the neighborhood representations of node, a framework to gather the structure information by feature propagation between the node and its neighbors. We claim that neighbor2vec is a simple and effective approach to enhancing the scalability as well as equality of graph embedding, and it breaks the limits of the existing state-of-the-art unsupervised techniques. We conduct experiments on several node classification and link prediction tasks for networks such as ogbn-arxiv, ogbn-products, ogbn-proteins, ogbl-ppa,ogbl-collab and ogbl-citation2. The result shows that Neighbor2vec's representations provide an average accuracy scores up to 6.8 percent higher than competing methods in node classification tasks and 3.0 percent higher in link prediction tasks. The neighbor2vec's representations are able to outperform all baseline methods and two classical GNN models in all six experiments.
