摘要:

社区发现算法用于检测复杂网络中的密集连接组件,并揭示组件之间的潜在关系。空间网络作为一种特殊的网络类型,通常是由地理区域之间的联系而产生的。识别空间网络社区有助于揭示空间互动模式,了解隐藏的区域结构,为区域发展决策提供支持。鉴于图卷积网络(GCN)的最新发展及其在识别多尺度空间交互方面的强大性能,提出了一种基于GCN的无监督空间网络社区发现方法“region2vec”.我们的方法首先为共享共同属性并具有强烈空间相互作用的区域生成节点嵌入,然后应用聚类算法根据其嵌入相似性和空间邻接性来检测社区。实验结果表明,虽然现有的方法权衡属性相似性或空间相互作用的另一个,“region2vec”保持了很大的平衡,两者之间,并执行最好的,当一个人想要最大限度地提高属性相似性和社区内的空间相互作用。

英文摘要:

Community Detection algorithms are used to detect densely connected components in complex networks and reveal underlying relationships among components. As a special type of networks, spatial networks are usually generated by the connections among geographic regions. Identifying the spatial network communities can help reveal the spatial interaction patterns, understand the hidden regional structures and support regional development decision-making. Given the recent development of Graph Convolutional Networks (GCN) and its powerful performance in identifying multi-scale spatial interactions, we proposed an unsupervised GCN-based community detection method "region2vec" on spatial networks. Our method first generates node embeddings for regions that share common attributes and have intense spatial interactions, and then applies clustering algorithms to detect communities based on their embedding similarity and spatial adjacency. Experimental results show that while existing methods trade off either attribute similarities or spatial interactions for one another, "region2vec" maintains a great balance between both and performs the best when one wants to maximize both attribute similarities and spatial interactions within communities.
