给定一个空间图和一组节点属性,节点属性空间图分区 (NSGP) 问题将节点属性空间图划分为 k 个同质子图,在满足子图大小约束的同时,最小化总 RMSErank1 和边切割。 RMSErank1 是矩阵与其一阶分解之间的均方根误差。 NSGP 问题对于许多社会应用都很重要,例如识别空间图中的同质社区和检测交通事故中的相互关联模式。这个问题是NP困难的;由于空间图的尺寸很大并且子图必须是同质的,即在节点属性方面相似,因此在计算上具有挑战性。本文提出了一种寻找一组同质子图的新方法,该方法可以在满足大小约束的同时最小化总 RMSErank1 和边缘切割。使用美国人口普查数据集和 HP#6 分水岭网络数据集的实验和案例研究表明,所提出的方法将空间图划分为一组同构子图,并降低了计算成本。
Given a spatial graph and a set of node attributes, the Node-attributed Spatial Graph Partitioning (NSGP) problem partitions a node-attributed spatial graph into k homogeneous sub-graphs that minimize both the total RMSErank1 and edge-cuts while meeting a size constraint on the sub-graphs. RMSErank1 is the Root Mean Square Error between a matrix and its rank-one decomposition. The NSGP problem is important for many societal applications such as identifying homogeneous communities in a spatial graph and detecting interrelated patterns in traffic accidents. This problem is NP-hard; it is computationally challenging because of the large size of spatial graphs and the constraint that the sub-graphs must be homogeneous, i.e. similar in terms of node attributes. This paper proposes a novel approach for finding a set of homogeneous sub-graphs that can minimize both the total RMSErank1 and edge-cuts while meeting the size constraint. Experiments and a case study using U.S. Census datasets and HP#6 watershed network datasets demonstrate that the proposed approach partitions a spatial graph into a set of homogeneous sub-graphs and reduces the computational cost.
