通常,反对意见函数需要多次迭代才能收敛。按照常用的程序得到由\frac{1}{2}(\left| S \right|+\left| S^{T} \right|)定义的非负对称矩阵C最后,将著名的光谱聚类算法应用于C,以获得最终的聚类结果。在下面Algorithm 1中概述了该算法的完整步骤。根据交替优化理论,目标函数将收敛。 3.实验分析 数据集选取:ACM...
又做了一次自表示学习,即每个样本可以表示为其他样本的线性组合形式,而这个组合系数矩阵表示了任意两个点之间的相似性,即要学习的相似性图矩阵。这种做法减轻了手工制作的相似度指标所带来的偏差(Robust graph learning from noisy data-2020)。该过程可以形式化为: 其中, 是trade-off系数, 是相似性图矩阵。第一项...
Graph Filter-based Multi-view Attributed Graph Clustering[C]//IJCAI. 2021: 2723-2729. 【背景】 本文主要做的的属性图的聚类问题,当前的针对于multi-view的图表示学习方法主要可以被分为两个类别: 将多视图的数据映射到一个图中,然后使用单视图的算法。 通过一些表示学习方法来获得节点embedding之后,然后使用...
This paper explores the potential of Optimal Transport (OT) to impute missing attributes on graphs. To proceed, we design a novel multi-view OT loss function that can encompass both node feature data and the underlying topological structure of the graph by utilizing multiple graph representations....

Although such strategy provides a new viewpoint to integrate topological structure and attribute information together, they can not interpret which attributes are relevant to the formation of clusters. In this paper, we propose a new attributed graph clustering algorithm based on subspace stochastic ...
