The strategy for node and network robust based on graph coloring theory and diversity is introduced first, the graph derived from the algorithm with 35 nodes and 4 coloring plan is analyzed in detail; 4 kinds of benchmark network that usually using are also used for contrastive analyze to the...
ROOF CONTOURS RECOGNITION USING LIDAR DATA AND MARKOV RANDOM FIELD MODEL ON GRAPH THEORY Building roof contour extraction methodologies is of fundamental importance in the context of spatial data capture and updating for GIS (Geographic Information Systems) applications. In this paper, a methodology is...
An important operation that is often performed in the course of graph analysis is node clustering. Popular methods for node clustering such as the normalized cut method have their roots in graph partition optimization and spectral graph theory. Recently, there has been increasing interest in modeling...
In this paper, we propose graph attention based network representation (GANR) which utilizes the graph attention architecture and takes graph structure as the supervised learning information. Compared with node classification based representations, GANR can be used to learn representation for any given ...
(2) are the left and right singular vectors of a certain matrix, in this caseB, and the matrix Perron–Frobenius theory tells us that if the bipartite graph with adjacency matrix\(\left(\begin{array}{ll}0&B\\ {B}^{\top }&0\end{array}\right)\)is connected, then Eq. (2) has ...
In this paper, we provide a theory of using graph neural networks (GNNs) for multi-node representation learning (where we are interested in learning a representation for a set of more than one node, such as link). We know that GNN is designed to learn single-node representations. When we...
Given a node-weighted convex bipartite graph G =( X, Y, E ) (where Y is linearly ordered and the neighborhood of each node of X is an interval of Y ), we show that it is possible to find an X -perfect matching of maximum (or minimum) weight in O (| E | + | Y | log |...

With the ongoing advancements in deep learning technology research, an increasing number of studies have emerged that focus on applying deep learning techniques for dynamic network link prediction. Xian et al.15proposed a link prediction model, GraphLP, based on network reconstruction theory, which le...
This paper proposes a kind of network typology connectivity analysis algorithm——node connective island combination method based on the graph theory. The multidimensional array data structure which the method adopts can not only completely reflect the information of the network's topology, but also sto...
