Discrete embedding for attributed graphs
Pattern Recognition, 2022 Abstract Attributed graphs refer to graphs where both node links and node attributes are observable for analysis. Attributed graph embedding enables joint representation learning of node links and node attributes. Different from classical graph embedding methods such as Deepwalk and node2vec that first project node links into low-dimensional vectors ...

Exploring the space of graphs with fixed discrete curvatures [PDF]
Journal of Physics: ComplexityDiscrete curvatures are quantities associated to the nodes and edges of a graph that reflect the local geometry around them. These curvatures have a rich mathematical theory and they have recently found success as a tool to analyze networks across a wide

On the Discrete Fréchet Distance in a Graph [PDF]
CoRR, 2022 The Fréchet distance is a well-studied similarity measure between curves that is widely used throughout computer science. Motivated by applications where curves stem from paths and walks on an underlying graph (such as a road network), we define and study the Fréchet distance for paths and walks on graphs.

Cauchy problem for integrable discrete equations on quad-graphs [PDF]
, 2003 Initial value problems for the integrable discrete equations on quadgraphs are investigated. We give a geometric criterion of when such a problem is well-posed.

Domination in discrete topology graph [PDF]
AIP Conference Proceedings, 2019 In this paper a graph of the discrete topology under some conditions has been created. It is obtained from the composition of the topologies. The properties and domination number on the discrete topology graph have studied. On a modified graph through deleting or adding the vertex, the affection discrete topological graph domination parameter is ...

Graph-based methods for discrete choice
Network Science, 2023 AbstractChoices made by individuals have widespread impacts—for instance, people choose between political candidates to vote for, between social media posts to share, and between brands to purchase—moreover, data on these choices are increasingly abundant.

Discrete realizations of contact and intersection graphs.
, 1998 Summary: Known realizations of geometric representations of graphs, like contact, intersection, etc., are ``continuous'', in the sense that the geometric objects are drawn in Euclidean space with real numbers as coordinates. We initiate the study of dicrete versions of contact and intersection graphs and examine their relation to their continuous ...

Discrete linear canonical transform on graphs
Digital Signal Processing, 2023 With the wide application of spectral and algebraic theory in discrete signal processing techniques in the field of graph signal processing, an increasing number of signal processing methods have been proposed, such as the graph Fourier transform, graph wavelet transform and windowed graph Fourier transform.
