Graph Embedding Matrix Sharing With Differential Privacy

open access: yesIEEE Access, 2019
Graph embedding maps a graph into low-dimensional vectors, i.e., embedding matrix, while preserving the graph structure, solving the high computation and space cost for graph analysis.

A Toroidal Maxwell–Cremona–Delaunay Correspondence

open access: yesJournal of Computational Geometry, 2022
We consider three classes of geodesic embeddings of graphs on Euclidean flat tori: • A toroidal graph embedding Γ is positive equilibrium if it is possible to place positive weights on the edges, such that the weighted edge vectors incident to each ...

Improved Skip-Gram Based on Graph Structure Information

open access: yesSensors, 2023
Applying the Skip-gram to graph representation learning has become a widely researched topic in recent years. Prior works usually focus on the migration application of the Skip-gram model, while Skip-gram in graph representation learning, initially ...

Nonlinear Dynamic Field Embedding: On Hyperspectral Scene Visualization [PDF]

open access: yes, 2012
In many areas of research, complex signals are commonly represented by high dimensional feature vectors. However, high dimensional vectors are difficult to analyze and interpret due to the curse of dimensionality.

Uniform graph embedding into metric spaces [PDF]

open access: yesКомпьютерные исследования и моделирование, 2012
The task of embedding an infinity countable graph into continuous metric space is considered. The concept of uniform embedding having no accumulation point in a set of vertex images and having all graph edge images of a limited length is introduced ...

Embedding Graphs into Two-Dimensional Simplicial Complexes

open access: yesComputing in Geometry and Topology, 2022
We consider the problem of deciding whether an input graph G admits a topological embedding into an input two-dimensional simplicial complex C. This problem includes, among others, the embeddability problem of a graph on a surface and the topological ...

Extremal embedded graphs

open access: yesArs Mathematica Contemporanea, 2019
Summary: Let \(G\) be a ribbon graph and \(\mu (G)\) be the number of components of the virtual link formed from \(G\) as a cellularly embedded graph via the medial construction. In this paper we first prove that \(\mu (G) \leq f(G) + \gamma (G)\), where \(f(G)\) and \(\gamma (G)\) are the number of boundary components and Euler genus of \(G ...

Distance measures for embedded graphs [PDF]

open access: yesComputational Geometry, 2021
We introduce new distance measures for comparing straight-line embedded graphs based on the Fréchet distance and the weak Fréchet distance. These graph distances are defined using continuous mappings and thus take the combinatorial structure as well as the geometric embeddings of the graphs into account.
