Fast Unsupervised Graph Embedding Based on Anchors [PDF]

open access: yesJisuanji kexue, 2022
Graph embedding is a widely used method for dimensionality reduction due to its computational effectiveness.The computational complexity of graph embedding method to construct traditional K-Nearest Neighbors (K-NN) graph is at least O(n2d), where n and d

Link-Privacy Preserving Graph Embedding Data Publication with Adversarial Learning

open access: yesTsinghua Science and Technology, 2022
The inefficient utilization of ubiquitous graph data with combinatorial structures necessitates graph embedding methods, aiming at learning a continuous vector space for the graph, which is amenable to be adopted in traditional machine learning ...

Embedding Graphs into Embedded Graphs [PDF]

open access: yesAlgorithmica, 2020
A (possibly denerate) drawing of a graph $G$ in the plane is approximable by an embedding if it can be turned into an embedding by an arbitrarily small perturbation. We show that testing, whether a straight-line drawing of a planar graph $G$ in the plane is approximable by an embedding, can be carried out in polynomial time, if a desired embedding of ...

Embedding a Forest in a Graph [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
For $p\ge 1$, we prove that every forest with $p$ trees whose sizes are $a_1, \ldots, a_p$ can be embedded in any graph containing at least $\sum_{i=1}^p (a_i + 1)$ vertices and having minimum degree at least $\sum_{i=1}^p a_i$.

Graph Space Embedding [PDF]

open access: yesProceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence, 2019
We propose the Graph Space Embedding (GSE), a technique that maps the input into a space where interactions are implicitly encoded, with little computations required. We provide theoretical results on an optimal regime for the GSE, namely a feasibility region for its parameters, and demonstrate the experimental relevance of our findings.

SAGES: Scalable Attributed Graph Embedding With Sampling for Unsupervised Learning [PDF]

open access: yes, 2023
Unsupervised graph embedding method generates node embeddings to preserve structural and content features in a graph without human labeling burden. However, most unsupervised graph representation learning methods suffer issues like poor scalability or ...

On Embeddings of Circulant Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
A circulant of order $n$ is a Cayley graph for the cyclic group $\mathbb{Z}_n$, and as such, admits a transitive action of $\mathbb{Z}_n$ on its vertices. This paper concerns 2-cell embeddings of connected circulants on closed orientable surfaces.

GAE-Based Document Embedding Method for Clustering

open access: yesIEEE Access, 2022
Document embedding methods for clustering using deep neural networks have been proposed recently. However, the existing deep neural network-based document embedding methods for clustering have a problem of either generating document embeddings dependent ...

Joint Embedding of Graphs [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2021
Feature extraction and dimension reduction for networks is critical in a wide variety of domains. Efficiently and accurately learning features for multiple graphs has important applications in statistical inference on graphs. We propose a method to jointly embed multiple undirected graphs.
