Graph sampling for node embedding

open access: yesCoRR, 2022
Node embedding is a central topic in graph representation learning. Computational efficiency and scalability can be challenging to any method that requires full-graph operations. We propose sampling approaches to node embedding, with or without explicit modelling of the feature vector, which aim to extract useful information from both the eigenvectors ...

Weighted Spectral Embedding of Graphs [PDF]

open access: yes, 2018
We present a novel spectral embedding of graphs that incorporates weights assigned to the nodes, quantifying their relative importance. This spectral embedding is based on the first eigenvectors of some properly normalized version of the Laplacian.

A Node Embedding-Based Influential Spreaders Identification Approach

open access: yesMathematics, 2020
Node embedding is a representation learning technique that maps network nodes into lower-dimensional vector space. Embedding nodes into vector space can benefit network analysis tasks, such as community detection, link prediction, and influential node ...

Virtual Network Embedding Based on Topology Potential

open access: yesEntropy, 2018
To improve the low acceptance ratio and revenue to cost ratio caused by the poor match between the virtual nodes and the physical nodes in the existing virtual network embedding (VNE) algorithms, we established a multi-objective optimization integer ...

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 ...

Embedding cube-connected cycles graphs into faulty hypercubes [PDF]

open access: yes, 1994
We consider the problem of embedding a cube-connected cycles graph (CCC) into a hypercube with edge faults. Our main result is an algorithm that, given a list of faulty edges, computes an embedding of the CCC that spans all of the nodes and avoids all of

div2vec: Diversity-Emphasized Node Embedding [PDF]

open access: yesCoRR, 2020
Recently, the interest of graph representation learning has been rapidly increasing in recommender systems. However, most existing studies have focused on improving accuracy, but in real-world systems, the recommendation diversity should be considered as well to improve user experiences. In this paper, we propose the diversity-emphasized node embedding

On distributed virtual network embedding with guarantees [PDF]

open access: yes, 2016
To provide wide-area network services, resources from different infrastructure providers are needed. Leveraging the consensus-based resource allocation literature, we propose a general distributed auction mechanism for the (NP-hard) virtual network (VNET)

ALPINE : Active Link Prediction using Network Embedding [PDF]

open access: yes, 2020
Many real-world problems can be formalized as predicting links in a partially observed network. Examples include Facebook friendship suggestions, consumer-product recommendations, and the identification of hidden interactions between actors in a crime ...

Enhancing Attributed Network Embedding via Similarity Measure

open access: yesIEEE Access, 2019
Network embedding aims to represent network structural and attributed information with low-dimensional vectors, which has been demonstrated to be beneficial for many network analysis tasks, such as link prediction, node classification and visualization ...
