Towards Interpretation of Node Embeddings [PDF]

open access: yesCompanion of the The Web Conference 2018 on The Web Conference 2018 - WWW '18, 2018
Recently there have been a large number of studies on embedding large-scale information networks using low-dimensional, neighborhood and community aware node representations. Though the performance of these embedding models have been better than traditional methods for graph mining applications, little is known about what these representations encode ...

The Effects of Randomness on the Stability of Node Embeddings [PDF]

open access: yes, 2021
We systematically evaluate the (in-)stability of state-of-the-art node embedding algorithms due to randomness, i.e., the random variation of their outcomes given identical algorithms and graphs. We apply five node embeddings algorithms---HOPE, LINE, node2vec, SDNE, and GraphSAGE---to synthetic and empirical graphs and assess their stability under ...

Effective attributed network embedding with information behavior extraction [PDF]

open access: yesPeerJ Computer Science, 2022
Network embedding has shown its effectiveness in many tasks, such as link prediction, node classification, and community detection. Most attributed network embedding methods consider topological features and attribute features to obtain a node embedding ...

Semisupervised Community Preserving Network Embedding with Pairwise Constraints

open access: yesComplexity, 2020
Network embedding aims to learn the low-dimensional representations of nodes in networks. It preserves the structure and internal attributes of the networks while representing nodes as low-dimensional dense real-valued vectors.

The node importance evaluation method based on graph convolution in multilayer heterogeneous networks

open access: yesConnection Science, 2023
Node importance evaluation is a hot issue in complex network analysis. Existing node importance evaluation methods are mainly oriented to homogeneous networks, which ignore the heterogeneity of node types and edges.

Kernel Node Embeddings

open access: yes2019 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2019
Learning representations of nodes in a low dimensional space is a crucial task with many interesting applications in network analysis, including link prediction and node classification. Two popular approaches for this problem include matrix factorization and random walk-based models.

A Systematic Evaluation of Node Embedding Robustness

open access: yesCoRR, 2022
Node embedding methods map network nodes to low dimensional vectors that can be subsequently used in a variety of downstream prediction tasks. The popularity of these methods has grown significantly in recent years, yet, their robustness to perturbations of the input data is still poorly understood.

Multiplex Network Embedding Model with High-Order Node Dependence

open access: yesComplexity, 2021
Multiplex networks have been widely used in information diffusion, social networks, transport, and biology multiomics. They contain multiple types of relations between nodes, in which each type of the relation is intuitively modeled as one layer.
