Node embedding for network community discovery
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017Neural node embedding has been recently developed as a powerful representation for supervised tasks with graph data. We leverage this recent advance and propose a novel approach for unsupervised community discovery in graphs. Through extensive experimental studies on simulated and real-world data, we demonstrate consistent improvement of the proposed ...

On minimal‐node‐cost planar embeddings
Networks, 1984AbstractThe problem of embedding an undirected graph on the planar grid is considered. Two common cost measures for this sort of problem are the area consumed by the embedding and the total length of edges in the embedding. This paper considers a third cost measure, called thenode cost measure, which is the total number of bends that are present along ...

Node Embeddings in Social Network Analysis
Proceedings of the 2015 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining 2015, 2015We introduce a distributed representation of nodes, node embeddings, in social network analysis. We compute embeddings for nodes based on their attributes and links. These embeddings can support many social network applications --- including analyses of community homogeneity, distance, and detection of community connectors (inter-community outliers ...

Matching Node Embeddings for Graph Similarity
Proceedings of the AAAI Conference on Artificial Intelligence, 2017Graph kernels have emerged as a powerful tool for graph comparison. Most existing graph kernels focus on local properties of graphs and ignore global structure. In this paper, we compare graphs based on their global properties as these are captured by the eigenvectors of their adjacency matrices.

Virtual network embedding by node-splitting
2013 15th IEEE International Conference on Communication Technology, 2013Network virtualization, as a fundamental technology of Future Internet Architecture, has been used to overcome the ossification of the current Internet. This paper focuses on virtual nodes splitting for aggregating the diverse physical resources in the issue of virtual network embedding (VNE), which is used for the resource allocation in network ...

Tensor Decomposition-based Node Embedding
Proceedings of the 28th ACM International Conference on Information and Knowledge Management, 2019In recent years, node embedding algorithms, which learn low dimensional vector representations for nodes in a graph, have been one of the key research interests of the graph mining community. The existing algorithms either rely on computationally expensive eigendecomposition of the large matrices, or require tuning of the word embedding-based ...

Learning Node Embeddings in Interaction Graphs
Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017Node embedding techniques have gained prominence since they produce continuous and low-dimensional features, which are effective for various tasks. Most existing approaches learn node embeddings by exploring the structure of networks and are mainly focused on static non-attributed graphs. However, many real-world applications, such as stock markets and

Learning Community Embedding with Community Detection and Node Embedding on Graphs
Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017In this paper, we study an important yet largely under-explored setting of graph embedding, i.e., embedding communities instead of each individual nodes. We find that community embedding is not only useful for community-level applications such as graph visualization, but also beneficial to both community detection and node classification. To learn such
