A Survey on Embedding Dynamic Graphs

no code implementations4 Jan 2021 Claudio D. T. Barros, Matheus R. F. Mendonça, Alex B. Vieira, Artur Ziviani

Embedding static graphs in low-dimensional vector spaces plays a key role in network analytics and inference, supporting applications like node classification, link prediction, and graph visualization.

Efficient Information Diffusion in Time-Varying Graphs through Deep Reinforcement Learning

1 code implementation27 Nov 2020 Matheus R. F. Mendonça, André M. S. Barreto, Artur Ziviani

In this context, we propose Spatio-Temporal Influence Maximization~(STIM), a model trained with Reinforcement Learning and Graph Embedding over a set of artificial TVGs that is capable of learning the temporal behavior and connectivity pattern of each node, allowing it to predict the best moment to start a diffusion through the TVG.

Approximating Network Centrality Measures Using Node Embedding and Machine Learning

1 code implementation29 Jun 2020 Matheus R. F. Mendonça, André M. S. Barreto, Artur Ziviani

Our proposed model, entitled Network Centrality Approximation using Graph Embedding (NCA-GE), uses the adjacency matrix of a graph and a set of features for each node (here, we use only the degree) as input and computes the approximate desired centrality rank for every node.
