Goyal P, Chhetri SR, Canedo A. dyngraph2vec: Capturing network dynamics using dynamic graph representation learning. arXiv preprint arXiv:180902657. 2018. Previous methods on graph representation learning mainly focus on static graphs, however, many real-world graphs are dynamic and evolve over time. In this paper, we present Dynamic Self-Attention Network (DySAT), a novel neural architecture that operates on dynamic graphs and learns node representations that capture both structural properties and temporal evolutionary patterns.

More precisely, we focus on reviewing techniques that either produce time-dependent embeddings that capture the essence of the nodes and edges of evolving graphs or use embed- In this survey, we review the recent advances in representation learning for dynamic graphs, including dynamic knowledge graphs. We describe existing models from an encoder-decoder perspective, categorize these encoders and decoders based on the techniques they employ, and analyze the approaches in each category. Representation Learning for Dynamic Graphs: A Survey . Seyed Mehran Kazemi, Rishab Goel, Kshitij Jain, Ivan Kobyzev, Akshay Sethi, Peter Forsyth, Pascal Poupart; 21(70):1−73, 2020. Abstract. Graphs arise naturally in many real-world applications including social networks, recommender systems, ontologies, biology, and computational finance.

In this survey, we review the recent advances in representation learning for dynamic graphs, including dynamic knowledge graphs.

The sub-area of graph representation has reached a certain maturity, with multiple reviews, workshops and papers at top AI/ML venues. Deep learning needs to move beyond vector, fixed-size data. Learning representation as a powerful way to discover hidden Abstract: Learning latent representations of nodes in graphs is an important and ubiquitous task with widespread applications such as link prediction, node classification, and graph visualization. Previous methods on graph representation learning mainly focus on static graphs, however, many real-world graphs are dynamic and evolve over time.

They benefit from leveraging program structure like control flow graphs, but they are not well-suited to tasks like program execution that require far more sequential reasoning steps than number of GNN Acknowledging the dynamic nature of knowledge graphs, the problem of learning temporal knowledge graph embeddings has recently gained attention. Essentially, the goal is to learn vector representation for the nodes and edges of a knowledge graph taking time into account. An important part of many machine learning workflows on graphs is vertex representation learning, i.e., learning a low-dimensional vector representation for each vertex in the graph.
