Entropy-Aware Time-Varying Graph Neural Networks with Generalized Temporal Hawkes Process: Dynamic Link Prediction in the Presence of Node Addition and Deletion

Bahareh Najafi, Saeedeh Parsaeefard, Alberto Leon-Garcia

This paper addresses the problem of learning temporal graph representations, which capture the changing nature of complex evolving networks. Existing approaches mainly focus on adding new nodes and edges to capture dynamic graph structures. However, to achieve more accurate repre…

Missing Data Estimation in Temporal Multilayer Position-Aware Graph Neural Network (TMP-GNN)

Bahareh Najafi, Saeedeh Parsaeefard, Alberto Leon-Garcia

GNNs have been proven to perform highly effectively in various node-level, edge-level, and graph-level prediction tasks in several domains. Existing approaches mainly focus on static graphs. However, many graphs change over time and their edge may disappear, or the node/edge attr…
