Exploring the Performance of Continuous-Time Dynamic Link Prediction Algorithms

1 code implementation27 May 2024 Raphaël Romero, Maarten Buyl, Tijl De Bie, Jefrey Lijffijt

However, a single metric is not sufficient to fully capture the differences between DLP algorithms, and is prone to overly optimistic performance evaluation.

Gaussian Embedding of Temporal Networks

1 code implementation27 May 2024 Raphaël Romero, Jefrey Lijffijt, Riccardo Rastelli, Marco Corneli, Tijl De Bie

Representing the nodes of continuous-time temporal graphs in a low-dimensional latent space has wide-ranging applications, from prediction to visualization.

New Perspectives on the Evaluation of Link Prediction Algorithms for Dynamic Graphs

1 code implementation30 Nov 2023 Raphaël Romero, Tijl De Bie, Jefrey Lijffijt

We leverage these visualization tools to investigate the effect of negative sampling on the predictive performance, at the node and edge level.
