New Perspectives on the Evaluation of Link Prediction Algorithms for Dynamic Graphs
Raphaël Romero, Tijl De Bie, Jefrey Lijffijt
There is a fast-growing body of research on predicting future links in dynamic networks, with many new algorithms. Some benchmark data exists, and performance evaluations commonly…
Adversarial Robustness of Probabilistic Network Embedding for Link Prediction
Xi Chen, Bo Kang, Jefrey Lijffijt +1
In today's networked society, many real-world problems can be formalized as predicting links in networks, such as Facebook friendship suggestions, e-commerce recommendations, and t…
CSNE: Conditional Signed Network Embedding
Alexandru Mara, Yoosof Mashayekhi, Jefrey Lijffijt +1
Signed networks are mathematical structures that encode positive and negative relations between entities such as friend/foe or trust/distrust. Recently, several papers studied the…
Explainable Subgraphs with Surprising Densities: A Subgroup Discovery Approach
Junning Deng, Bo Kang, Jefrey Lijffijt +1
The connectivity structure of graphs is typically related to the attributes of the nodes. In social networks for example, the probability of a friendship between two people depends…
Mining Subjectively Interesting Attributed Subgraphs
Anes Bendimerad, Ahmad Mel, Jefrey Lijffijt +3
Community detection in graphs, data clustering, and local pattern mining are three mature fields of data mining and machine learning. In recent years, attributed subgraph mining is…
Opinion Dynamics with Backfire Effect and Biased Assimilation
Xi Chen, Panayiotis Tsaparas, Jefrey Lijffijt +1
The democratization of AI tools for content generation, combined with unrestricted access to mass media for all (e.g. through microblogging and social media), makes it increasingly…
