Shared Nodes of Overlapping Communities in Complex Networks
Vesa Kuikka, Kosti Koistinen, Kimmo K Kaski
Overlapping communities are key characteristics of the structure and function analysis of complex networks. Shared or overlapping nodes within overlapping communities can form eith…
Network Centrality Metrics Based on Unrestricted Paths, Walks and Cycles Compared to Standard Centrality Metrics
Juuso Luhtala, Vesa Kuikka, Kimmo K. Kaski
Traditional measures of closeness and betweenness centrality in networks rely on the shortest paths between nodes. Many standard metrics fail to accurately reflect the physical or…
Importance of Overlapping Network Nodes in Influence Spreading
Kosti Koistinen, Vesa Kuikka, Kimmo Kaski
In complex networks there are overlapping substructures or "circles" that consist of nodes belonging to multiple cohesive subgroups. Yet the role of these overlapping nodes in infl…
Temporal social network modeling of mobile connectivity data with graph neural networks
Joel Jaskari, Chandreyee Roy, Fumiko Ogushi +3
Graph neural networks (GNNs) have emerged as a state-of-the-art data-driven tool for modeling connectivity data of graph-structured complex networks and integrating information of…
Integrating Network and Attack Graphs for Service-Centric Impact Analysis
Joni Herttuainen, Vesa Kuikka, Kimmo K. Kaski
Cyberattacks on enterprise networks exploit complex dependencies among infrastructure, services, and applications, which challenge traditional analysis methods that focus on attack…
