Diffusion-Induced Spatial Attention Overlapping Community Detection
Kosti Koistinen, Vesa Kuikka, Joni Herttuainen +3
Detection of overlapping communities is essential for modelling networks in which nodes participate simultaneously in multiple structural or functional groups. Existing graph neura…
Spatio-Temporal Attention Graph Neural Network: Explaining Causalities With Attention
Kosti Koistinen, Kirsi Hellsten, Joni Herttuainen +1
Industrial Control Systems (ICS) underpin critical infrastructure and face growing cyber-physical threats due to the convergence of operational technology and networked environment…
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…
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…
