Extracting Interpretable Higher-Order Topological Features across Multiple Scales for Alzheimer's Disease Classification Open
Brain network topology, derived from functional magnetic resonance imaging (fMRI), holds promise for improving Alzheimer's disease (AD) diagnosis. Current methods primarily focus on lower-order topological features, often overlooking the s…

HOI-Brain: a novel multi-channel transformers framework for brain disorder diagnosis by accurately extracting signed higher-order interactions from fMRI Open
Accurately characterizing higher-order interactions of brain regions and extracting interpretable organizational patterns from Functional Magnetic Resonance Imaging data is crucial for brain disease diagnosis. Current graph-based deep lear…

An Independent Cascade Model of Graph Burning Open
Graph burning was introduced to simulate the spreading of news/information/rumors in social networks. The symmetric undirected graph is considered here. That is, vertex u can spread the information to vertex v, and symmetrically vertex v c…

Dismantling networks abruptly by tree decomposition Open
Dismantling a network by removing the minimum vertices is a challenging problem in complex networks. While most existing methods focus on efficiency, they overlook the importance of abruptness during the dismantling process. Gradual change…

Spreading to Localized Targets in Signed Social Networks Open
Inspired by lots of applications like viral marketing of products and transmitting information in a network, ranking the spreading ability of nodes in the network has been widely studied. At present, the above problem is mostly studied on …
