Community Detection from Multiple Observations: from Product Graph Model to Brain Applications

This paper proposes a multilayer graph model for community detection based on multiple observations. This scenario is common when different estimators are used to infer graph edges from signals at the nodes, or when various signal measurements are …

Improving J-divergence of brain connectivity states by graph Laplacian denoising

Functional connectivity (FC) can be represented as a network, and is frequently used to better understand the neural underpinnings of complex tasks such as motor imagery (MI) detection in brain-computer interfaces (BCIs). However, errors in the …
