Community-Aware Graph Signal Processing
Miljan Petrovic, Raphael Liegeois, Thomas A. W. Bolton +1
The emerging field of graph signal processing (GSP) allows to transpose classical signal processing operations (e.g., filtering) to signals on graphs. The GSP framework is generall…
Guided Graph Spectral Embedding: Application to the C. elegans Connectome
Miljan Petrović, Thomas A. W. Bolton, Maria Giulia Preti +2
Graph spectral analysis can yield meaningful embeddings of graphs by providing insight into distributed features not directly accessible in nodal domain. Recent efforts in graph si…
Sparse plus low-rank autoregressive identification in neuroimaging time series
Raphaël Liégeois, Bamdev Mishra, Mattia Zorzi +1
This paper considers the problem of identifying multivariate autoregressive (AR) sparse plus low-rank graphical models. Based on the corresponding problem formulation recently pres…
Cerebral functional connectivity periodically (de)synchronizes with anatomical constraints
Raphaël Liégeois, Erik Ziegler, Pierre Geurts +7
This paper studies the link between resting-state functional connectivity (FC), measured by the correlations of the fMRI BOLD time courses, and structural connectivity (SC), estima…
