Decoupling of brain function from structure reveals regional behavioral specialization in humans
Maria Giulia Preti, Dimitri Van De Ville
The brain is an assembly of neuronal populations interconnected by structural pathways. Brain activity is expressed on and constrained by this substrate. Therefore, statistical dep…
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…
Augmented Slepians: Bandlimited Functions that Counterbalance Energy in Selected Intervals
Robin Demesmaeker, Maria Giulia Preti, Dimitri Van De Ville
Slepian functions provide a solution to the optimization problem of joint time-frequency localization. Here, this concept is extended by using a generalized optimization criterion…
Guiding Network Analysis using Graph Slepians: An Illustration for the C. Elegans Connectome
Dimitri Van De Ville, Robin Demesmaeker, Maria Giulia Preti
Spectral approaches of network analysis heavily rely upon the eigendecomposition of the graph Laplacian. For instance, in graph signal processing, the Laplacian eigendecomposition…
When Slepian Meets Fiedler: Putting a Focus on the Graph Spectrum
Dimitri Van De Ville, Robin Demesmaeker, Maria Giulia Preti
The study of complex systems benefits from graph models and their analysis. In particular, the eigendecomposition of the graph Laplacian lets emerge properties of global organizati…
