[Dip. Scienze Statistiche - Mi]

Il Dipartimento di Scienze Statistiche dell'Università Cattolica del Sacro Cuore ha organizzato un seminario, presentato dal Dott. Daniele DURANTE, Università degli Studi di Padova, dal titolo:



Bayesian nonparametric modeling of network data



Giovedì 18 Febbraio dalle ore 15,00

in Aula G 052



Università Cattolica del Sacro Cuore - Milano

Largo Gemelli,1 - Edificio Lanzone 18

Abstract:

In neuroscience there is increasing interest in relating the structural connection network in white matter tracts (fibers) in the human brain and cognitive traits and neuropsychiatric disorders.  There is evidence that the structural network is a more important driver of variability in cognitive traits and disorders than measures of human brain activity (e.g., extracted from fMRI).  Recent connectomics pipelines can estimate the brain network based on diffusion tensor imaging and structural MRI.

This produces a network-valued random variable for each individual in a study.  We develop novel nonparametric Bayes methods for analyzing network-valued data, and for performing inference on the relationship between brain networks and cognitive traits.  These methods are provably flexible, reduce dimension adaptively and can be used for formal inferences on group differences adjusting for multiple comparisons automatically.  We show dramatic improvements relative to current approaches and illustrate the methods through application to creative reasoning and Alzheimer's disease data.
