Multivariate Wasserstein Functional Connectivity for Autism Screening

no code implementations23 Sep 2022 Oleg Kachan, Alexander Bernstein

Most approaches to the estimation of brain functional connectivity from the functional magnetic resonance imaging (fMRI) data rely on computing some measure of statistical dependence, or more generally, a distance between univariate representative time series of regions of interest (ROIs) consisting of multiple voxels.
