Aligning individual brains with Fused Unbalanced Gromov-Wasserstein
Alexis Thual, Huy Tran, Tatiana Zemskova +4
Individual brains vary in both anatomy and functional organization, even within a given species. Inter-individual variability is a major impediment when trying to draw generalizabl…
Fine-grain atlases of functional modes for fMRI analysis
Kamalaker Dadi, Gaël Varoquaux, Antonia Machlouzarides-Shalit +4
Population imaging markedly increased the size of functional-imaging datasets, shedding new light on the neural basis of inter-individual differences. Analyzing these large data en…
FAASTA: A fast solver for total-variation regularization of ill-conditioned problems with application to brain imaging
Gaël Varoquaux, Michael Eickenberg, Elvis Dohmatob +1
The total variation (TV) penalty, as many other analysis-sparsity problems, does not lead to separable factors or a proximal operatorwith a closed-form expression, such as soft thr…
Region segmentation for sparse decompositions: better brain parcellations from rest fMRI
Alexandre Abraham, Elvis Dohmatob, Bertrand Thirion +2
Functional Magnetic Resonance Images acquired during resting-state provide information about the functional organization of the brain through measuring correlations between brain a…
