Abstract:Functional Magnetic Resonance Imaging (fMRI) is a neuroimaging technique used to capture images of brain activity. These images have high spatial resolution and hence are very high dimensional. Each scan consists of more than one hundred thousand voxels. All of the scanned voxels are not activated for every stimulus. Therefore, finding the informative voxels with respect to stimulus becomes a prerequisite for any machine learning solution using fMRI data. The specific problem attempted to be solved in this pap… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
