Comparison of two exploratory data analysis methods for fMRI unsupervised clustering versus independent component analysis.

Comparison of two exploratory data analysis methods for fMRI unsupervised clustering versus independent component analysis.

Exploratory data-driven methods such as unsupervised clustering and independent component analysis (ICA) are considered to be hypothesis-generating procedures, and are complementary to the hypothesis-led statistical inferential methods in functional magnetic resonance imaging (fMRI). In this paper,...
