Spatio-temporal models of mental processes from fMRI

► Multivariate spatio-temporal model of mental processes using state-space formalism. ► Semi-supervised method allowing for discovery of intrinsic patterns in data. ► Novel feature-space derived from an explicit formulation of functional similarity. ► Efficient estimation using expectation maximization with mean-field approximation. ► Comparative and quantitative single and multi-subject analysis results.
