We introduce a novel framework for estimating vector fields using sparse basis field expansions (S-FLEX). The notion of basis fields, which are an extension of scalar basis functions, arises naturally in our framework from a rotational in- variance requirement. We consider a regression setting as well as inverse prob- lems. All variants discussed lead to second-order cone programming formula- tions. While our framework is generally applicable to any type of vector field, we focus in this paper on applying it to solving the EEG/MEG inverse problem. It is shown that significantly more precise and neurophysiologically more plausible location and shape estimates of cerebral current sources from EEG/MEG measure- ments become possible with our method when comparing to the state-of-the-art. |
