  • A fuzzy decision tree-based SVM classifier for assessing osteoarthritis severity using ground reaction force measurements 

    Moustakidis, S. P.; Theocharis, J. B.; Giakas, G. (2010)
    A novel fuzzy decision tree-based SVM (FDT-SVM) classifier is proposed in this paper, to distinguish between asymptotic (AS) and osteoarthritis (OA) knee gait patterns and to investigate OA severity using 3-D ground reaction ...
