WebLecture 2 - Massachusetts Institute of Technology WebSolving the SVM means solving a constrained quadratic program. Solutions can be sparse – some coefﬁcients are zero. The nonzero coefﬁcients correspond to points that aren’t classiﬁed correctly enough – this is where the “support vector” in SVM comes from. C. Frogner Support Vector Machines
