In the formulation of SVM, we need to compute the margin (i.e., the distance) between an arbitrary point x() in the N-dimensional space and a hyperplane wx + b = 0, which can be formulated as the following optimization problem: min ||-||2 I s.t. wx+b=0. Using the Lagrange duality to solve for the optimal x and the distance. (Remember to form the Lagrangian and derive the Lagrange dual function).
