WebbIf we change to soft-margin SVM with slack variable C, and changing the notation of label. We could generate a run time comparison betwenn Primal solution and Dual solution. The run time for Dual solution is almost one-half to the Primal in changing of slack variable or changing sample size, which makes it a more convenient way of solving SVM. Webbmeaning an algorithm like gradient ascent might be used to solve the Lagrange dual problem. • No easy solution. If f0(x) is complicated enough, it is going to be very hard to solve the inner minimization, not matter the constraints.
