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. WebbOur problem solving pages provide a simple and structured approach to problem solving. The approach referred to is generally designed for problem solving in an organisation or group context, but can also be easily adapted to work at an individual level at home or in education. Trying to solve a complex problem alone however can be a mistake.
