- If the classes cannot be well separated by a hyper-plane, the SVM can be used to determine a quadratic or circumferential decision boundary. The SVM determines a nonlinear boundary in the input feature space by solving for linear boundary in higher-dimensional feature space, which is formed by introducing a kernel.
