WebSVM kernels are functions based on which we can transform the data so that it is easier to fit a hyperplane to segregate the points better. Linearly separable points consist of points that can be separated by a simple straight line. The line has to have the largest margin possible between the closest points to form a generalized SVM model. 2.
