How kernel tricks work in svm
Web21 sep. 2024 · 1 Recommendation. The kernel is essentially a mapping function - one that transforms a given space into some other (usually very high dimensional) space. As it … 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.
