WebMar 8, 2024 · Support-Vectors. Support vectors are the data points that are nearest to the hyper-plane and affect the position and orientation of the hyper-plane. We have to select a hyperplane, for which the margin, i.e the distance between support vectors and hyper-plane is maximum. Even a little interference in the position of these support vectors can ... http://math.wsu.edu/faculty/xchen/stat437/LectureNotes6.html

WebAug 3, 2024 · Therefore, it is necessary to search for an optimal separating hyperplane to maximize the distance between the support vectors and the hyperplane . The distance from the hyperplane to a support vector is 1 ‖ w ‖; thus, we can get the distance between the support vectors of one class to the other class simply by using geometry: 2 ‖ w ‖. WebThis case is solved by using soft-margin SVM. Soft-margin SVMs include an upper bound on the number of training errors in the objective function of Optimization Problem 1. This upper bound and the length of the weight vector are then both minimized simultaneously. ... The SVM optimal hyperplane bisects the segment joining the two nearest points ...
