Optimal Hyperplanes Margin of a Linear Classifier

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 ... WebA natural choice of separating hyperplane is optimal margin hyperplane (also known as optimal separating hyperplane) which is farthest from the observations.
