Optimal soft margin hyperplane

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 ... WebDec 12, 2024 · To train a support vector classifier, we find the maximal margin hyperplane, or optimal separating hyperplane, which optimally separates the two classes in order to generalize to new data and make accurate classification predictions. ... “Soft margin” classification can accommodate some classification errors on the training data, in the ...
