Nettet16. jan. 2024 · Mathematically, linear Kernel is given by. \begin {aligned} K (x_1, x_2) = x_1^T x_2 \quad \implies \quad \phi (x) = x \end {aligned} Linear SVM is very efficient in high dimensional data applications. While their accuracy on test set is close to the non-linear SVM, it is much faster to train for such applications.

NettetOnce it has found the closest points, the SVM draws a line connecting them (see the line labeled 'w' in Figure 2). It draws this connecting line by doing vector subtraction (point A - point B). The support vector machine then declares the best separating line to be the line that bisects -- and is perpendicular to -- the connecting line.
