WebThe Support Vector Machine (SVM) is a state-of-the-art classi cation method introduced in 1992 by Boser, Guyon, and Vapnik [1]. The SVM classi er is widely used in bioinformatics (and other disciplines) due to its high accuracy, ability to deal with high-dimensional data such as gene ex-pression, and exibility in modeling diverse sources of ... WebSupport Vector Machines Support Vector Machines So far, we have only considered decision boundaries that are hyperplanes. But if the boundaries are actually nonlinear, hyperplanes won’t work well. The support vector machine, or SVM, extends the support vector classifier by enlarging the feature space using kernels.
