C and gamma in svm
WebSep 29, 2024 · The most important parameters in the SVM class are C, and gamma. C refers to the distance of the margins the hyperplane separates between the classes. Default is 1 but higher C means smaller ... Webgamma defines how much influence a single training example has. The larger gamma is, the closer other examples must be to be affected. Proper choice of C and gamma is …
C and gamma in svm
Did you know?
WebC HyperParameter in SVM. C adds penalty to each misclassified point. If the C value is small, then essentially, the penalty for misclassified points is also small, thus resulting in a larger margin based boundary. If the C value is large, then SVM tries to minimize the number of misclassified points by reducing the margin width.
