MATLAB: Out of Linear, Quadratic, Cubic and Gaussian, which kernel function of svm can I use to classify data into “5” classes

Question

Hi Out of Linear, Quadratic, Cubic and Gaussian, which kernel function of svm can I use to classify data into "5" classes? Thank you

Answer 1

Any of them. svm itself is not able to handle multiple classes, and the code that adds on multi-class support https://www.mathworks.com/help/stats/classificationecoc-class.html does not care which of the kernels you use.
