Svm which kernel to use
SpletReport means testing accuracy. Use the optimum γ and report your testing accuracy and the value for γ. Find the Kernel SVM using your own ‘myGaussian’ function at γ (γ value obtained using 5-fold CV) Apply kernel SVM with any kernel of your choice other than ‘rbf’. Provide transformation function for the kernel. Here is the Matlab code.

SpletThis study focuses on an SVM classifier with a Gaussian radial basis kernel for a binary classification problem and proposes a novel adjustment method called b-SVM, for adjusting the cutoff threshold of the SVM, and a fast and simple approach, called the Min-max gamma selection, to optimize the model parameters of SVMs without carrying out an … SpletThe radial basis function (RBF) kernel is a good starting choice because most data are not linearly separable. Fortunately training an SVM is fast, so brute-forcing the kernel search …
