Learn more about gaussian kernel, radial basis function, the standard diviation, width of the kernel MATLAB Gaussian kernel scale for RBF SVM. Learn more about svm, kernel scale, gaussian kernel, classification learner Kernel Ridge Regression with gaussian kernel and k-Fold cross-validation KRR. The five Matlab scripts found in the root directory of this repository are tools for using the kernel ridge regression algorithms. With the use of these matlab scripts you can easily implement and evaluate the KRR algorithm on any set of continuous floating point data. For greater accuracy on low- through medium-dimensional data sets, train a support vector machine (SVM) model using fitrsvm.. For reduced computation time on high-dimensional data sets, efficiently train a linear regression model, such as a linear SVM model, using fitrlinear.
