WebHowever, if we use an RBF kernel then we cannot represent the classifier of a hyper-plane of finite dimensions. Instead we have to store the support vectors and their corresponding dual variables $\alpha_i$ -- the number of which is a function of the data set size (and complexity). Hence, the kernel-SVM with an RBF kernel is non-parametric. WebBut if you need something that works pretty well in general, a constant kernel and RBF can be combined easily: from sklearn.gaussian_process import GaussianProcessRegressor from sklearn.gaussian_process.kernels import RBF, ConstantKernel as C gp = GaussianProcessRegressor(kernel = C() * RBF()) gp . fit(np . atleast_2d(xs) . reading list edge browserWebFirst, import all relevant kernels from scikit-learn to redefine the kernel.
