WebApr 8, 2024 · GaussianProcessRegressor from Scikit-Learn Note that in the examples above he had to compute the inverse of \(K(X,X) + \sigma_n^2 I\) , which can be computationally expensive for larger data sets. A better approach is to use the Cholesky decomposition of \(K(X,X) + \sigma_n^2 I\) as described in Gaussian Processes for …

Fit SVR (polynomial kernel) Epsilon-Support Vector Regression . The free parameters in the model are C and epsilon. The implementation is based on libsvm. The fit time complexity is more than quadratic with the number of samples which makes it hard to scale to datasets with more than a couple of 10000 samples.
