Gaussian Process Regression

Gaussian process regression models (kriging)

Gaussian process regression (GPR) models are nonparametric, kernel-based probabilistic models. To train a GPR model interactively, use the Regression Learner app. For greater flexibility, train a GPR model using the fitrgp function at the command line. After training, you can predict responses for new data by passing the model and the new predictor data to the predict object function.
