NettetGaussian process regression (GPR) models are nonparametric kernel-based probabilistic models. You can train a GPR model using the fitrgp function. Consider the training set { ( x i, y i); i = 1, 2, ..., n }, where x i ∈ ℝ d and y i ∈ ℝ, drawn from an unknown distribution. A GPR model addresses the question of predicting the value of a ...
