WebMultivariate Gaussian Process Regression¶. When we say “multivariate” here we refer to many function inputs, not outputs. This just means that the input of the function we are interested in learning is a vector \(\mathbf{x}\) in \(\mathbb{R}^D\).In that regard, nothing really changes compared to one-input GPR.
