In statistics, the Matérn covariance, also called the Matérn kernel, is a covariance function used in spatial statistics, geostatistics, machine learning, image analysis, and other applications of multivariate statistical analysis on metric spaces. It is named after the Swedish forestry statistician Bertil Matérn. It specifies the covariance between two measurements as a function of the distance between the points at which they are taken.

"WebIn most applications of BO, a radial basis function (RBF) or Matern kernel is used because they allow us the flexibility to fit a wide variety of functions in high dimensions. By default, BoTorch uses the Matern 5/2 kernel, which tends to allow for less smooth surfaces compared to the RBF. " - Botorch matern kernel
