Module egobox_gp::mean_models

A module for regression models to model the mean term of the GP model. In practice small degree (<= 2) polynomial regression models are used, as the gaussian process is then fitted using the correlated error term.

The following models are implemented:

• constant,
• linear,
• quadratic

Structs

• ConstantMean
  A constant function as mean of the GP
• LinearMean
  An affine function as mean of the GP
• QuadraticMean
  A 2-degree polynomial as mean of the GP

Traits

• RegressionModel
  A trait for mean models used in GP regression
