WebFor length scales below the minimum spacing of the covariates the GP likelihood plateaus. Unless regularized by a prior, this flat likelihood induces considerable posterior mass at small length scales where the observation variance drops to zero and the functions supported by the GP being to exactly interpolate between the input data.
WebEnsemble regression. With an ensemble of regressors, the standard deviation of the predictions at a given point can be thought of as a measure of disagreement. This can be used for active regression. In the following example, we are going to see how can it be done using the CommitteeRegressor class.
