Description
Once the active subspace variables have been identified, replace the
fullspace truth model with a moving least squares surrogate model over
the reduced variables. The surrogate is constructed using the
fullspace function value samples collected during subspace
identification, possibly supplemented with additional
refinement_samples
in the
fullspace.
Default Behavior
No surrogate is constructed by default.
Examples
