Construct moving least squares surrogate over active subspace
Alias: none
Argument(s): none
Child Keywords:
Required/Optional | Description of Group | Dakota Keyword | Dakota Keyword Description | |
---|---|---|---|---|
Optional | refinement_samples | Number of supplementary surrogate build samples |
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.
