Alias: none
Argument(s): none
Default: constantine
Child Keywords:
Required/Optional | Description of Group | Dakota Keyword | Dakota Keyword Description | |
---|---|---|---|---|
Optional | bing_li | Use the Bing Li "ladle" diagnostic to truncate subspace | ||
Optional | constantine | Use the Constantine diagnostic to truncate subspace | ||
Optional | energy | Truncate the subspace based on eigenvalue energy | ||
Optional | cross_validation | Truncate the subspace to minimize surrogate cross-validation error |
Metric that controls how many basis vectors are retained in the active subspace.
Default Behavior
The default is to use the constantine diagnostic.
Usage Tips
If the automated subspace identification methods do not yield desirable results, consider using the explicit dimension truncation option.
