Description
Export the surrogate for later re-import to Dakota or evaluation using
the surfpack exectuable ( bin/surfpack
) or a user-developed
tool. Export format is controlled using the formats
specification. Four formats are available in Dakota; however, not all
have been enabled for all surrogates.
The four formats are:
text_archive
- Plain-text, machine-readable archive for re-import or use with the surfpack executablebinary_archive
- Binary, machine-readable archive for re-import or use with the surfpack executablealgebraic_file
- Plain-text, human-readable file intended for use with user-created tools; not compatible with Dakota or the surfpack executablealgebraic_console
- Print the model in algebraic format to the screen; not compatible with Dakota or the surfpack executable
These global surrogates can be exported in all four formats:
Gaussian process (keyword
gaussian_process
surfpack)Artificial neural network (keyword
neural_network
)Radial basis Funtions (keyword
radial_basis
)Polynomial (keyword
polynomial
)
However, for experimental Gaussian Process and polynomial models as
well as Multivariate Adaptive Regression Spline (keyword mars
) and
moving least squares (keyword moving_least_squares
) models, only
text_archive
and binary_archive
formats may be used.
Currently, no other surrogate models can be exported.
Default Behavior <p>No export.
Expected Output
<p>Output depends on selected format; see the formats
specification.
Additional Discussion <p>The Dakota examples include a demonstration of using the surfpack executable with an exported model file.
