Required | formats | Formats for surrogate model export |
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 executable binary_archive
- Binary, machine-readable archive for re-import or use with the surfpack executable algebraic_file
- Plain-text, human-readable file intended for use with user-created tools; not compatible with Dakota or the surfpack executable algebraic_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
surfpack) neural_network
) radial_basis
) 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
No export.
Expected Output
Output depends on selected format; see the formats
specification.
Additional Discussion
The Dakota examples include a demonstration of using the surfpack executable with an exported model file.
