Detailed Description

Subspace model for input (variable space) reduction.

Specialization of a RecastModel that identifies a subspace during build phase and creates a RecastModel in the reduced space

Member Function Documentation

◆ initialize_mapping()

bool initialize_mapping ( ParLevLIter pl_iter )

virtual

May eventually take on init_comms and related operations. Also may want ide of build/update like DataFitSurrModel, eventually.

Reimplemented from RecastModel.

References SubspaceModel::component_parallel_mode(), SubspaceModel::compute_subspace(), RecastModel::initialize_mapping(), SubspaceModel::initialize_subspace(), SubspaceModel::miPLIndex, Model::modelPCIter, SubspaceModel::numFullspaceVars, and SubspaceModel::reducedRank.

◆ derived_evaluate()

void derived_evaluate ( const ActiveSet & set )

protectedvirtual

portion of evaluate() specific to RecastModel (forward to subModel.evaluate())

The RecastModel is evaluated by an Iterator for a recast problem formulation. Therefore, the currentVariables, incoming active set, and output currentResponse all correspond to the recast inputs/outputs.

Reimplemented from RecastModel.

References Dakota::abort_handler(), SubspaceModel::component_parallel_mode(), RecastModel::derived_evaluate(), and Model::mappingInitialized.

◆ uncertain_vars_to_subspace()

void uncertain_vars_to_subspace ( )

protectedvirtual

translate the characterization of uncertain variables in the native_model to the reduced space of the transformed model

Convert the user-specified normal random variables to the appropriate reduced space variables, based on the orthogonal transformation.

TODO: Generalize to convert other random variable types (non-normal)

TODO: The translation of the correlations from full to reduced space is likely wrong for rank correlations; should be correct for covariance.

Reimplemented in AdaptedBasisModel, and ActiveSubspaceModel.

protected

Initialize the base class RecastModel with reduced space variable sizes.

Initialize the recast model based on the reduced space, with no response function mapping (for now). TODO: use a surrogate model over the inactive dimension.

◆ set_mapping()

void set_mapping	(	const Variables &	reduced_vars,
		const ActiveSet &	reduced_set,
		ActiveSet &	full_set

staticprotected

map the inbound ActiveSet to the sub-model (map derivative variables)

Simplified derivative variables mapping where all continuous depend on all others. TODO: Could instead rely on a richer default in RecastModel based on varsMapIndices.
