Member Function Documentation

getNumGrids()

virtual size_t sgpp::datadriven::MultiGridRefinementFunctor::getNumGrids ( )

pure virtual

Returns the number of grids the functor can / does refine.

Implemented in sgpp::datadriven::DataBasedRefinementFunctor, sgpp::datadriven::ZeroCrossingRefinementFunctor, sgpp::datadriven::GridPointBasedRefinementFunctor, and sgpp::datadriven::MultiSurplusRefinementFunctor.

preComputeEvaluations()

virtual void sgpp::datadriven::MultiGridRefinementFunctor::preComputeEvaluations ( )

inlinevirtual

Used if expensive computations (eg.

grid evaluations) are cached, usually for one refinement step.

Reimplemented in sgpp::datadriven::ZeroCrossingRefinementFunctor, and sgpp::datadriven::GridPointBasedRefinementFunctor.

Referenced by sgpp::datadriven::RefinementHandler::handleDataAndZeroBasedRefinement(), sgpp::datadriven::ModelFittingClassification::refine(), and sgpp::datadriven::LearnerSGDE::trainOnline().

setGridIndex()

virtual void sgpp::datadriven::MultiGridRefinementFunctor::setGridIndex ( size_t  grid_index )

pure virtual

Sets the index (into the vector of grids) of the grid to be refined.

Parameters

grid_index

The index of the grid to be refined

Implemented in sgpp::datadriven::DataBasedRefinementFunctor, sgpp::datadriven::ZeroCrossingRefinementFunctor, sgpp::datadriven::GridPointBasedRefinementFunctor, and sgpp::datadriven::MultiSurplusRefinementFunctor.

Referenced by sgpp::datadriven::RefinementHandler::handleDataAndZeroBasedRefinement(), sgpp::datadriven::ModelFittingClassification::refine(), and sgpp::datadriven::LearnerSGDE::trainOnline().
