LeastSquaresMetaModelSelectionFactory¶
- class LeastSquaresMetaModelSelectionFactory(*args)¶
Least squares metamodel selection factory.
- Available constructors:
LeastSquaresMetaModelSelectionFactory()
LeastSquaresMetaModelSelectionFactory(basisSeqFac)
LeastSquaresMetaModelSelectionFactory(basisSeqFac, fittingAlgo)
- Parameters:
- basisSeqFac
BasisSequenceFactory
A basis sequence factory.
- fittingAlgo
FittingAlgorithm
A fitting algorithm.
- basisSeqFac
Notes
Implementation of an approximation algorithm implementation factory which builds an
ApproximationAlgorithm
.This class is not usable because it has sense only within the
FunctionalChaosAlgorithm
.Examples
>>> import openturns as ot >>> basisSequenceFactory = ot.LARS() >>> fittingAlgorithm = ot.CorrectedLeaveOneOut() >>> approximationAlgorithm = ot.LeastSquaresMetaModelSelectionFactory( ... basisSequenceFactory, fittingAlgorithm)
