KFold

class KFold(*args)

K-fold.

Parameters

kpositive integer

Number of folds in which the sample is splitted. If not provided, default is .

Notes

KFold inherits from FittingAlgorithm.

This class is not usable on its own because it has sense only within the FunctionalChaosAlgorithm.

Methods

getId()	Accessor to the object's id.
getK()	Accessor to the number of folds.
getName()	Accessor to the object's name.
getShadowedId()	Accessor to the object's shadowed id.
getVisibility()	Accessor to the object's visibility state.
hasName()	Test if the object is named.
hasVisibleName()	Test if the object has a distinguishable name.
run(x, y, weight, basis, indices)	Run the algorithm.
setK(p)	Accessor to the number of folds.
setName(name)	Accessor to the object's name.
setShadowedId(id)	Accessor to the object's shadowed id.
setVisibility(visible)	Accessor to the object's visibility state.
