LeaveOneOutSplitter

class LeaveOneOutSplitter(*args)

Leave-one-out splitter.

Generates train/test indices to split samples in train/test sets. Each sample is used once as a test set while the remaining samples form the training set.

Parameters:

Nint

Size of the set of indices in which the indices are chosen

Methods

getClassName()	Accessor to the object's name.
getN()	Set size accessor.
getName()	Accessor to the object's name.
getSize()	Number of sets generated.
hasName()	Test if the object is named.
setName(name)	Accessor to the object's name.

Examples

>>> import openturns as ot
>>> sample = ot.Normal().getSample(10)
>>> splitter = ot.LeaveOneOutSplitter(sample.getSize())
>>> for indicesTrain, indicesTest in splitter:
...     sampleTrain, sampleTest = sample[indicesTrain], sample[indicesTest]
