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
Examples
>>> import openturns as ot >>> X = ot.Normal().getSample(10) >>> splitter = ot.LeaveOneOutSplitter(X.getSize()) >>> for indicesTrain, indicesTest in splitter: ... XTrain, XTest = X[indicesTrain], X[indicesTest]
