KennardStone(X, TrainSamples; distance = "euclidean")

Returns the indices of the Kennard-Stone sampled exemplars (E), and those not sampled (O) as a 2-Tuple (E, O).

Note: there is an indexing bug here...

SplitByProportion(X::Array, Proportion::Float64 = 0.5)

Splits X Array along the observations dimension into a 2-Tuple based on the Proportion. The form of the output is the following: ( X1, X2 )

SplitByProportion(X::Array, Y::Array,Proportion::Float64 = 0.5)

Splits an X and Associated Y Array along the observations dimension into a 2-Tuple of 2-Tuples based on the Proportion. The form of the output is the following: ( (X1, Y1), (X2, Y2) )

VenetianBlinds(X,Y)

Splits an X and associated Y Array along the observation dimension into a 2-Tuple of 2-Tuples based on the whether it is even or odd. The form of the output is the following: ( (X1,Y1), (X2, Y2) )

VenetianBlinds(X)

Splits an X Array along the observations dimension into a 2-Tuple of 2-Tuples based on the whether it is even or odd. The form of the output is the following: ( X1, X2 )
