Method Detail

add

public boolean add(Instance i)

Description copied from interface: Dataset

Add an instance to this data set. The compatibility of the new item with the items in the data set should be checked by the implementation. Incompatible items should not be added to the data set.

Specified by:

add in interface java.util.Collection<Instance>

Specified by:

add in interface java.util.List<Instance>

Specified by:

add in interface Dataset

Parameters:

i - the instance to be added

Returns:

true if the instance was added, otherwise false

classes

public java.util.SortedSet<java.lang.Object> classes()

Description copied from interface: Dataset

Returns a set containing all different classes in this data set. If no classes are available, this will return the empty set.

Specified by:

numFolds - the number of folds to create

rg - the random generator

Returns:

an array of data sets that contains numFolds data sets.

instance

public Instance instance(int index)

Description copied from interface: Dataset

Get the instance with a certain index.
