                          IllegalArgumentException

Parameters:

inputData - an array where each row corresponds to a single instance (to be classified) and the columns hold the attributes of that instance

targetClass - an array where each row corresponds to a single instance, specifically the actual classification of that instance. The class needs to be a number 0,1,2,...,N-1 where N is the number of classes. Some of these classes may have no examples.

Returns:

decisiontree

Throws:

DecisionTreeCreator.TreeCreationException

IllegalArgumentException
