DESCRIPTION
Given a Binning Transformation containing the definition of the bins, and an Example Table that has the input/ output attribute labels and types, this module builds a Bin Tree that can be later used to classify data. A Bin Tree holds information about the number of examples that fall into each bin for each class. The Bin Tree can use only one output feature as a class. If more are selected in the Example Table, only the first one will be used.Scalability: a large enough number of features will result in an OutOfMemory error. Use feature selection to reduce the number of features.
