CART Viewer

The CART-Viewer dumps a CART(aka decision tree) in XML-, text-, or DOT- format and allows the interactive browsing of the CART.

Parameters:

decision-tree-file : see CART Estimation and CART Trainer

Channels:

decision-tree.xml : dump the decision tree in XML-format

decision-tree.plain : dump the decision tree in text-format

decision-tree.dot : dump the decision tree in DOT-format

Interactive CART browsing:

An input mask asks the user to define values for the properties used by the decision tree. The value of a property can be left open (empty input). The viewer can be run in two modes: classification and multification. In classification mode a single final class is found and the path trough the tree, i.e. the questions asked, are printed. In case of a question addressed to an undefined property, the answer NO is assumed. In multification mode all possible classes are printed. That is, in case of a question addressed to an undefined property both paths, i.e. the YES- and the NO-path, are followed.
