Abstract:
A computer-implemented method for visualizing a decision-tree classifier, comprising the steps of:mapping a structure of the decision-tree classifier into a three-dimensional decision-tree visualization, wherein the decision-tree classifier is induced from a training set, and wherein the three-dimensional decision-tree visualization represents the structure of the decision-tree classifier, wherein the three-dimensional decision-tree visualization includes nodes, the nodes in the three-dimensional decision-tree visualization including graphical objects representing nodes arranged in a hierarchy, the nodes in the three-dimensional decision-tree visualization corresponding to nodes in the decision-tree classifier;displaying the three-dimensional decision-tree visualization; andat each node in the three-dimensional decision-tree visualization, providing at least one graphical attribute representative of information at a corresponding node of the decision-tree classifier, wherein a graphical attribute represents the number of records in a class at each node, wherein said providing step comprises the step of:(a) at each node in the three-dimensional decision-tree visualization, providing at least one graphical attribute representative of the number of records in a class at the corresponding node of the decision-tree classifier.
