TreeView, exploration interactive des arbres de décision

Abstract

We propose a graphical environment using the new radial tree layout, zoom/pan techniques and some existing methods, including explorer-like, hierarchical visualization, interactive techniques to represent large decision trees in a graphical mode more intuitive than the results in output of usual decision tree algorithms. The interactive exploration system on one hand can present the global view and on the other hand, it also provides a very good performance for an interesting sub-tree with simplicity, speed of task completion, ease of use and user understanding. The user can easily extract inductive rules and prune the tree in the post-processing stage. The numerical test results with real datasets show that the proposed methods have given an insight into decision tree results. It can guide the user towards for evaluating the models and also making more accurate decisions.
