Decision tree Although decision tree classifiers have achieved success in many domains, we have not seen a public domain package that can handle large classification problems that require a large number of classes and attributes. The goal of this project is to develop a decision tree package free to the public that can handle these problems.

This is the first beta release of the decision tree package developed at ISIP. The package contains a suit of well-known decision tree algorithms in a common framework. The code is written in C++ following the object-oriented data-driven paradigm.

The current package features:
  • Bayesian splitting
  • Information gain splitting
  • Gain ratio splitting
  • Pessimistic pruning
The package has been used in the following applications: The algorithm details of this package can be found at the following Master's project presentations: Feel free to download the code and give us your feedback. We look forward to your suggestions.
