Multivariate Alternating Decision Tree


Multivariate ADTree is multivariate extensions to Alternating Decision Tree (ADTree). These variants are Fisher's ADTree, Sparse ADTree, and Regularized Logistic ADTree. Regularization techniques such as Ridge, Lasso, and Elastic Net are incorporated into ADTree, a special decision tree induced based on boosting algorithm. Multivariate ADTree is also a Matlab toolbox and it has been developed by Hong Kuan Sok, Melanie Po-Leen Ooi, Ye Chow Kuang, and Serge Demidenko in year 2015. The Multivariate ADTree consists of a series of MATLAB functions. SpaSM toolbox** and Statistics and Machine Learning Toolbox are required to run the program. Here's a brief instruction on how to use the Multivariate ADTree:

Step1: Load the dataset in MATLAB

Step2: Set the parameters

Step3: Draw ADTree tree structure and decision rules are written in the specified file, i.e.,:


ADTreeModelDraw(ADTreeModel,dataset);

ADTreeModelWrite(ADTreeModel,dataset);


Examples are given in the zip file. Please refer to "demoADTree.m" and "demoLADTree.m".


**Sparse Statistical Modelling (SpaSM) is developed by the Department of Informatics at the Technical University of Denmark. The ADTree has no involvement in the development of SpaSM. Please visit the SpaSM link to understand the toolbox.
