All these algorithms use a greedy, top-down recursive partitioning approach. They primarily differ in terms of the splitting criteria, the type of splits (2-way or multi-way) and the handling of the overfitting problem. DTI uses a greedy, top-down recursive partitioni ng approach to induce a decision tree from data.
