Binary index tree tutorial
WebGini index. Another decision tree algorithm CART (Classification and Regression Tree) uses the Gini method to create split points. Where pi is the probability that a tuple in D belongs to class Ci. The Gini Index considers a binary split for each attribute. You can compute a weighted sum of the impurity of each partition.
