Computer-Aided Diagnostics of Heart Disease Risk Prediction Using Boosting Support Vector Machine

Algorithm 1

Gini index computation.

	Gini Index:
	for each branch in split:
	Calculate percent branch represents #Used for weighting
	for each class in branch:
	Calculate probability of class in the given branch.
	Square the class probability.
	Sum the squared class probabilities.
	Subtract the sum from 1.
	Weight each branch based on the baseline probability.
	Sum the weighted gini index for each split.
