1.1 Introduction The problem of data classification has numerous applications in a wide variety of mining ap-

plications. This is because the problem attempts to learn the relationship between a set of feature variables and a target variable of interest. Since many practical problems can be expressed as associations between feature and target variables, this provides a broad range of applicability of this model. The problem of classification may be stated as follows:

Given a set of training data points along with associated training labels, determine the class label for an unlabeled test instance.
