Comparison Of Fuzzy And Crisp Classification Trees Using Gini Index, Chi-square Statistic And The Gain Ratio

ABSTRACT Discriminant (classification) analysis is a classification problem where a new individual is allocated into one of known populations or classes based on the measured characteristics of the individual. Different models are used in allocating the new individual into one of the populations (classes). Some of the models depend on the underlying distribution of the populations, hese are known as parametric models. If the model does not depend on any underlying distribution it is known as a distribution free or non parametric model. In this work a distribution free model known as classific…
