Abstract
This paper presents a fuzzy genetic approach to perform data classification. The
method aims to obtain small fuzzy classifiers by means of optimization of fuzzy
rules bases using a genetic algorithm. It is shown how a fuzzy rules base is
generated from a numerical database and how its best subset is found by the
genetic algorithm. The classifiers are evaluated in terms of accuracy, cardinality
and amounts of features employed. The results obtained are compared to a known
study in the literature and with an academic decision tree tool. The method was
able to produce small fuzzy classifiers with very good performance.
1 Introduction
Classification (Gordon, [I]) is an important task in each knowledge field. It
consists of classifying elements described by a fixed set of attributes into one of a
finite set of categories or classes. For example, to di
