At the present time a large number of AI methods have been developed in the
field of pattern classification. In this paper, we will compare the perfor
mance of a well-known algorithm in machine learning (C4.5) with a recently
proposed algorithm in the fuzzy set community (NEFCLASS). We will compare t
he algorithms both on the accuracy attained and on the size of the induced
rule base. Additionally, we will investigate how the selected algorithms pe
rform after they have been pre-processed by discretization and feature sele
ction. (C) 1998 Elsevier Science Ltd. All rights reserved.
