Abstract
In this report, the prediction performances of two rule evaluation measures,
accuracy and weighted relative accuracy, are compared. These two measures
were used in two different versions of CN2 algorithm for inducing
classification rules. The first version (CN2-acc) is the original one, where
the accuracy measure for evaluating rules is used. The second one (CN2-wracc)
uses weighted relative accuracy. The performance of two versions of CN2 was
compared in sense of classification accuracy as well as number and length of
the induced rules.
