Summary

It is argued that, in order to improve classifier performance, it may be more useful to focus on the small disjuncts problem than it is tofocus on the class imbalance problem, and experiments suggest that the problem is not directly caused by class imbalances, but rather, that class imbalance may yield small disJuncts which will cause degradation.
