Abstract

This paper proposes a new framework for incremental learning based on accuracy and coverage. Classification of addition of example into four cases gives two inequalities for accuracy and coverage. The proposed method classifies a set of formulae into three layers: rule layer, subrule layer and non-rule layer by using the inequalities obtained. Then, subrule layer plays a central role in updating rules. The proposed method was evaluated on a dataset on meningitis, whose results show that it outperforms other conventional rule induction methods.
