Constructing nominal X-of-N attributes

摘要: Most constructive induction researchers focus only on new boolean attributes. This paper reports a algorithm, called X-of-N, that constructs nominal attributes in the form of X-of-N representations An is Bet containing one or more attribute-value pairs. For given instance, its value corresponds to number pairs are true. The promising preliminary experimental results, both artificial and real-world domains, show constructing can significantly improve performance selective terms higher prediction accuracy lower theory complexity.
