Abstract

We present an extension of the lazy rule induction algorithm from [1]. We extended it to deal with real-value attributes and generalised its conditions for symbolic non-ordered attributes. The conditions for symbolic attributes are defined by means of a metric over attribute domain. We show that commonly used rules are a special case of the proposed rules with a specific metric. We also relate the proposed algorithm to the discretisation problem. We illustrate that lazy approach can omit the discretisation time complexity.
