| The relationship between constructive induction and domain knowledge can be analyzed systematically. Recent research has integrated knowledge and constructive induction in isolated domains with some success, but undue emphasis is often given to the technique developed rather than the underlying phenomena. In contrast, understanding how knowledge affects a domain's constructed feature space and instance space allows us to find better techniques more easily. Three case studies (bankruptcy, turfgrass management, and promoters) demonstrate how analysis of knowledge drives development of techniques. Although knowledge in each domain has its peculiarities, general relationships may be discovered that lead to a more principled approach to incorporating knowledge into constructive induction. |
