Hybrid intelligent systems: Selecting attributes for soft-computing analysis

Abstract

It is difficult to provide significant insight into any hybrid intelligent system design. We offer an informative account of the basic ideas underlying hybrid intelligent systems. We propose a balanced approach to constructing a hybrid intelligent system for a medical domain, along with arguments in favor of this balance and mechanisms for achieving a proper balance. This first of a series of contributions to hybrid intelligent systems design focuses on selecting attributes for soft-computing analysis. One part of this first contribution in our system is developed. Two definitions, probe and probe reducts, are introduced. Our CDispro algorithm can produce the core attribute and reducts that are essential condition attributes in data sets. Our initial study tests data from the UCI repository and geriatric data from DalMedix. The performance and utility of generated reducts are evaluated by 3-fold cross-validation that illustrates reduced dimensionality and complexity of data sets and processes. © 2005 IEEE.
