F-Parallel Reducts in the Information View

Abstract

Parallel reducts in the information view and an algorithm with the matrix of attribute significance in the information view are introduced in this paper. Furthermore, F-attribute significance in the information view is defined, and its properties are investigated. We apply it to obtain parallel reducts, and an algorithm with F-attribute significance in the information view is proposed. Experiments show that our methods have advantages over dynamic reducts, and the new method not only improves the time efficiency but also decreases the length of parallel reducts.
