A New Method of Ascertaining Attribute Weight Based on Rough Sets Theory
Xinzhong Bao, Yingwen Liu · 2009
Attribute importance represented by rough set is studied deeply. Aiming at the shortcomings of existing methods of attribute weight assignment based on rough set, by considering both the overall significance degree and the individual significance degree of each attribute in the conditional attributes, a new method of attribute weight assignment based on rough set is proposed, which can improve the ability of generalization and interpretation.
