Decision region distribution preservation reduction in decision-theoretic rough set model

G Wang, H Yu, T Li - Information sciences, 2014 - Elsevier
In the Pawlak rough set model, the positive region, the boundary region and the non-
negative region are monotonic with respect to the set inclusion of attributes. However, the …

Non-monotonic attribute reduction in decision-theoretic rough sets

H Li, X Zhou, J Zhao, D Liu - Fundamenta Informaticae, 2013 - content.iospress.com
For most attribute reduction in Pawlak rough set model (PRS), monotonicity is a basic
property for the quantitative measure of an attribute set. Based on the monotonicity, a series …

Minimum cost attribute reduction in decision-theoretic rough set models
