δ-Cut Decision-Theoretic Rough Set Approach: Model and Attribute Reductions
Decision-theoretic rough set is a quite useful rough set by introducing the decision cost into probabilistic approximations of the target. However, Yao's decision-theoretic rough set is based on the classical indiscernibility relation; such a relation may be too strict in many applications. To solve this problem, a δ-cut decision-theoretic rough set is proposed, which is based on the δ-cut quan...
متن کاملAttribute Reduction in Utility-Based Decision-Theoretic Rough Set Models
Decision-theoretic rough set (DTRS) model, proposed by Yao in the early 1990’s, introduces Bayesian decision procedure and loss function in rough set theory. Considering utility function in decision processing, utility-based decision-theoretic rough set model (UDTRS) is given in this paper. The utility of the positive region, the boundary region and the negative region are obtained respectively...
متن کاملDecision-Theoretic Rough Set Models
Decision-theoretic rough set models are a probabilistic extension of the algebraic rough set model. The required parameters for defining probabilistic lower and upper approximations are calculated based on more familiar notions of costs (risks) through the well-known Bayesian decision procedure. We review and revisit the decision-theoretic models and present new results. It is shown that we nee...
متن کاملIntuitionistic Fuzzy Dominance-based Rough Set Approach: Model and Attribute Reductions
The dominance–based rough set approach plays an important role in the development of the rough set theory. It can be used to express the inconsistencies coming from consideration of the preference–ordered domains of the attributes. The purpose of this paper is to further generalize the dominance–based rough set model to fuzzy environment. The constructive approach is used to define the intuitio...
متن کاملAttribute Reduction in Decision-Theoretic Rough Set Model: A Further Investigation
The monotonicity of positive region in PRS (Pawlak Rough Set) and DTRS (Decision-Theoretic Rough Set) are comparatively discussed in this paper. Theoretic analysis shows that the positive region in DTRS model may expand with the decrease of the attributes, which is essentially different from that of PRS model and leads to a new definition of attribute reduction in DTRS model. A heuristic algori...
