Region-based quantitative and hierarchical attribute reduction in the two-category decision theoretic rough set model

作者：

Highlights：

• An improved type of classification regions and its preservation reduct are proposed.

• The set-region preservation target, property and reduct are studied.

• The double-preservation reduct of set regions and rule consistency is established.

• Hierarchies of three quantitative reducts and two qualitative reducts are explored.
