Tri-level attribute reduction in rough set theory
作者：
Highlights：
• Object-specific attribute reducts are proposed by object consistency from dependency.
• Object-specific reducts improve classification-specific and class-specific reducts.
• Tri-level attribute reducts present both series development and hierarchy deepening.
• Tri-level reducts gain hierarchical relationships and transitions, direct calculations.
• Tri-level thinking and analysis of attribute reduction enrich three-way Gr-Computing.
