Uncertainty measures of Neighborhood System-based rough sets
We first study the uncertainty of rough sets in binary GrC Model (Third GrC Model). We first propose the rough memberships to depict rough sets. Construct fuzzy entropy based on rough memberships and prove its rationality. We first propose the rough intuitionistic memberships to depict rough sets. Construct intuitionistic fuzzy entropy to measure uncertainty of rough sets.
