Rough set attribute reduction example demonstrating calculation of positive region, generation of unprocessed discernibility matrix, matrix simplification, core computation, and attribute reduction using processed discernibility matrix
A MATLAB library for rough set attribute reduction (contains examples, original implementation) featuring core M-file functions: TargetOptFcn.m - objective function for genetic algorithm optimization; PositiveRegion.m - computes positive region; LowerApproximation.m - calculates lower approximation; IsSub.m - determines if set A is a subset of set B; EquivalentClassSet.m - generates all equivalence classes based on R-classification (U/R); EleEquivalentSet.m - computes equivalence classes containing specific elements; DependencyDegree.m - calculates dependency degree between attributes
