文摘

Constructs three-way regions with probabilistic rough sets and Gini coefficients. Measures the impurities of three-way regions with Gini coefficients. Analyzes the relationship among region impurity and performance changes. Formulates Gini objective functions to balance the impurities of three-way regions. Demonstrates the use Gini objective functions compares them with entropy approaches.
