Set Approximation Quality Measures in the Variable Precision Rough Set Model
Wojciech Ziarko · HIS eBooks · 2002
The article introduces the basic notions of the variable precision rough set model (VPRS) including the parametric definitions of lower approximation, bound- ary and negative regions of a set. The main focus of the article is on the evaluation of the resulting set approximations and probabilistic decision tables using a number of proposed probabilistic measures. The application of the measures to evaluation of probabilistic decision tables is illustrated with a comprehensive example.
