摘要：This paper presents two kinds of rough set approximation definition based on neighborhood system, comparison of some kinds of approximation, and analysis of their related properties. Adopting Pawlak's method to measure the accuracy in three approximation definitions, that is, Lin's definition and two definitions presented in this paper. The conclusion is that the first approximation definition presented in this paper is more accurate than the other two. ? 2012 IEEE.
