Neighborhood Systems and Variable Precision Generalized Rough Sets
Yu-Ru Syau, En-Bing Lin, Churn‐Jung Liau · Fundamenta Informaticae · 2017
In this paper, we present the connection between the concepts of Variable Precision Generalized Rough Set model (VPGRS-model) and Neighborhood Systems through binary relations. We provide characterizations of lower and upper approximations for VPGRS-model by introducing minimal neighborhood systems. Furthermore, we explore generalizations by investigating variable parameters which are limited by variable precision. We also prove some properties of lower and upper approximations for VPGRS-model.
