Neighborhood Systems: Rough Set Approximations and Definability
Fundamenta Informaticae, 2018The notions of approximation and definability in classical rough set theory and their generalizations have received much attention. In this paper, we study such generalizations from the perspective of neighborhood systems. We introduce four different types of definability, called interior definability, closure definability, interior-closure (IC ...

A Fast Attribute Reduction Algorithm of Neighborhood Rough Set
2021 13th International Conference on Knowledge and Smart Technology (KST), 2021The classic Pawlak rough set model is only suitable for processing discrete data, not continuous data directly. Pawlak rough set model needs discretization when processing continuous data, which will cause the loss of information in the data set. In this context, Hu proposed the neighborhood rough set (NRS) model, which greatly expanded the application

Neighborhood rough sets for dynamic data mining
International Journal of Intelligent Systems, 2012Approximations of a concept in rough set theory induce rules and need to update for dynamic data mining and related tasks. Most existing incremental methods based on the classical rough set model can only be used to deal with the categorical data. This paper presents a new dynamic method for incrementally updating approximations of a concept under ...

Neighborhood Systems and Variable Precision Generalized Rough Sets
Fundamenta Informaticae, 2017In 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.

Variable precision neighborhood rough sets on two universes
2013 IEEE International Conference on Granular Computing (GrC), 2013The theory of rough sets on two universes has brought the attention by many scholars in recent years. In this paper, we propose the variable precision neighborhood rough sets model on two universes. Furthermore, the properties of this model are studied. Finally, we investigate the uncertainty measures and give a test example.
