- Abstract
The fuzzy information system over two universes formalizes a data table corresponding to two universes as well as their relations. Although many analyses have focused on this topic, the existing models are mixed with some uncertain factors in the process of given relation. And it is unnecessary to analyze the fuzzy objects with small membership degree. This motivates us to develop a better method to handle complex data. This paper proposes a local fuzzy rough set model over two universes, then further analyzes its properties and decision rules. Moreover, the reduction method of the model is being studied. The experiment results show that the proposed model has better performance in classfication and decision-making.
