双论域上基于加权粒度的多粒度粗糙集
Multi-granulation Rough Set Based on Weighted Granularity on the Two Universes
摘要
Abstract
Aiming at the shortcomings of multi-granularity rough set in the discussion of granularity weighted and universe ex?pansion problem,multi-granularity rough set based on weighted granularity on the two universes is proposed. This model considers the importance of different granularity in practice. On this basis,the nature of the model is discussed,and the model is applied to the talent selection to verify its effectiveness. Through the comparative analysis of the model,it is found that the new model improves the time efficiency while ensuring the accuracy of the results. The rough set model has a better effect than the single universe and the general granularity relation.关键词
