Abstract :
Multi-granulation rough set model is an important generalization of Pawlak´s rough set model. To enhance its capability of dealing with noisy data, in this paper, we proposed the variable precision multi-granulation rough set model and the variable precision weighted multi-granulation rough set model by loosing the requirement of accuracy on each granulation. Furthermore, we gave some important properties, and analyzed the relationships between existing multi-granulation rough set models and the proposed models.
