Abstract:In this paper,Ziarko’s idea of variable precision inclusion is introduced in the fuzzy-rough set model.We use ?茁-precision aggregation operators to produce variable precision fuzzy-rough set,which is then used to the fuzzy data analysis of large databases.The developed model has certain tolerance to the noisy data,so its robustness of dealing with practical problems has been enhanced.Furthermore,the ability of adapting new situations as well as knowledge forecasting has also been improved.
Keywords:variable precision rough set  fuzzy-rough set  ?茁-precision aggregation  variable precision fuzzy-rough set
