| Abstract: | Rough set theory has being aimed at data analysis problems involving uncertain or imprecise information.Based on the relative concepts of variable precision rough set model,the paper makes a lucubration on reduct anomaly, analyzes the reduct anomaly when inclusion degree vibrates and positive area changes.It also presents some basic ideas to eliminate reduct anomaly and develops the variable precision rough set model. |
