| Abstract: | Attribute reduction and value reduction are the basis of learning from examples based on rough set.This paper studies the problem of attribute reduction firstly.Then,it puts forward an improved reduction algorithm based on the dependence and importance of attribute to get compact rules,which improves the efficiency of learning from examples.Lastly,the correctness and effectiveness of the new algorithm are shown by an example. |
