A Rule Abstracting Algorithm of Decision Tree Based on Rough Set
TLDR
A new algorithm for classification rules extraction by choosing attributes of importance of attributes and dependance based on rough set is presented, which can extract crisp rules from classification information system.Abstract:
The decision tree is a usual method of classification in data mining.In the process of constructing a decision tree,the criteria of selecting attributes to split will influence the efficiency of classification directly.The decision tree algorithm traditionally is based on information theory measure.Presented a new algorithm for classification rules extraction by choosing attributes of importance of attributes and dependance based on rough set.Using this algorithm,can extract crisp rules from classification information system.Compared with the traditional ID3 algorithm,it's simpler in the structure,and can improve the efficiency of classification.read more
