New data analysis method in incomplete information system with hybrid value
摘要
Abstract
Thie paper proposed a new improved ROUSTIDA algorithm to deal with incomplete information system with hybrid value. Firstly, gave an extended definition of discernibility matrix to deal with incomplete information system with hybrid value within the scope of neighborhood, then expounded the specific method combined with the technique of maximal consistent block, so greatly improved the ability to pack data, meanwhile the method had the good capacity of eliminating the elementary noise. Finally, an example is given to show that the presented algorithm is reasonable and efficient.关键词
