An Improved DM Algorithm Based on Rough Set Theory
The basic idea of an improved algorithm is outlined in this paper firstly, includes main steps and the advantages and disadvantages of CART algorithm; and then the definitions of attribute importance and the system comprehensive information entropy and the algorithm of maintaining maximum system comprehensive information entropy are presented. Compares to some disadvantages of CART algorithm such as low computation efficiency of extraction rules and long rule length, the improved algorithm has effect in the experimental result.
