| Abstract: | This paper summarizes two kinds of attributes reduction algorithm, brings up the definition of differentiability matrix on the basis of the discernibility matrix for the first time, and analyses its basic characters. Then gives an algorithm, and this algorithm is confirmed to have improvements by compared with the other algo- rithms. |
