| 摘 要： | 提出一种信息观下的差别矩阵,并基于该矩阵设计了一种信息观下决策表的属性约简算法,该算法以信息观下属性核为起点,通过计算信息观下差别矩阵中各属性出现的频率确定属性的重要度,进而根据各个属性的重要度来计算属性约简。实验结果表明,该算法可以求出更有效的信息观下属性约简,且计算约简耗时更少。 |
| 关 键 词： | 差别矩阵 属性约简 |

| Abstract: | A new discernibility matrix in the information view is proposed.Thus an algorithm based on the discernibility matrix is constructed,by means of which we can acquire the reducts and the core of a decision table in the information view.The numerical experiment shows that the algorithm can obtain the same reduct as Hu's algorithm,and the time consuming of this algorithm is less than the one of Hu's algorithm. |
| Keywords: | discernibility matrix Attribute reduction |
