中文摘要 |
在随机信息系统中,根据不可辨识关系,提出了不可辨识属性矩阵的概念。讨论了不可辨识属性矩阵与可辨识属性矩阵的关系,根据证据理论,给出了基于不可辨识属性矩阵的约简算法。相对于可辨识属性矩阵算法,该算法在时间和存储空间花费上都有较大的改善和提高。 |
英文摘要 |
In random information system, according to the indiscernibility relation, the concept of indiscernibility attribute matrix is proposed, and the relation between discernibility attribute matrix and indiscernibility attribute matrix is discussed. According to the evidence theory, a reduction algorithm based on indiscernibility attribute matrix is introduced. Compared with discernibility attribute matrix algorithm, the algorithm greatly reduces running time and memory space. |
