When Can Matrix Query Languages Discern Matrices?
, 2020 We investigate when two graphs, represented by their adjacency matrices, can be distinguished by means of sentences formed in MATLANG, a matrix query language which supports a number of elementary linear algebra operators. When undirected graphs are concerned, and hence the adjacency matrices are real and symmetric, precise characterisations are in ...

Attribute Reduction Algorithm of Discernibility Matrix Based on Compatibility Relation
, 2005 为有效处理灰色信息系统的属性约简问题,将粗糙集理论中有关属性约简的方法运用到灰色信息系统中,提出了一种基于容差关系的辨识矩阵属性约简法.这种方法并不对灰数进行白化,而是直接利用灰数的区间覆盖性定义一个基于贴近度的容差关系,并根据这个容差关系建立一个辨识矩阵对属性进行约简,避免了当灰数的取值分布信息缺乏时对灰数进行白化的主观性,是一种较为客观有效的灰色信息系统的属性约简法.An attribute reduction of discernibility matrix was proposed to do ...
