首先给出了基于一一映射的概念格不同类型属性的等价刻画定理,在此基础上得到了一种新颖的概念格属性约简算法;最后通过实例表明了该约简算法的可行性与有效性。
First,from the viewpoint of one-one mapping,this paper gave the theory of measuring the characteristic of diffenent attributes equivalently,and then proposed a novel algorithm to find attribute reduction of concept lattices.At last,it used a real example to demonstrate both its feasibility and effectiveness,respectively.
