在决策算法中,并不是所有的决策规则都是必要的,一些过剩的决策规则应该消去,而不影响作决策,因此,研究最小化决策规则集的计算方法是很有意义的.传统的决策算法并没有给出最小化决策规则集的形式化计算方法,为了解决最小化决策规则集的形式化计算问题,引入了最小化决策规则可辨识矩阵概念,提供了基于可辨识矩阵的基本决策规则的最小化决策规则集的计算方法

Not all decision rules in existing decisionmaking algorithms are nece ssary. Irrelevant and superfluous decision rules should be eliminated as they do not affect decisionmaking, yet increase computational overhead as well as com p lexity, which can lead to errors. Therefore, research on a method for calculatin g a minimal set of decision rules is very important. But the algorithms currentl y available for decision rules don’t present a formalized method for calculatin g a minimal set of decision rules. To solve this problem, in this paper, a new c oncept of a discernable matrix for minimal decision rules is introduced, and a t heorem for judging a minimal set of decision rules is given. On this basis, we p roposed a formalized calculation method for a minimal decision rules set based o n a discernable matrix. To illustrate this method, an example is presented.
