摘　　要：探讨了决策规则的数据约简问题,对条件属性与决策属性在决策表中的概率关联给出了有关结论,推导出基于先验概率的决策规则冗余条件,从而获得基于先验概率的数据约简方法,并用应用实例进行了验证。In this paper the writer discusses the data reduction problem about the decisive rules.Several conclusions have been acquired according to the relation between conditional and decisive properties in decisive table.The writer deduces the redundant condition of decisive rules so that the reduction method has been given based on prior probability.
