| 摘 要： | 本文介绍了粒计算及粗糙集的基本概念,通过对粒计算下的粗糙集模型中两种属性约简算法分析对比,提出结合两种属性约简方法,即用差别矩阵求得核属性后,将属性重要性作为启发信息继续进行属性约简,可取得合理的属性组合,并将该方法应用于农业气象数据,挖掘出了合理的可进行预测的规则集。

| Abstract: | Introducing the base-conception of granular computing and rough set,puts forward combining both attribute reduction arithmetic through analysis and contrast the attribute reduction arithmetics in rough set model of granular computing .Concretely taking core attributes by indistinguishable matrix,then use it for heuristic information to next reduction,gained rational attribute set finally,and applied in weather data to mining rational and useful rules. |

| Keywords: | granular computing rough set attribute reduction weather data |
