| 摘 要： | 采用二进制粒表示信息系统中的离散化属性值,即对属性进行二进制粒化,定义了基于二进制信息粒的匹配、合取及析取算子,描述了二进制粒属性相关的定义,提出了基于二进制粒的属性相关性判定矩阵的算法,算法通过判定信息系统中属性的相关性,为属性约简及关联规则的求解提供一种新方法.如果相关属性同为条件属性,则可进行约简,选择其一;如果有决策属性,则可生成强关联规则;该算法在气象数据的仿真实验中验证了其实用性. |

| Abstract: | By using the binary granular to show discretization attributes in the information system,this paper makes definitions for the binary granular matching,conjunction and disjunction operators,and the binary granular attribute correlation.This paper also discusses how to determine the matrix based on the binary granular attribute correlation,which is the new way to solve attribute reduction and association rules.If the correlation attribute is also the condition attribute,then reduction can be carried on.If there is the decision attribute,strong association rules are formed.This kind of algorithm is tested in the simulation experiment of meteorological data. |
| Keywords: | binary granularity algorithm operator matching matrix attribute correlation meteorological data |
