基于属性约简的混凝土抗冻性挖掘方法

粗糙集中的属性约简是在保持信息库分类能力不变的条件下,通过删除其中不相关或不重要的属性得到的条件属性集合。影响混凝土抗冻性的主要因素有外加济、含气量、骨料、水灰比和坍落度等。文章主要利用属性约简算法,对混凝土的抗冻性进行决策性挖掘。

Data Mining Method for Concrete Frost Resistance Based on Attribute Reduction

Attribute reduction is to remove the irrelevant or unimportant knowledge in the rough set on the condition of remaining the classification ability of the data set.The major factors affect the frost resistance of concrete are admixtures,air content,aggregate,water-cement ratio,slump and so on.In this paper,a decisive data mining on the frost resistance of concrete is performed using attribute reduction.
