摘要
在关联规则评价中引入粗糙相关度的评价指标,构建了"粗糙支持度、粗糙置信度和粗糙相关度"的三维评价模型,对现有的关联规则的粗糙支持度和粗糙置信度的二元评价模型进行了拓展。
Using relevant knowledge of rough set, this paper introduces degree of rough association, then puts forward a kind of three-dimensional Evaluation system for Association Rules, which is composed of rough Support, rough confidence and rough association degree. It expands two-dimensional Evaluation system, which includes rough Support and rough confidence.
