基于云模型的数据挖掘技术

A DATA MINING METHOD BASED ON CLOUD MODEL

定性概念和定量数据之间的转换在空间数据挖掘中起了至关重要的作用.云模型是定性概念和定量描述之间的转换模型,基于云模型,本文提出了在概念空间和特征空间中以不同的层次进行空间数据挖掘的新方法“数据—概念—知识”.

The transforms between qualitative concepts and their quantitative expressions play an important role in spatial data mining. The cloud model of the uncertainty transition between a linguistic term of a qualitative concept and quantitative description. Based on the cloud model, a systematic spatial data mining approach of ＂data - concepts - rules plus exceptions＂ at different hierarchies in both concept space and feature space is proposed.
