空间数据关联规则挖掘的不确定性处理及度量
Uncertainty Processing and Measurement of Spatial Data Association Rules Mining
【摘要】 针对传统空间数据关联规则挖掘缺乏不确定性处理及度量的局限性,将空间数据的不确定性和空间数据挖掘的不确定性有机结合,初步建立了空间数据关联规则挖掘的不确定性处理模型及度量指标,包括空间数据不确定性的Monte Carlo模拟、基于不确定性空间数据的空间自相关度量和关联规则不确定性度量等,并以我国某地区环境调查数据为例进行验证。
【Abstract】 In order to overcome the deficiencies of traditional spatial data association rules mining that is short of uncertainty processing and measurement,the uncertainties of spatial data and spatial data mining were properly combined and uncertainty processing model and measurement indexes of spatial data association rules mining had been founded.In which,four key problems had been probed and analyzed,including uncertainty simulation of spatial data with Monte Carlo methods,measurement of spatial autocorrelation based on uncertain spatial positional data,discreteness of continuous data based on uncertain spatial clustering algorithm and uncertainty measurement of association results.Meanwhile,the experiences concerned were performed using the geo-spatial environment data gotten from one area in China.
