基于 Apriori 算法的点线关联模式在地震空间数据挖掘中的应用

摘要

该文根据对地震空间数据中的两种数据类型，点要素类型、线要素类型进行分析，基于 Api-rori 算法，提出一种分析地震空间数据的线－点关联规则的数据挖掘算法，对算法进行了描述，并以中国云南省地区发生的地震空间数据作为主要数据来源进行了算法的实验，由于 Apriori 算法是一种基于概率的挖掘算法，通过算法可以得出云南省地区地震空间数据库线－点数据所蕴含的概率关系，并为进一步进行空间概率分析及推理有一定的意义。%The analysis in this paper is based on two data types of spatial data of earthquake,i.e.point feature and line feature.According to Apriori algorithm,a point -line association pattern was used in the spatial data mining of earthquake.This pattern was described and then verified by the earthquake spatial data in Yunnan province.As Apriori algorithm is on the basis of probability,the probabilistic relations in the point -line data of earthquake spatial data in Yunnan province can be obtained,thus enjoying some significance in the further anal-ysis and reasoning of spatial probability.
