This dissertation proposes the c - dma ( center - distributed mining association rules ) algorithm in star structure , and a method of mining multiple layers association rules in distributed databases , a method of mining multiple layers association rules using meta - learning and adjustable method in distributed databases , based on analyses and introduction of the basic concepts and algorithms of mining association rules and mining association rules in distributed databases . after analyzing the quantitative association rules and interestingness of association rules which are encountered often in distributed association rule mining , the dissertation proposes the methods of changing the quantitative attributions into bool attributions using fcm and gene algorithm 本文在分析和介绍了关联规则挖掘的基本概念和方法以及分布式关联规则挖掘方法和技术基础上,提出了中心结点结构的分布式关联规则挖掘的算法( c - dma ) ,分布式多层概念的关联规则挖掘算法,以及分布式元学习可变精度关联规则的挖掘算法;并且,在分析和研究了分布式关联规则挖掘中常见的数量型关联规则、关联规则的兴趣度问题的基础上提出了数量关联规则的聚类划分方法以及兴趣度过滤方法。
One is to store the dual network of road network with the forward star structure , which is a compact network storage structure satisfying the needs of route planning . the other one is to straight store road network with the generalized forward star structure , which can represent turn restrictions and inter section delays 一种是采用满足路线优化需要的紧凑的路网存储结构? ?前向关联边结构存储路网的对偶网络;另一种是利用能够表达交叉口转向限制和交叉口延误的存储结构? ?扩展的前向关联边结构,直接存储路网。
Thirdly , we need to build up database to keep the data for data mining , and based on the analysis of economic data warehouse , data table and the problems of data granularity , data partition and the structure of data warehouse , we set the star structure of regional macro economic analysis , and we design the fact table and dimension table for data warehouse . so we design and construct economic data warehouse and fulfill economic data entry , transfer , store and management 在这章中我们给出了一个关于pse的数据仓库属性的定义,即:数据仓库是一种来源于各种渠道的单一的、完整的、稳定的、集成的数据存储,这个储存的数据本质上是面向主题的、集成的、非易失的和可动态更新的,数据的逻辑形式是提供公式数据和组织数据。
