Systemically analyzing and summarizing different spatial clustering algorithms that have been published in documents 空间聚类分析是空间数据挖掘的重要研究方向之一。
With the help of spatial clustering analytical tools , not only clustering rules can be extracted in a large column of spatial database , but when combining with other data mining methods knowledge hidden deeply can be discovered efficiently and effectively as well 空间聚类分析既可以发现隐含在海量数据中的聚类规则,又可以与其它数据挖掘方法结合使用,发掘更深层次的知识,从而提高数据挖掘的效率和质量。
The shortcoming of the methods of differential profit and multi - factor comprehensive appraisal is analyzed , and the main thinking and step of gradation by the land price price partition based on spatial clustering is put forward , and an example of shishi city urban land gradation is given 摘要分析了多因素综合评定法、级差收益测算法等城镇土地定级方法的不足,提出了基于空间聚类的地价分区定级法的主要思想和主要步骤,并以石狮市土地定级为例,验证了此方法。
Spatial data mining is one research field of data mining , which can discover effective , novel , invaluable and understandable knowledge or rules from spatial database . clustering is a very important technology and method of data mining as well as spatial clustering analysis is the main research field of spatial data mining 空间数据挖掘是数据挖掘研究的一个重要研究方向,是从空间数据库中识别或提取有效的、新颖的、潜在有用的、最终可理解的模式的非平凡过程。
( 4 ) seven kinds of spatial data clustering approaches are studied . and the technique to solve the problem of constraint - based spatial cluster analysis is explored . in addition , a new spatial clustering algorithm based on genetic algorithms is set forward and it can give attention to local constringency and the whole constringency ( 4 )系统研究了七种典型的空间数据聚类方法,积极探索基于约束条件的空间聚类问题的解决方案;将遗传算法引入空间数据聚类领域,提出一种基于遗传算法的空间聚类算法,该算法兼顾了局部收敛和全局收敛性能。
In the fundamental research part , the paper reorganizes the representative research achievements from the spatial structure and the spatial clusters perspectives , argues that the existing research results about agglomeration mainly focus on the manufacturing industry , lacks exhaustive research about the new agglomeration such as the science and education district and the business district 在理论研究部分,论文从空间结构和空间集群两个角度,对代表性研究成果按研究需要进行了梳理,认为现有研究成果对集聚的讨论主要集中在制造业领域,对科教文化区、商务行政区这样的新集聚缺少细致的研究。
