It classifies data of conflict , redundancy and complementarity according to the relationship of self - entropy and mutual entropy about sensor data , and builds the structure of multisensor data classification for classified fusion 该方法根据传感器数据自熵和互熵的关系实现冲突、冗余和补充的数据分类，建立多传感器数据分类结构并进行分类融合。
Based on that , furthermore , the concept and logic of the database was designed . after classifying and coding of the data , a spatial database including such data types as text , figures and tables was built 以此为依据，进一步进行数据库的概念与逻辑设计，经过数据分类、编码等的处理，建立了一个包括图形、文本、表格等数据类型的空间数据库。
The theories and methods for high dimensional multispectral data classification with limited training samples are studied , which are parts of important research contents of national 863 hi - tech , 973 project and ministry of education phd fund 结合国家863计划项目、国防973项目和教育部博士点基金项目，研究了有限样本下基于机器学习的高维多光谱数据分类问题。
With the rough sets theory , people can process the undistinguished problem using uncompleted information or knowledge . and also enhance the capability to classify the imprecise data coming from observation or measurement 粗糙集理论反映了人们以不完全信息或知识去处理一些不可分辨现象的能力，或依据观察、度量得到某些不精确的结果而进行数据分类的能力。
Data classification , as an important aspect of research of dm , now has been successfully applied to medical diagnosis , weather prediction , credit approval , customer segmentation , fraud detection and so on 数据分类方法作为数据挖掘的一个重要方面，在统计、机器学习、神经网络、专家系统等领域中有着广泛的应用，如医疗诊断、天气预测、信用证实、顾客区分、欺诈甄别等。
Secondly , we analyse general criteria of data classification , the definition and representation method of conceptual hierarchy , and criteria of evaluating classification scheme . according to the analysis , we briefly provede the architecture of data classifier 而后，分析了数据分类的一般标准、概念层次的定义和表示方法、评价分类模式的标准等问题，并给出了数据分类器的结构框架。
The spatial classification module can classify the geographic objects according to a pre - specified attribute , and the classification result can be used to provide decision support . the classification result can be saved to and loaded from an xml file 空间数据分类模块能够对地理对象按照某个属性分类，利用分类结果为决策者提供决策支持，挖掘结果可以保存在xml文件中或者从文件中读取。
