classification of data
相关语句
  数据分类
     In this paper, a theory of knowledge discovery is presented. This theory is based on the simulation of the process of human knowledge discovery, and comprises classification of data, generalization of data in each class against those in other classes, and discovery of implication relation between generated concepts. An implementation of this theory by using an integrated learning called KD_3 is described, and applications of KD_3 to automated construction of knowledge bases for expert systems are outlined.
     本文提出知识发现的一种理论,该理论基于对人类知识发现认识过程的模拟,包括经验数据分类、各类数据的概念抽象、及概念间蕴涵关系的发现等步骤,文中介绍了实现这个理论的一个集成化学习系统KD_3,以及它在自动建立专家系统知识库等方面的应用。

Multi-source information comprehensive mapping method refers to one that chooses aerial and space remote sensing and surface materials for analysis and evaluation under the computersupervised classification of data, and is supplimented by relevant materials and referencesources.This method may employ aerial photographs, as well as SPOT satellite pictures and remote sensing data computer supervised classification graphs, depending...

This method is to draw up 1:100,000 map of land resource evaluation. Multi-source information comprehensive mapping method refers to one that chooses aerial and space remote sensing and surface materials for analysis and evaluation under the computersupervised classification of data, and is supplimented by relevant materials and referencesources.This method may employ aerial photographs, as well as SPOT satellite pictures and remote sensing data computer supervised classification graphs, depending on the demands and possibilities of drawing a land resource evaluation map. For maps of the provincial level, it is proved to be more accurate and convenient to use computer supervised classification of remote sensing data. In order to get the expected result from multi-source, information comprehensive mapping method, it necessary to make good use of the information from computer supervised classification and other relevant remote sensing and non-remote sensing information, solve the components of map delineation in a scientific way, standardize the boundary shape. Finally, field check of the map should be done carefully.1:100,000 map of land resource evaluation compiled by this method has had a check field and has been registered with SPOT satellite pictures and remote sensing data comoputer supervised classification graphs. Its accuracy rates are 88, 91 and 93(%) respectively.
