This paper concentrates on two key subroutines of ATR system: Pre-treatment and design of classifier. In the pre-treatment subroutine  a new method based on Rough Set (RS) is proposed to partition the original sample set into some subsets and calculate their class membership  so that some samples can be chosen by class membership to be trained. After pre-treatment  an iterative algorithm based on Rough Set and Support Vector Machines (IRSSVM) is introduced to design a classifier for recognizing two types of targets. The experiment results show that IRSSVM needs less training time and the classifier is simpler and has more generalization and higher recognition rate. 2010 IEEE.   Research on automatic generalization methods of geographical spatial data - art. no. 675103 会议论文  OAI收割 Geoinformatics 2007: Cartographic Theory and Models, Bellingham Huang, Yongqi; Zhao, Zhui 收藏  |  浏览/下载：26/0  |  提交时间：2014/12/07 spatial scale  multi-scale GIS  dominant cartographic database  automatic generalization   Research on automatic generalization methods of geographical spatial data based on semantic scale - art. no. 67952T 会议论文  OAI收割 Second International Conference on Space Information Technology, Pts 1-3, Bellingham Huang Yongqi; Zhao Zhui; Wu Mengquan; Wu Xiaochun 收藏  |  浏览/下载：15/0  |  提交时间：2014/12/07 scale  ontology  Geoontology  automatic generalization
