A New Evidence Combination Scheme for Decision Assistant
Found in: 2012 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery (CyberC)
By Wanqing Wang,Yongjun Zhao,Jie Huang
Issue Date:October 2012
pp. 53-57
In D-S evidence theory, the Dempster's rule always leads to counter-intuitive results when combining conflicting evidences. The methods proposed to solve these problems all simply focus on BBA features, and ignore the decision assistant purpose. In order t...
Applying Calculus of Variatious to Seek for the Best Impurity Function of Decision Tree
Found in: Electrical and Control Engineering, International Conference on
By Shen Yongjun, Zhao Shulan, Wang Guanghui, Guo Na, Xu Hualong
Issue Date:June 2010
pp. 3389-3390
This study reveals the essence of the impurity function, and the constraints of constructing impurity function is presented. Strategy discussed in this paper makes the method of choosing impurity function become an simple, precise comparison operation from...
Adaptive Calculation of Division Points for Piecewise Linear Transformation and Application in Image Enhancement
Found in: Environmental Science and Information Application Technology, International Conference on
By Junhua Zhang, Gen Yang, Qing Xu, Yongjun Zhao
Issue Date:July 2009
pp. 645-648
Piecewise linear transformation is usually used to increase the contrast of image efficiently. It is most important to select division points during the processing course of piecewise linear transformation because these division points can decide the quali...
Application in Radar Simulation of STK/Connect Module
Found in: Computer Science and Information Engineering, World Congress on
By Junhua Zhang, Gen Yang, Qing Xu, Yongjun Zhao
Issue Date:April 2009
pp. 274-276
Satellite Tool Kit (abbr. STK) is a professional space-analysis software widely used in all phases of a space system’s life cycle. The simulation of STK is efficient and accurate relatively. Sometimes STK can not run efficiently. Maybe some other software ...
