This paper concentrates on two key subroutines of ATR system: Dimensionality reduction and Classifier. After pretreatment on original features a self-organizing neural network trained with the Hebbian rule is used to extract the principal component features. Then a classifier based on Directed Acyclic Graph Support Vector Machines(DAGSVM) is adopted to recognize more than two types of aircraft targets. The experiment results show the proposed method achieves better subset features and higher recognition rate. 2009 IEEE.   CO hydrogenation to C-2-oxygenates over Rh-Mn-Li/SiO2 catalyst: Effects of support pretreatment with nC(1)-C-5 alcohols 期刊论文  OAI收割 catalysis letters, 2008, 卷号: 121, 期号: 3-4, 页码: 241-246 作者:  Jiang, Dahao;  Ding, Yunjie;  Pan, Zhendong;  Chen, Weimiao;  Luo, Hongyuan 收藏  |  浏览/下载：31/0  |  提交时间：2015/11/11 nC(1)-C-5 alcohols  support pretreatment  Rh-based catalyst  C-2-oxygenates  CO hydrogenation   Influence of pretreatment conditions on low-temperature CO oxidation over Au/MOx/Al2O3 catalysts 期刊论文  OAI收割 JOURNAL OF MOLECULAR CATALYSIS A-CHEMICAL, 2003, 卷号: 200, 期号: 1, 页码: 229-238 作者:  Shi, XC;  Wang, DH;  Hao, ZP;  Cheng, DY;  Hu, C   |  收藏  |  浏览/下载：18/0  |  提交时间：2015/11/12 Gold Catalyst  Co Oxidation  Composite Oxide Support  Pretreatment Conditions  Gold Nanoparticle
