So feature selection become usually necessary to reduce dimensionality of the combination of multi-sensor features and improve system performance in system design. In general  there are two main missions. One is improving the recognition correct rate as soon as possible  the optimization is usually applied to feature selection because of its computational feasibility and validity. For further improving recognition accuracy and reducing selected feature dimensions  this paper presents a more rational and accurate optimization  Bidirectional Binary Particle Swarm Optimization (BBPSO) algorithm for feature selection in feature-level fusion target recognition system. In addition  we introduce a new evaluating function as criterion function in BBPSO feature selection method. At the last  we utilized Leave-One-Out method to validate the proposed method. The experiment results show that the proposed algorithm improves classification accuracy by two percentage points  while the selected feature dimensions are less one dimension than original Particle Swarm Optimization approach with 16 original feature dimensions. 2009 IEEE.   Analysis of narrow ridge estimation for linear CCD RFM model and its application 会议论文  OAI收割 2009 IEEE International Geoscience and Remote Sensing Symposium, IGARSS 2009,, Cape Town, South africa, July 12, 2009 - July 17,2009 Yan, Dongmei; Kou, Tianyou; Wang, Fenfei; Chen, Fen 收藏  |  浏览/下载：18/0  |  提交时间：2014/12/07 Rational functions  Computation theory  Estimation  Function evaluation  Geology  Remote sensing   An extended subequation rational expansion method with symbolic computation and solutions of the nonlinear Schrodinger equation model 期刊论文  OAI收割 NONLINEAR ANALYSIS-HYBRID SYSTEMS, 2008, 卷号: 2, 期号: 2, 页码: 242-255 作者:  Chen, Yong;  Li, Biao   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/07/30 Subequation rational expansion method  Schrodinger equation  Like-solitons  Like-periodic function solution   A Method to Improve Geometric Correction Accuracy for multi-angle Data 会议论文  OAI收割 Itess: 2008 Proceedings of Information Technology and Environmental System Sciences, Pt 2, Beijing Wang, Dianzhong; Fu, Anmin; Zhang, Zhiyu; Pang, Yong; Guo, Zhifeng 收藏  |  浏览/下载：19/0  |  提交时间：2014/12/07 CHRIS  ortho-rectify  rigorous sensor model  rational function model  (RFM)   Application of rational function approximation technique to hybrid fe/bi/mlfma for 3d scattering 期刊论文  iSwitch采集 International journal of rf and microwave computer-aided engineering, 2007, 卷号: 17, 期号: 6, 页码: 521-532 作者:  Peng, Zhen;  Sheng, Xin-Qing 收藏  |  浏览/下载：23/0  |  提交时间：2019/05/10 Hybrid fe/bi/mlfma  Rational function approximation  Asymptotic waveform evaluation (awe)  Model-based parameter estimation (mbpe)  Electromagnetic scattering
