4 . it analyses simulation data in search of parameters which can delegate pattern information , extracts ten parameters in order to distinguish pattern effectively , simply , fast and exactly . 5 对不同流型的仿真数据进行统计分析，寻找能代表流型特征的各种参数，提取出10种特征参数为高效，简单、快捷、准确的流型辨识打下基础。
Firstly , the four features of five air targets are extracted here : target identity ( tid ) , elevation measurement , target speed and acceleration . then the statistical models of features are established to classify five air targets 首先，就五类空中目标提取了四种特征：目标身份、俯仰角、速度和加速度等，同时建立了它们的统计模型。
Optimize sofm learning algorithm , then study single neural net classifer based on optimized sofm learning algorithm which takes rough grid and direction - line as input . and use the single classifer on the figure letter and province recognition 采用这种优化的算法，对分别使用上面两种特征作为输入的sofm单一分类器进行数字、字母和省份汉字的识别研究。
We also have proved that these three cardinal functions are isomorphic invariable . particularly , character is equivalent invariable . after this main topic , the characterization and definition of meet - continuous complete semi - lattices are given 第节定义了连续domain的特征并讨论了三种特征之间的关系，得到了连续domain的特征与zp的特征相等
The state shall guarantee the teachers " lawful rights and interests . the life - long employment is possible for the excellent teachers and the school principals ca n ' t discharge the teachers unless they violate the provisions written in education law 因此，教师是以聘任的方式从事国家法律规定的教育公务，具有公务雇佣地位，即在身份上兼具有公务员和雇员两种特征。
16 phillips p j , wechsler h , huang j , rauss p j . the feret database and evaluation procedure for face - recognition algorithms . image and vision computing , 1998 , 16 : 295 - 306 . 17 martinez a m , benavente r . the ar face database 在这一框架下，人脸图像中所有可能的区域都被看作某种特征，这样就可以通过某种选择机制选择出若干个这种特征，继而集成起来以获得更好的识别效果。
It is demonstrated by simulation data . as for classifier , it presents the artificial neural network . based on three methods of modulation recognition and decision tree classifier and neural network classifier , experimentations have been carried through 在分类器设计方面,介绍了利用神经网络进行模式识别的原理,采用前述的三种特征提取方法,分别结合判决树分类器和神经网络分类器对信号进行分类,并且进行了试验论证。
