Face-recognition-method
基于PCA 和BP 神经网络的人脸识别方法是针对 PCA 方法中存在的高维数问题和它对未训
练过的样本识别率低的缺点而提出的。该方法在预处理的基础上,利用粗糙集对 PCA 降维处理后的人脸特征进行约简,提取其中分类能力强的特征,实现在识别精度不变的情况下,有效的去除冗余信息;然后将约简后的属性输入到神经网络进行规则提取,利用神经网络非线性映射和并行处理的特点,增强对人脸图像识别的泛化能力。实验证明,使用该方法在识别率上有一定的提高(Face recognition method based on PCA and BP Neural Network)

matlab_3_opt
提供一种求解最优哈密尔顿的算法---三边交换调整法,要求在运行jiaohuan3(三交换法)之前,给定邻接矩阵C和节点个数N,结果路径存放于R中。
bianquan.m文件给出了一个参数实例,可在命令窗口中输入bianquan,得到邻接矩阵C和节点个数N以及一个任意给出的路径R,,回车后再输入jiaohuan3,得到了最优解。
由于没有经过大量的实验,又是近似算法,对于网络比较复杂的情况,可以尝试多运行几次jiaohuan3,看是否能到进一步的优化结果。
(Provide an optimal algorithm Hamilton- trilateral exchange Adjustment Act, requiring running jiaohuan3 (c exchange) before a given adjacency matrix C and the node number N, the results of the path stored in the R in. bianquan.m document gives examples of a parameter can be in the command window, type bianquan, be the adjacency matrix C and the node number N and an arbitrary given path R,, carriage return after the input jiaohuan3, have been the optimal solution . After the absence of a large number of experiments, it is approximate algorithm, for more complex network situations, you can try to run several jiaohuan3, can look to further optimize the results.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此,数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分(PID)仿真由相应的离散传函实现,运用数字PID对被控对象实行准确控制。通过调节比例(P)、积分(I)、微分(D),使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)
