用蒙特卡洛法实现对排队等待问题的计算机模拟 (Monte-Carlo method to realize the problem of computer simulation of waiting)

说明：  基于Matlab的频谱分析,时域抽样定理,FFT的仿真以及应用FFT对典型信号进行频谱分析的方法。 (Matlab-based spectrum analysis, time domain sampling theorem, FFT of the simulation and the application of FFT on the typical signal spectrum analysis.)

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)
