假设检验例题
7.1 设总体 ,其中参数 , 为未知,试指出下面统计假设中哪些是简单假设,哪些是复合假设:
(1) ; (2) ;
(3) ; (4) ;
(5) .
解:(1)是简单假设,其余位复合假设
(Hypothesis testing for Example 7.1 overall, including parameters, is unknown, pointed out that the following statistical hypothesis test which is a simple assumption, which is a compound hypothesis: (1) (2) (3) (4) (5). Solution : (1) is a simple assumption, the remaining bit composite hypothesis)

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)
