PCA_NN
- PCA(主成分分析)算法被广泛应用于工程和科学研究中,本报告主要从PCA的基本结构和基本原理对其进行研究,常规的PCA算法主要采用线性算法,通过研究论证发现线性的PCA算法存在着许多不足,比如线性PCA算法不能从线性组合中把独立信号成分分离出来,主分量只由数据的二阶统计量—自相关阵确定,这种二阶统计量只能描述平稳的高斯分布等,因此必须对其进行改进,经改进后的PCA算法有非线性PCA算法、鲁棒算法等。我们通过PCA算法在直线(平面)中拟和的例子说明了PCA在工程中的应用。本例子采用的是成分分析中的

- 现有的代数特征的抽取方法绝大多数采用一维的方法,即首先将图像转换为一维向量,再用主分量分析(PCA),Fisher线性鉴别分析(LDA),Fisherfaces式核主分量分析(KPCA)等方法抽取特征,然后用适合的分类器分类。针对一维方法维数过高,计算量大,协方差矩阵常常是奇异矩阵等不足,提出了二维的图像特征抽取方法,计算量小,协方差矩阵一般是可逆的,且识别率较高。-existing algebra feature extraction method using a majority of th
