In face recognition, Principal Component Analysis (PCA) is often used to extract a low dimensional face representation based on the eigenvector of the face image autocorrelation matrix. Kernel Principal Component Analysis (Kernel PCA) has recently been proposed as a non-linear extension of PCA. While PCA is able to discover and represent linearly embedded manifolds, Kernel PCA can extract low dimensional non-linearly embedded manifolds from data, thus providing a more suitable recognition by a classifier. We provide experimental evidence which show that Kernel PCA performs better than PCA on the ATT Face Dataset when both are used with a lienar Support Vecter Machine Classifier.

在人脸识别中，基于人脸图像自相关矩阵的特征向量，通常采用主成分分析(PCA)来提取低维的人脸表示。核主成分分析(Kernel Principal Component Analysis, PCA)是近年来提出的一种非线性主成分分析方法。PCA能够发现和表示线性嵌入流形，而核PCA能够从数据中提取低维非线性嵌入流形，从而提供更合适的分类器识别。我们提供的实验证据表明，当核主成分分析与线性支持向量机分类器一起使用时，核主成分分析在ATT人脸数据集上的表现优于主成分分析。菲律宾计算机学报1(1)2006 27-30

In this paper, we present a simple linear algorithm for bipartite drawing with minimum edge crossings of complete binary trees. Also obtained with the drawing algorithm is the formula for computing the bipartite crossing numbers of complete binary trees. Philippine Computing Journal 1(1) 2006 1-5
