Principal component analysis (PCA) is a popular tool for linear dimensionality reduction and feature extraction. Kernel PCA is the nonlinear form of PCA, which is promising in exposing the more complicated correlation between original high-dimensional features. In this paper, we first talk about the basic ideas of PCA and kernel PCA, and then focus on the reconstruction of pre-images for kernel PCA. We also give an introduction on how PCA is used in active shape models (ASMs), and discuss how kernel PCA can be applied to improve traditional ASMs. Then we show some experiment results to compare the performance of kernel PCA and traditional PCA for pattern classification. We also implement the kernel PCA-based ASMs, and use it to construct human face models.

逻辑回归实现线性分类器，文件中的readme.txt可以看到使用方法。 具体使用就是通过data.txt读入数据（默认2维数据，分为正反两类。）然后用matlab运行solve.m即可得到分类线、分类准确率。(a matlab source code for Logistic Regression. Datas in data.txt are of 2dimension and 2 types. run solve.m in matlab software to get the accuracy and the plot result.)

作为一个功能强大的工具软件，Matlab具有很强的图形处理功能，提供了大量的二维、三维图形函数。由于系统采用面向对象的技术和丰富的矩阵运算，所以在图形处理方面即常方便又高效。(As a powerful software tool, Matlab has a strong graphics capabilities, providing a large number of two-dimensional, three-dimensional graphics functions. Since the system uses object-oriented technology and rich matrix computation, graphics processing, so that is often convenient and efficient.)
