介绍在优化设计中的一些常用方法，如遗传算法等(Introduced to optimize the design in some of the commonly used methods, such as genetic algorithms, etc.)

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.

Kelly的Solving Nonlinear Equations with Newton’s Method一书附带的Matlab程序。(The MATLAB codes for the solvers and all the examples accompany this book.I have used the three main solvers nsold.m, nsoli.m, and brsola.m from the collection of MATLAB codes in my own research. The codes were designed for production work on small-to-medium scale problems having at most a few thousand unknowns. Large-scale problems are best done in another language with a high-quality public-domain code.)
