VC维理论和结构风险最小化准则是统计学习理论中的重要内容,基于这一理论的支持向量机算法由于具有好的泛化性能受到重视,并被研究用于文本分类问题.基于多项式核的研究工作认为SVM的泛化能力不受多项式阶数的影响,并且能够处理很高维的分类问题,用于文本分类无需进行特征选择.研究发现,随着多项式核阶数的升高,SVM文本分类器会出现过学习现象,并且特征数越多越明显,特征选择是必需的.通过估计函数集的VC维,基于结构风险最小化理论对此问题进行分析,得出的结论跟实验结果相符.

Another-Particle-Swarm-Toolbox
粒子群优化工具箱,采用Matlab编写的PSO程序工具箱(Development Notes for psopt toolbox
Future plans (in no particular order):
* Performance improvement: Automatically check for existence of constraints, skip boundary-checking if unconstrained.
* Performance improvement: Automatically vectorize fitness functions supplied by user, if not already vectorized.
* Performance improvement: Detect and eliminate dependent (i.e. redundant) linear constraints.
* Performance improvement: Automatically choose "penalize" versus "soft" constraint handling method based on type of constraints in problem. If any equality constraints exist, using "penalize", otherwise default to "soft". If "soft", automatically switch to "penalize" if more than a given percentage of particles (initial or interim) are infeasible.
* Feature: An output function defined by options.OutputFcns that can save current swarm state in a file which can be reloaded later as a problem structure, in case of a system crash.
* Feature: Implement multiobjective optimization option)

MFCBandFilter
一个用MFC写的滤波器源代码,代码结构非常精巧,可以参考
功能:1 固定带通滤波
2 可变带通滤波
3 噪声删除
4 输入输出误差计算
实现比较简单,由于使用了Microsoft Foundation classes,代码流程很简单,但是实现的功能比较充分
Filter.h:头文件,定义了CFilterApp 类
Filter.cpp:利用MFC的函数实现了CFilterApp
Filter.rc:资源文件,包括对话框和图标的说明(use a filter to write MFC source code, code structure is very delicate, can be functional : a fixed band-pass filtering two variable bandpass filter to delete four 3 noise input and output error calculation is relatively simple to achieve. As the use of Microsoft Foundation classes, code process is simple, but to achieve the more fully functional Filter.h : The first document, CFilterApp definition of the category Filter.cpp : MFC function realized CFilterApp Filter.rc : resource files, including dialog box and the note icon)
