我们需要成百上千的分类器来解决现实世界的分类吗 我们评估179分类17种分类器（判别分析，贝叶斯，神经网络，支持向量机，决策树，基于规则的分类器，升压、装袋、堆放、随机森林和其他合奏，广义线性模型，线性，偏最小二乘法和主成分回归，logistic回归、多项式回归、多元自适应回归样条等方法），实现在WEKA，R（有或没有插入包），C和Matlab，包括所有目前可用的相关分类。(Do-we-Need-Hundreds-of-Classifiers-to-Solve-Real-World-ClassificationProblems)

牛顿插值和Neville插值、Taylor解常微分方程小程序供大家学习。(Newton Interpolation and Neville interpolation, Taylor, Xie Ordinary Differential Equations applet for everyone to learn.)

本程序是用节点导纳矩阵计算三相短路电流 输入数据--形成节点阻抗矩阵--选择故障点---计算短路电流----计算个节点电压---计算指定支路的电流(this procedure is used node admittance matrix calculation of three-phase short-circuit current input data-- forming node impedance matrix-- election Optional fault--- calculation of short-circuit current-voltage computing nodes designated calculated slip road--- Electricity)

说明：  上数据挖掘课的课件，是EM算法的，其中还包括最大似然值，最大似然估计，以及cluster(data mining,EM Algorithm ,Likelihood, Mixture Models and Clustering )

相场法基础书籍的配套计算代码，对于学习相场法的基础同学来说极其有用(The supporting calculation code of the phase field basic book is extremely useful for the students who are studying the basic method of the phase field method.)

说明：  SIRP法仿真K分布杂波，之前有下载过类似的，但是建立非线性表时的函数定义是有错误的，进行了修改，可以得到较好的估计效果(Simulating K distribution clutter by SIRP, similar to the code which been downloaded before, but when the establishment of non-linear function is wrong and modified, you can get a better estimate effect )

说明：  能够实现线性回归,里面有一个线性回归的实例(It can realize linear regression. There is an example of linear regression)

ABAQUS的二次开发，非常适合学习VDLOAD的同志们学习，来自廖公云老师的《ABAQUS有限元软件在道路工程中的应用》(Learning from Liao Gongyun teacher "ABAQUS finite element software ABAQUS secondary development, very for learning VDLOAD, comrades in road works")

说明：  分子动力学模拟的简化版。PDF文件中包含了伪代码。(a simple example for molecular dynamics)

EnKF集合卡尔曼滤波代码，用于读写模式集合，包括两种扰动观测分析方案。(These files illustrate the model used for storing, reading and writing the ensemble of model states.)
