Machine Learning algorithm - Adaboost. Github源码实现 https:/ github.com/csuldw/MachineLearning/tree/master/Adaboost. 自举汇聚法(bootstrap aggregating),也叫做bagging方法，是从原始数据集选择$S$次 有放回的抽取 后得到$S$个新数据集的一种技术。 AdaBoost是adaptive boosting 自适应 boosting 的缩写，其运行过程如下. 从上面两个式子可以看出，$ alpha$和$ epsilon$是成反比的，$ epsilon$越大，$ alpha$就越小，也就是说建立的这个模型应该赋予更少的weight。 DatMat = matrix([ 1. ClassLabels = [ 1.0. Error设为无穷大 对数据及中的每一个特征 第一层循环 对每个步长 第二层循环 对每个不等号 第三层循环 建立一颗单层决策树并利用加权数据集对它进行测试 如果错误率低于 min. DataMatrix,dimen,threshVal,threshIneq).

Computational Learning Theory - VC Dimension | D.W's Notes - Machine Learning
http://www.csuldw.com/2016/08/23/2016-08-23-vc-dimentions
Computational Learning Theory - VC Dimension. Probably Approximately Correct Learnable. Shatter & Break point. 设$X 1, X 2, cdot, X n$为一组独立同分布的随机变量，满足$X i epsilon [a, b], 0 leq i leq n $，$n$为随机变量的个数。 记$n$个随机变量的经验期望 $ bar{X} = frac{X 1 X 2 cdots X n}{n}$，则对于任意的$0 delta 1$, Hoeffding不等式可以表示为:. P( bar{X} - E( bar{X}) geq epsilon ) leq exp left ( frac{-2 n epsilon {2} }{(b-a) {2} right ) tag{1} label{1}$. 在上述式子中，注意到$X i$的取值范围是$[a, b]$，当分类误差为$0-1$损失时，$a$和$b$分别对应到$0$和$1$，此时，方程$ eqref{1}$简化为. So，bad sample发生的概率有...
