用来回归的树(Regression Tree)和用来分类的树(classification Tree)具有一定的相似性,不过其不同之处在于决定分裂(Split)的过程。 使用某些技术(Ensemble Methods),可以构建多个Decision Tree: Bagging Decision Tree:创建多个Decision Tree,通过替换训练集合,得到多个Decision Tree,最终得到一致的结果。 Random Forest Clas...

在weka中有信息增益weka.attributeSelection.InfoGainAttributeEval和信息增益率weka.attributeSelection.GainRatioAttributeEval的实现,可以看下实现原理。 Regression Tree的建树过程。 对于回归树,没有分类数据,只有根据观察数据得出的值,注意观察值取值是连续,在这种情况下Classification Tree的最优划分规则就无能为力。 在...
