对于Uplift Tree,类似 分类树可以集成随机森林、GBDT, Uplift Tree 也可以集成 CF(Casual Forest), BART(Bayesian additive regression trees),在很多文献中经常看到此类baseline。 分类模型(The class transformation)思路是通过某种变换,把问题转化为常规的Machine Learning问题解决。在我了解的范围里,业界应用案例不多。
2.1 需要用到的包 主要用到rpart包(Recursive Partitioning and Regression Trees) library(rpart) 没有安装rpart包的先用install.packages("rpart")来安装。 主要用到的函数时rpart(),函数名字和包名字一样,比较好记。 rpart(y ~ ., data = dataset) y~:y代表因变量,~代表=,~右侧时自变量的位置 .:....
对于上面的提到(state,city,street)文档,我们把state映射为X,city映射为Y,street映射为Z。同时我们提供一个函数term2id( ),可以把所有可能的term(这里term就是word的意思)转换成一个整型数值的id,这样每一条docment的记录就能映射到一个3-dimensional的向量坐标,比如通过(term2id(江苏),term2id(南京),term2id(...
8.1 The Basics of Decision Trees 决策树可以用于回归和分类问题。这里我们首先来看看回归问题,再讨论分类问题。 8.1.1 Regression Trees 为了深入展开回归树的讨论,我们从一个简单的例子开始。 Predicting Baseball Players’ Salaries Using Regression Trees 使用回归树预测棒球运动员的薪水 这里我们有一个相关数据库:...
It helps us explore the stucture of a set of data, while developing easy to visualize decision rules for predicting a categorical (classification tree) or continuous (regression tree) outcome. This section briefly describes CART modeling, conditional inference trees, and random forests. CART ...
The results showed that for predicting the risk of CVD, the penalized logistic regression model outperformed the other machine learning approaches, similar to the performance of the SVM model. The KNN and RF models were ranked the next best. Ogunpola et al.27 evaluated seven traditional machine ...

A tree procedure is proposed to check the adequacy of a fitted logistic regression model. The proposed method not only makes natural assessment for the logistic model, but also provides clues to amend its lack-of-fit. The resulting tree-augmented logistic model facilitates a refined model with ...
