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。
Systems and methods of updating a multi-level data structure for controlling an agent. The method may include: accessing a data structure defining one or more nodes. A non-leaf node of the one or more nodes may be associated with one or more edges for traversing to a subsequent node. An...
Only studies based on statistical methods for ozone estimation in China were chosen for comparison with our study (Table S9). The DF model had a better performance than most previous models, such as the GWR model (0.25° × 0.25°, sample-based CV R2 = 0.77; Zang et al., 2021), the...
In this paper, two novel hybrid decision tree-based machine learning models are proposed to obtain more accurate short-term water quality prediction results. The basic models of the two hybrid models are extreme gradient boosting (XGBoost) and random forest (RF), which respectively introduce an ...

We also comment on the tradeoff between the predictive power of ensemble methods and the interpretive value of their single-tree counterparts. The chapter concludes with a discussion of tree-based methods in the broader context of supervised learning techniques. In particular, we compare classification...
