WebJun 29, 2015 · Decision trees, in particular, classification and regression trees (CARTs), and their cousins, boosted regression trees (BRTs), are well known statistical non-parametric techniques for detecting structure in data. 23 Decision tree models are developed by iteratively determining those variables and their values that split the data … WebApr 9, 2024 · Decision trees use multiple algorithms to decide to split a node into two or more sub-nodes. The creation of sub-nodes increases the homogeneity of the resulting sub-nodes. The decision tree splits the nodes on all available variables and then selects the split which results in the most homogeneous sub-nodes and therefore reduces the impurity.
