https://machinelearningmastery.com/implement-decision-tree-algorithm-scratch-python/中给出了CART(Classification and Regression Trees,分类回归树算法,简称CART)算法的Python实现,采用的数据集为Banknote Dataset,这里在原作者的基础上,进行了略微改动,使其可以直接执行,code如下: 1. # reference: https://machinel...
The algorithm builds a tree in a top-down fashion, starting from a set of rows/objects and a specification of features. At each node of the tree, one feature is tested based on minimizing entropy or maximizing information gain to split the object set. This process is continued until the s...

We used Weka v3.9, StarSpace [26], and Python code with implementations from the Scikit-learn, Keras, and Tensorflow libraries for the classification experiments. The classifiers we employed in Weka were Naïve Bayes, decision tree (J48/C4.5-based decision tree algorithm, Logistic regression (Mu...
