pip install sklearn 在程序的前面,需要引用sklearn模块: import sklearn 2.决策树sklearn.tree类 机器学习库sklearn中的决策树tree可用于分类决策算法,也可用于回归决策算法。分类决策树的类需要使用DecisionTreeClassifier()方法。 使用时要添加引用语句: from sklearn import tree 3.机器学习算法应用的主要步骤 应...
cumulator.predict_consumptions_f1(dataset, target): Cumulator offers a feature for estimating both the consupmtion and the F1-Score of different classification machine learning algorithms (i.e: Linear, Decision Tree, Random Forest, Neural Network) given the dataset that the user is using. The go...
2.How does Random Forest differ from a simple decision tree? A.Random Forest is less accurate than a single decision tree. B.Random Forest can only be used for regression tasks. C.A single decision tree is trained on the entire dataset, while Random Forest trains multiple trees on various...
