Forecasting with random forest
WebJul 29, 2024 · Random Forest Classifier A decision tree was used as the predictive model. The model predicts from the subject observations up to the model decision on which the subject’s target value is based. The subject observations are also called branches while subject’s target values are also known as leaves. WebThe number of trees in the forest.
