3.1. Results of Random Forest Algorithm 3.1.1. Hyperparameters The entire dataset was trained using the random forest algorithm. The hyperparameters used in this model were n_estimators, max_depth, min_samples_split, min_samples_leaf, and max_features. N_estimators represents the number of tree...
The parameters of the method include the maximum number of trees used, the depth of the trees and the minimum size node to split. 2.2.3. Random forest Random forest is a supervised machine learning technique that can be applied to both classification and regression problems. Random forest is ...
