classifier random forest

Dec 20, 2017 # Create a random forest Classifier. By convention, clf means 'Classifier' clf = RandomForestClassifier ( n_jobs = 2 , random_state = 0 ) # Train the Classifier to take the training features and learn how they relate # to the training y (the species) clf . fit ( train [ features ], y )

    As the name suggests, Random Forest is a classifier that contains a number of decision trees on various subsets of the given dataset and takes the average to improve the predictive accuracy of that dataset. Instead of relying on one decision tree, the random forest takes the prediction from each tree and based on the majority votes of
