Webb8 aug. 2024 · Sadrach Pierre Aug 08, 2024. Random forest is a flexible, easy-to-use machine learning algorithm that produces, even without hyper-parameter tuning, a great result most of the time. It is also one of the most-used algorithms, due to its simplicity and diversity (it can be used for both classification and regression tasks). WebbRandom forests is a classifier that combines a large number of decision trees. The decisions of each tree are then combined to make the final classification. This “team of specialists” approach random forests take often outperforms the “single generalist” approach of decision trees. Multiple overfitting classifiers are put together to ...
