Once we provide the training data to the RandomForestClassifier model the algorithm selects a bunch of rows randomly with replacement to build the trees. This process is called Bootstrapping (Random replacement)

Randomization as Regularization: A Degrees of Freedom Explanation for Random Forest SuccessRandom forests remain among the most popular off-the-shelf supervised machine learning tools with a well-established track record of predictive accuracy in both regression and classification settings. Despite their ...

1997 (to appear) Relevant Information Paragraph: Car Evaluation Database was derived from a simple hierarchical decision model originally developed for the demonstration of DEX (M. Bohanec, V. Rajkovic: Expert system for decision making. Sistemica 1(1), pp. 145-157, 1990.). The model ...
Random forest has been extensively used as a classifier and regression tool. Its performance has been compared to other ensemble-based and supervised machine learning algorithms, showing that it is one of the top performers [45,46]. It has also been used for vegetation classification and ...
