A random forest is a meta estimator that fits a number of decision tree classifiers on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.
A random forest is a meta estimator that fits a number of decision tree regressors on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.

5 de ene. de 2022 · Random forests are an ensemble machine learning algorithm that uses multiple decision trees to vote on the most common classification; Random forests aim to address the issue of overfitting that a single tree may exhibit; Random forests require all data to be numeric and non-missing
24 de feb. de 2021 · A random forest—as the name suggests—consists of multiple decision trees each of which outputs a prediction. When performing a classification task, each decision tree in the random forest votes for one of the classes to which the input belongs.
