Random forest regression is a supervised learning algorithm and bagging technique that uses an ensemble learning method for regression in machine learning. The trees in random forests run in parallel, meaning there is no interaction between these trees while building the trees.

In this article, we will demonstrate the regression case of random forest using sklearn’s RandomForrestRegressor() model. Similarly to my last article, I will begin this article by highlighting some definitions and terms relating to and comprising the backbone of the random forest machine learning.

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.

In this in-depth hands-on guide, we'll build an intuition on how decision trees work, how ensembling boosts individual classifiers and regressors, what random forests are and build a random forest classifier and regressor using Python and Scikit-Learn, through an end-to-end mini-project, and answer a research question.

Une Random Forest (ou Forêt d’arbres de décision en français) est une technique de Machine Learning très populaire auprès des Data Scientists et pour cause : elle présente de nombreux avantages comparé aux autres algorithmes de data.

Random forest can be used on both regression tasks (predict continuous outputs, such as price) or classification tasks (predict categorical or discrete outputs). Here, we will take a deeper look at using random forest for regression predictions.

While Random Forests can handle both classification and regression tasks equally well, we’ll concentrate on the classification part — predicting whether someone will play golf based on weather conditions. The concepts we’ll explore can be easily adapted to regression problems (like predicting number of player) using the same principles.
