The RandomForestRegressor is a class in the Python scikit-learn library (sklearn) that implements a machine learning algorithm known as Random Forest.
Random Forest is an ensemble learning method that combines multiple decision tree models to make predictions. The RandomForestRegressor specifically is used for regression tasks, where the goal is to predict a continuous target variable.
This algorithm works by creating a collection of decision trees, each trained on a different subset of the training data. During prediction, each tree in the forest independently predicts the target variable, and the final prediction is obtained by averaging or taking the majority vote of the individual tree predictions.
Random Forest Regressor is a popular choice for regression tasks as it provides robustness against overfitting, handles high-dimensional data well, and can capture non-linear relationships between features and the target variable.
The sklearn.ensemble.RandomForestRegressor class in scikit-learn provides various parameters that can be tuned to control the number of trees in the forest, the maximum depth of each tree, and the number of features considered at each split, among others. Additionally, it offers methods to fit the model to training data, make predictions on new data, and evaluate the model's performance.
