Random Forest Regression

Random Forest regression is a machine learning technique that utilizes an ensemble of decision trees to perform regression tasks. It is an extension of the Random Forest algorithm, which is primarily used for classification problems. Random Forest regression is designed to predict continuous numerical values rather than discrete classes.
