Random Forest Regression

Random Forest Regression

Random Forest Regression 

Description

Random Forest Regression is an ensemble learning method that combines multiple decision trees to create a powerful predictive model for continuous target variables. It utilizes random feature selection to improve accuracy.

Why to use

When you want to predict a value depending on single or multiple independent variables.

When to use

  • High accuracy is required
  • Reduced overfitting is required
  • Large Datasets

When not to use

  • Training time is less
  • Less memory

Prerequisites

If the data contains any missing values, use Missing Value Imputation before proceeding with Random Forest Regression.

Input

Any continuous large dataset
