Questions & Step-by-Step Solutions

What is the primary purpose of using Random Forests in machine learning?
  • Step 1: Understand that Random Forests are a type of machine learning model.
  • Step 2: Know that they are made up of many smaller models called Decision Trees.
  • Step 3: Recognize that each Decision Tree makes its own predictions based on the data.
  • Step 4: Learn that Random Forests combine the predictions of all these Decision Trees.
  • Step 5: Understand that by averaging the predictions, Random Forests can reduce errors.
  • Step 6: Realize that this process helps to improve the overall accuracy of the model.
