Questions & Step-by-Step Solutions

What is a key feature of Random Forests that enhances their robustness?
  • Step 1: Understand that Random Forests are a type of machine learning model used for classification and regression.
  • Step 2: Learn that they consist of many individual decision trees.
  • Step 3: Know that each decision tree is built using a random sample of the data.
  • Step 4: This random sampling is called 'bootstrap aggregating' or 'bagging'.
  • Step 5: Bagging helps to create diverse trees, which means they make different predictions.
  • Step 6: When you combine the predictions from all these trees, it reduces errors and makes the model more stable.
  • Step 7: This process of combining predictions from multiple trees enhances the robustness of the Random Forest model.
