Questions & Step-by-Step Solutions

What is a key characteristic of ensemble methods like Random Forests?
  • Step 1: Understand that ensemble methods are techniques that use multiple models together.
  • Step 2: Learn that Random Forests is a type of ensemble method that uses many decision trees.
  • Step 3: Know that the main idea is to combine the predictions from all these trees.
  • Step 4: Realize that by combining models, ensemble methods can make better predictions than a single model.
  • Step 5: Remember that this combination helps to reduce errors and improve the reliability of the results.
