Questions & Step-by-Step Solutions

What is the maximum depth of a Decision Tree?
  • Step 1: Understand what a Decision Tree is. It is a model used for making decisions based on data.
  • Step 2: Learn about 'depth' in a Decision Tree. Depth refers to how many levels the tree has from the top to the bottom.
  • Step 3: Know that a deeper tree can make more complex decisions but may also overfit the data, meaning it might not perform well on new data.
  • Step 4: Realize that we can control the maximum depth of the tree using something called hyperparameters.
  • Step 5: Setting a maximum depth helps to prevent overfitting and makes the model simpler and more general.
