What is Decision Trees & Random Forests

Beginner
A decision tree is a supervised learning model that makes predictions by following a series of yes or no questions, and a random forest combines many decision trees to improve accuracy.
Real-world example A bank uses a random forest model to decide whether to approve a loan application based on many combined decision tree predictions.
