Questions & Step-by-Step Solutions
In a Random Forest, what is the purpose of using multiple Decision Trees?
Step 1: Understand what a Decision Tree is. A Decision Tree is a model that makes decisions based on asking a series of questions about the data.
Step 2: Recognize that a single Decision Tree can sometimes make mistakes, especially if it learns too much from the training data (this is called overfitting).
Step 3: Learn that a Random Forest is a collection of many Decision Trees working together.
Step 4: Realize that by using multiple Decision Trees, the Random Forest can average their predictions, which helps to correct individual mistakes.
Step 5: Understand that this averaging process makes the model more reliable and accurate, leading to better performance on new data.
