Q: In Random Forests, what does the term 'feature randomness' refer to?
Solution: Feature randomness refers to the practice of randomly selecting a subset of features for each tree in the forest, which helps to create diverse models.
Steps: 5
Step 1: Understand that a Random Forest is made up of many decision trees.
Step 2: Each decision tree in the Random Forest makes decisions based on certain features (or characteristics) of the data.
Step 3: Feature randomness means that instead of using all the features for each tree, we randomly pick a smaller group of features.
Step 4: This random selection of features for each tree helps to ensure that the trees are different from each other.
Step 5: Having diverse trees in the forest improves the overall performance and accuracy of the Random Forest model.
