  3. Decision Tree

  4. Support Vector Machine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Random Forests are constructed by combining multiple decision trees. Each decision tree is trained on a different subset of the data and makes predictions independently.

Multiple choice

Which technique is used in Random Forests to reduce the variance of the individual decision trees?

  1. Bagging

  2. Boosting

  3. Stacking

  4. Voting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Random Forests utilize bagging (bootstrap aggregating) to reduce variance. In bagging, multiple subsets of the training data are created, and a decision tree is trained on each subset. The final prediction is made by combining the predictions from all the individual trees.

Multiple choice

How does the number of trees in a Random Forest impact its performance?

  1. Decreased Computational Cost

  2. Reduced Overfitting

  3. Diminished Generalization Performance

  4. Increased Variance

  1. Early Stopping

  2. Dropout

  3. Regularization

  4. Cross-Validation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cross-validation is commonly used to prevent overfitting in Random Forests. It involves dividing the data into multiple folds, training the model on different combinations of folds, and evaluating its performance on the held-out fold.

Multiple choice

How does Random Forests handle categorical features?

  1. One-Hot Encoding

  2. Label Encoding

  3. Dummy Encoding

  4. Hashing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Random Forests typically handle categorical features using one-hot encoding. In one-hot encoding, each unique category is represented by a separate binary feature. This approach allows the model to learn the relationships between categorical features and the target variable effectively.
