Google Cloud Professional Data Engineer — Question 11

You are training a spam classifier. You notice that you are overfitting the training data. Which three actions can you take to resolve this problem? (Choose three.)

Answer options

• A. Get more training examples
• B. Reduce the number of training examples
• C. Use a smaller set of features
• D. Use a larger set of features
• E. Increase the regularization parameters
• F. Decrease the regularization parameters

Correct answer: A, C, E

Explanation

The correct actions to mitigate overfitting are to get more training examples, use a smaller set of features, and increase the regularization parameters. More training data can help the model generalize better, while reducing features can simplify the model. Increasing regularization parameters helps prevent the model from fitting too closely to the training data, unlike decreasing them, which would exacerbate overfitting.
