Question 1

What is the primary purpose of creating synthetic datasets?

  • To avoid collecting data
  • To control variables for testing
  • To increase complexity

πŸ’‘ Hint: Why might you create a dataset instead of just using the real-world data?

Question 2

True or False: Overfitting occurs when a model performs significantly better on training data than on test data.

  • True
  • False

πŸ’‘ Hint: Recall the difference between training performance and unseen data performance.
