A new research paper explores the conditions under which classifiers trained on synthetic data can successfully generalize to real-world data distributions. The study derives theoretical bounds for excess error, particularly in scenarios where the real data distribution has mass outside the synthetic data's support. It highlights that without careful validation, models optimized for synthetic data may perform poorly on real data, even with minor distribution shifts. The research suggests that synthetic data should be used in high sample counts and models must be validated on real-world examples to ensure reliable performance. AI
