Validating synthetic data is crucial for accurate AI evaluation, as it ensures that the artificial data represents the patterns and distributions of real-world data while preserving privacy. Synthetic data is artificially generated information that mimics real-world data's statistical properties and patterns without containing actual original records, and its quality directly impacts downstream AI applications. To validate synthetic datasets, practitioners can apply statistical validation methods, such as comparing distribution characteristics and correlation preservation, as well as machine learning validation approaches, including discriminative testing and comparative model performance analysis. Additionally, implementing effective data corruption measures, establishing clear success criteria and documentation practices, and measuring privacy risk are essential for ensuring the reliability and trustworthiness of synthetic data. By combining these techniques into a comprehensive framework, organizations can create a systematic and reproducible assessment of synthetic data quality, ultimately supporting the development of more accurate and reliable AI systems.
