What is SDV?
SDV is a Python library that learns the patterns in real data using several machine learning algorithms and reproduces them as synthetic data. It can generate data for single tables, multiple connected tables, and sequential (time-series) tables. It compares and evaluates synthetic data against real data, produces quality reports, and lets you define anonymization methods and business rules (constraints). It is offered as the free SDV Community, the paid SDV Enterprise, and add-on packages (Bundles).
- Synthetic data generation for single tables, multiple (relational) tables, and sequential (time-series) tables
- Multiple models, from statistical models like GaussianCopula to deep learning models like CTGAN
- Comparative evaluation of synthetic and real data, and quality reports
- Preprocessing, anonymization, and logical constraint definition
- Applying complex rules across multiple tables (Constraint Augmented Generation, bundle)
- Differentially private synthetic data (bundle)
- AI Connectors with direct database integration (metadata, import, export)
- Synthetic data evaluation (SDMetrics) and generator benchmarking (SDGym)
Who uses SDV and for what
- Development teams test software with realistic test data
- Making up for a shortage of data for training AI models
- Sharing data externally using synthetic data instead of real data
