SDV | Synthesizes Tabular Data with Statistical Guarantees
SDV
Introduction
SDV (Synthetic Data Vault) is an open-source ecosystem designed for generating synthetic tabular, relational, and time-series data. It allows users to create statistically representative datasets that mimic real-world data without exposing sensitive information, making it ideal for privacy-preserving data sharing, testing, and machine learning development.
Use Cases
Data Privacy & Sharing
Safely share realistic datasets with third parties without compromising sensitive original data.
Software Testing & Development
Generate large, diverse, and robust test datasets for applications and data pipelines.
Machine Learning Model Training
Create synthetic data to augment or replace real data for training and evaluating ML models, especially when real data is scarce or sensitive.
Data Augmentation & Expansion
Expand small or imbalanced datasets to improve the performance and robustness of analytical models.
Research & Education
Provide accessible, non-sensitive, yet realistic datasets for academic studies and educational purposes.
Features & Benefits
Statistical Fidelity
Generates synthetic data that preserves the statistical properties, patterns, and relationships of the original dataset.
Multi-modal Data Support
Handles various data structures including tabular, relational, and time-series data within a unified framework.
