YData Synthetic

YData-Synthetic is an open-source package developed in 2020 with the primary goal of educating users about generative models for synthetic data generation. Designed as a collection of models, it was intended for exploratory studies and educational purposes. However, it was not optimized for the quality, performance, and scalability needs typically required by organizations.

!!! note "Update" Even though the journey was fun, and we have learned a lot from the community it is now time to upgrade ydata-synthetic. Heading towards the future of synthetic data generation we recommend users to transition to ydata-sdk, which provides a superior experience with enhanced performance, precision, and ease of use, making it the preferred tool for synthetic data generation and a perfect introduction to Generative AI.

Synthetic data

What is synthetic data?

Synthetic data is artificially generated data that is not collected from real world events. It replicates the statistical components of real data without containing any identifiable information, ensuring individuals' privacy.

Why Synthetic Data?

Synthetic data can be used for many applications:

• Privacy compliance for data-sharing and Machine Learning development
• Remove bias
• Balance datasets
• Augment datasets

Looking for an end-to-end solution to Synthetic Data Generation?
YData Fabric enables the generation of high-quality datasets within a full UI experience, from data preparation to synthetic data generation and evaluation.
Check out the Community Version.

ydata-synthetic to ydata-sdk

With the upcoming update of ydata-syntheticto ydata-sdk, users will now have access to a single API that automatically selects and optimizes the best generative model for their data. This streamlined approach eliminates the need to choose between various models manually, as the API intelligently identifies the optimal model based on the specific dataset and use case.

Instead of having to manually select from models such as:

• GAN
• CGAN (Conditional GAN)
• WGAN (Wasserstein GAN)
• WGAN-GP (Wassertein GAN with Gradient Penalty)
• DRAGAN (Deep Regret Analytic GAN)
• Cramer GAN (Cramer Distance Solution to Biased Wasserstein Gradients)
• CWGAN-GP (Conditional Wassertein GAN with Gradient Penalty)
• CTGAN (Conditional Tabular GAN)
• TimeGAN (specifically for time-series data)
• DoppelGANger (specifically for time-series data)

The new API handles model selection automatically, optimizing for the best performance in fidelity, utility, and privacy. This significantly simplifies the synthetic data generation process, ensuring that users get the highest quality output without the need for manual intervention and tiring hyperparameter tuning.
