YData Synthetic
A package to generate synthetic tabular and time-series data leveraging the state of the art generative models.
🎊 The exciting features:
These are must try features when it comes to synthetic data generation:
- A new streamlit app that delivers the synthetic data generation experience with a UI interface. A low code experience for the quick generation of synthetic data
- A new fast synthetic data generation model based on Gaussian Mixture. So you can quickstart in the world of synthetic data generation without the need for a GPU.
- A conditional architecture for tabular data: CTGAN, which will make the process of synthetic data generation easier and with higher quality!
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
This repository contains material related with architectures and models for synthetic data, from Generative Adversarial Networks (GANs) to Gaussian Mixtures. The repo includes a full ecosystem for synthetic data generation, that includes different models for the generation of synthetic structure data and time-series. All the Deep Learning models are implemented leveraging Tensorflow 2.0. Several example Jupyter Notebooks and Python scripts are included, to show how to use the different architectures.
Are you ready to learn more about synthetic data and the bext-practices for synthetic data generation?
Quickstart
The source code is currently hosted on GitHub at: https://github.com/ydataai/ydata-synthetic
Binary installers for the latest released version are available at the Python Package Index (PyPI).
pip install ydata-synthetic
The UI guide for synthetic data generation
YData synthetic has now a UI interface to guide you through the steps and inputs to generate structure tabular data. The streamlit app is available form v1.0.0 onwards, and supports the following flows:
- Train a synthesizer model
- Generate & profile synthetic data samples
Installation
pip install ydata-synthetic[streamlit]
Quickstart
Use the code snippet below in a python file (Jupyter Notebooks are not supported):
from ydata_synthetic import streamlit_app
streamlit_app.run()Or use the file streamlit_app.py that can be found in the examples folder.
python -m streamlit_app
The below models are supported:
- CGAN
- WGAN
- WGANGP
- DRAGAN
- CRAMER
- CTGAN
Examples
Here you can find usage examples of the package and models to synthesize tabular data.
- Fast tabular data synthesis on adult census income dataset
- Tabular synthetic data generation with CTGAN on adult census income dataset
- Time Series synthetic data generation with TimeGAN on stock dataset
- More examples are continuously added and can be found in
/examplesdirectory.
