This release adds support for Python 3.9 and updates dependencies to ensure compatibility with the rest of the SDV ecosystem, and upgrades to the latests RDT release.
- Add support for Python 3.9 - Issue #177 by @pvk-developer
- Add pip check to CI workflows - Issue #174 by @pvk-developer
- Typo in
CTGANcode - Issue #158 by @ori-katz100 and @fealho
Dependency upgrades to ensure compatibility with the rest of the SDV ecosystem.
In this release, the way in which the loss function of the TVAE model was computed has been fixed.
In addition, the default value of the discriminator_decay has been changed to a more optimal
value. Also some improvements to the tests were added.
TVAE: loss function - Issue #143 by @fealho and @DingfanChen- Set
discriminator_decayto1e-6- Pull request #145 by @fealho - Adds unit tests - Pull requests #140 by @fealho
This release exposes all the hyperparameters which the user may find useful for both CTGAN
and TVAE. Also TVAE can now be fitted on datasets that are shorter than the batch
size and drops the last batch only if the data size is not divisible by the batch size.
TVAE: Adaptbatch_sizeto data size - Issue #135 by @fealho and @csalaValueErrorfromvalidate_discre_columnswithuniqueCombinationConstraint- Issue 133 by @fealho and @MLjungg
Maintenance relese to upgrade dependencies to ensure compatibility with the rest of the SDV libraries.
Also add a validation on the CTGAN condition_column and condition_value inputs.
- Validate condition_column and condition_value - Issue #124 by @fealho
- Check discrete_columns valid before fitting - Issue #35 by @fealho
- ValueError: max() arg is an empty sequence - Issue #115 by @fealho
In this release we add a new TVAE model which was presented in the original CTGAN paper. It also exposes more hyperparameters and moves epochs and log_frequency from fit to the constructor.
A new verbose argument has been added to optionally disable unnecessary printing, and a new hyperparameter
called discriminator_steps has been added to CTGAN to control the number of optimization steps performed
in the discriminator for each generator epoch.
The code has also been reorganized and cleaned up for better readability and interpretability.

In this release we introduce several minor improvements to make CTGAN more versatile and propertly support new types of data, such as categorical NaN values, as well as conditional sampling and features to save and load models.
Additionally, the dependency ranges and python versions have been updated to support up to date runtimes.
