Full Changelog: v0.18.0...v0.18.1

v0.18.0

📜 GPU helper script updates + README

v0.18.0 RC1

RC for v0.18.0

⚙️ New model available! DoppelGANger for time series 📈 synthetic data generation!
⚙️ Updates to header clustering logic, added options for isolation batches based on average record length and field complexity
🐞 Bug fixes during record generation and for epsilon calculation when using DP
🔼 Updates to recommended core dependencies, specifically Python 3.9 and TensorFlow 2.8.

New stats and header clustering modules

• 🚀 Adds a new gretel_synthetics.utils module containing stats and header clustering helpers. These modules should be installed via the new utils extra

pip install gretel-synthetics[utils]

• 🧹 Miscellaneous housekeeping and plumbing updates.

v0.16.12

⚙️ Slight performance improvements for TensorFlow and memory footprint reductions

Early Stopping Updates

Enable early stopping for:

• Specified min_delta for the metric used between epochs
• Enable early stopping after a maximum run time

Beta2 Release

🚀 New release to support Gretel Beta2!

Bug fix

🐛 Fixed DataFrame buffering where fields may be missing from a generated record

Record factory updates

⚙️ When using a Record Factory watchdog thread, if the thread throws an exception, cease generating records

Invalid record caching

⚙️ Cache a configurable amount of invalid record details in the RecordFactory which can be accessed and inspected as needed
