2.0 Release to celebrate progress and code cleanup
Enough incremental improvements have added up that we're now ready to mark a 2.0 release!
Part of the progress also means deprecating a few unused features that were adding unnecessary complexity and preventing us from implementing new features like ensembling properly.
New changes for the 2.0 release:
- Refactored and cleaned up code. Ensembling should now be much easier to add in, and in a way that's fast enough to be used in production (getting predictions from 10 models should take less than 10x as long as getting predictions from 1 model)
- Deprecated compute_power
- Deprecated several methods for grid searching over transformation_pipeline hyperparameters (different methods for feature selection, whether or not to do feature scaling, etc.). We just directly made a decision to prioritize the final model hyperparameter search.
- Deprecated the current implementation of ensembling. It was implemented in such a way that it was not quick enough to make predictions in prod, and thus, did not meet the primary use cases of this project. Part of removing it allows us to reimplement ensembling in a way that is prod-ready.
- Deprecated X_test and y_test, except for working with calibrate_final_model.
- Added better documentation on features that were in silent alpha release previously.
- Improved test coverage!
Major changes since the 1.0 release:
- Integrations for deep learning (using TensorFlow and Keras)
- Integration of Microsoft's LightGBM, which appears to be a possibly better version of XGBoost
- Quite a bit more user logging, warning, and input validation/input cleaning
- Quite a few edge case bug fixes and minor performance improvements
- Fully automated test suite with decent test coverage!
- Better documentation
- Support for pandas DataFrames- much more space efficient than lists of dictionaries
