To expand on an existing feature\nengineering pipeline, well-structured feature source code submissions can be proposed by contributors and extensively\nvalidated for compatibility and performance.\n\nBallet provides the following functionality:\n- `ballet-quickstart`, a command to generate a new predictive modeling project that uses Ballet framework\n- `Feature` objects, that store feature metadata as well as a robust `DelegatingRobustTransformer` transformer pipeline\n    built alongside the `sklearn_pandas` project.\n- `ballet.eng`, a library of versatile transformers and transformer building blocks for developing features that learn.\n- an extensive feature validation suite, that checks project structure and feature API adherence and runs a streaming\n    logical feature selection algorithm.\n\n*Ballet* is under active development, please [report all\nbugs](https://hdi-project.github.io/ballet/contributing.html#report-bugs).\n\n- Free software: MIT license\n- Documentation: https://hdi-project.github.io/ballet\n- Homepage: https://github.com/HDI-Project/ballet\n\n\n# History\n\n## 0.5 (2018-10-14)\n\n* Add project template and ballet-quickstart command\n* Add project structure checks and feature API checks\n* Implement multi-stage validation routine driver\n\n## 0.4 (2018-09-21)\n\n* Implement `Modeler` for versatile modeling and evaluation\n* Change project name\n\n## 0.3 (2018-04-28)\n\n* Implement `PullRequestFeatureValidator`\n* Add `util.travis`, `util.modutil`, `util.git` util modules\n\n## 0.2\n\n* Implement `ArrayLikeEqualityTestingMixin`\n* Implement `get_contrib_features`\n\n## 0.1\n\n* First release on PyPI\n\n\n",
