+# ballet
+
+A **light**weight framework for collaborative, open-source data science
+projects through **feat**ure engineering.
+
+- Free software: MIT license
+- Documentation: https://ballet.github.io/ballet
+- Homepage: https://github.com/ballet/ballet
+
+## Overview
+
+Do you develop machine learning models? Do you work by yourself or on a team?
+Do you share notebooks or are you committing code to a shared repository? In
+contrast to successful, massively collaborative, open-source projects like
+the Linux kernel, the Rails framework, Firefox, GNU, or Tensorflow, most
+data science projects are developed by just a handful of people. But think if
+the open-source community could leverage its ingenuity and determination to
+collaboratively develop data science projects to predict the incidence of
+disease in a population, to predict whether vulnerable children will be evicted
+from their homes, or to predict whether learners will drop out of online
+courses.
+
+Our vision is to make collaborative data science possible by making it more
+like open-source software development. Our approach is based on decomposing the
+data science process into modular patches
+that can then be intelligently combined, representing objects like "feature definition",
+"labeling function", or "prediction task definition". Collaborators work in
+parallel to write patches and submit them to a repo. The core Ballet framework
+provides the underlying functionality to merge high-quality contributions,
+collect modules from the file system, and compose the accepted contributions
+into a single product. It also provides [Assemblé](https://github.com/ballet/ballet-assemble), a familiar notebook-based development
+experience that is friendly to data scientists and other inexperienced
+open-source contributors. We don't require any computing infrastructure beyond
+that which is commonly used in open-source software development.
+
+Currently, Ballet focuses on supporting collaboratively developing
+*feature engineering pipelines*, an important part of many data science
+projects. Individual feature definitions are represented as separate Python modules,
+declaring the subset of a dataframe that they operate on and a
+scikit-learn-style learned transformer that extracts feature values from the
+raw data. Ballet collects individual feature definitions and composes them into a
+feature engineering pipeline. At any point, a project built on Ballet can be
+installed for end-to-end feature engineering on new data instances for the
+same problem. How do we ensure the feature engineering pipeline is always
+useful? Ballet thoroughly validates proposed feature definitions for correctness and
+machine learning performance, using an extensive test suite and a novel
+streaming feature definition selection algorithm. Accepted feature definitions can be
+automatically merged by the [Ballet Bot](https://github.com/ballet/ballet-bot) into projects.

+# ballet
+
+A **light**weight framework for collaborative, open-source data science
+projects through **feat**ure engineering.
+
+- Free software: MIT license
+- Documentation: https://ballet.github.io/ballet
+- Homepage: https://github.com/ballet/ballet
+
+## Overview
+
+Do you develop machine learning models? Do you work by yourself or on a team?
+Do you share notebooks or are you committing code to a shared repository? In
+contrast to successful, massively collaborative, open-source projects like
+the Linux kernel, the Rails framework, Firefox, GNU, or Tensorflow, most
+data science projects are developed by just a handful of people. But think if
+the open-source community could leverage its ingenuity and determination to
+collaboratively develop data science projects to predict the incidence of
+disease in a population, to predict whether vulnerable children will be evicted
+from their homes, or to predict whether learners will drop out of online
+courses.
+
+Our vision is to make collaborative data science possible by making it more
+like open-source software development. Our approach is based on decomposing the
+data science process into modular patches
+that can then be intelligently combined, representing objects like "feature definition",
+"labeling function", or "prediction task definition". Collaborators work in
+parallel to write patches and submit them to a repo. The core Ballet framework
+provides the underlying functionality to merge high-quality contributions,
+collect modules from the file system, and compose the accepted contributions
+into a single product. It also provides [Assemblé](https://github.com/ballet/ballet-assemble), a familiar notebook-based development
+experience that is friendly to data scientists and other inexperienced
+open-source contributors. We don't require any computing infrastructure beyond
+that which is commonly used in open-source software development.
+
+Currently, Ballet focuses on supporting collaboratively developing
+*feature engineering pipelines*, an important part of many data science
+projects. Individual feature definitions are represented as separate Python modules,
+declaring the subset of a dataframe that they operate on and a
+scikit-learn-style learned transformer that extracts feature values from the
+raw data. Ballet collects individual feature definitions and composes them into a
+feature engineering pipeline. At any point, a project built on Ballet can be
+installed for end-to-end feature engineering on new data instances for the
+same problem. How do we ensure the feature engineering pipeline is always
+useful? Ballet thoroughly validates proposed feature definitions for correctness and
+machine learning performance, using an extensive test suite and a novel
+streaming feature definition selection algorithm. Accepted feature definitions can be
+automatically merged by the [Ballet Bot](https://github.com/ballet/ballet-bot) into projects.
