LightGBM Transformation Library\n\nThe LightGBM transformation library aims at providing a flexible and automatic way to do feature transformation when using [`LightGBM`](https://github.com/microsoft/LightGBM). Compared to separate transformation. this way has several pros:\n\n- More efficient. Data preprocessing can go with parsing each line, and take advantage of multi-processing designed by lightgbm naturally. No need to store whole transformed data in file/memory.\n- More convenient for development and iteration. Built-in transformation could keep offline and online consistent well by saved/loaded along with model.\n\nIn the repo, user could learn about:\n\n- How to customize favorite parser by playing with LightGBM Parser interface.\n- How to use [`FreeForm2Parser`](./examples/freeform2_parser.cpp), a powerful and efficient tool built in the repo, in model training. Instead of handling data yourself, user just need to prepare a feature spec which contains feature name, transform type and expression, and make slight changes in experiment iterations.\n\n## Get Started and Documentation\n\n- [Installation guide](./docs/Installation-Guide.rst)\n- [Customized parser tutorial](./docs/Customized-Parser-Tutorial.rst)\n- [Transform tutorial](./docs/Transform-Tutorial.rst)\n- [FreeForm2 language spec](./docs/FreeForm2-Language.rst)\n\n## Contributing\n\nThis project welcomes contributions and suggestions.
