LightGBM, Light Gradient Boosting Machine ========================================= [](https://lightgbm-ci.visualstudio.com/lightgbm-ci/_build/latest?definitionId=1) [](https://ci.appveyor.com/project/guolinke/lightgbm/branch/master) [](https://travis-ci.org/Microsoft/LightGBM) [](https://lightgbm.readthedocs.io/) [](https://github.com/Microsoft/LightGBM/issues) [](https://github.com/Microsoft/LightGBM/blob/master/LICENSE) [](https://pypi.org/project/lightgbm) [](https://pypi.org/project/lightgbm) [](https://gitter.im/Microsoft/LightGBM?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://lightgbm-slack-autojoin.herokuapp.com) LightGBM is a gradient boosting framework that uses tree based learning algorithms. It is designed to be distributed and efficient with the following advantages: - Faster training speed and higher efficiency. - Lower memory usage. - Better accuracy. - Support of parallel and GPU learning. - Capable of handling large-scale data. For further details, please refer to [Features](https://github.com/Microsoft/LightGBM/blob/master/docs/Features.rst). Benefitting from these advantages, LightGBM is being widely-used in many [winning solutions](https://github.com/Microsoft/LightGBM/blob/master/examples/README.md#machine-learning-challenge-winning-solutions) of machine learning competitions. [Comparison experiments](https://github.com/Microsoft/LightGBM/blob/master/docs/Experiments.rst#comparison-experiment) on public datasets show that LightGBM can outperform existing boosting frameworks on both efficiency and accuracy, with significantly lower memory consumption. What's more, [parallel experiments](https://github.com/Microsoft/LightGBM/blob/master/docs/Experiments.rst#parallel-experiment) show that LightGBM can achieve a linear speed-up by using multiple machines for training in specific settings.
