LightGBM, Light Gradient Boosting Machine

Join the chat at https://gitter.im/Microsoft/LightGBM Build Status GitHubIssues Windows Build status Documentation Status PyPI version

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
  • Parallel and GPU learning supported
  • Capable of handling large-scale data

For more details, please refer to Features.

Experiments on public datasets show that LightGBM can outperform existing boosting frameworks on both efficiency and accuracy, with significantly lower memory consumption. What's more, the experiments show that LightGBM can achieve a linear speed-up by using multiple machines for training in specific settings.
