Description:

xgboost: eXtreme Gradient Boosting

This is yet another gradient boosting (tree) (GBRT) library.

The implementation is based on C++, optimized for memory and efficiency, to try target large data with a single machine.

Palatalization is done with OpenMP. The algorithm relies on sparse feature format, which means it naturally handles missing values.

Supported key components so far:

  • Gradient boosting models:

    • regression tree (GBRT)

    • linear model/lasso

  • Objectives to support tasks:

    • regression

    • classification

    • rank

  • OpenMP implementation

Changes to previous version:

New features: - Python interface - New objectives: weighted training, pairwise rank, multiclass softmax - Comes with example script on Kaggle Higgs competition, 20 times faster than skilearn's GBRT
