|
|
An optimized general purpose gradient boosting library. The library is parallelized, and also provides an optimized distributed version.
|
|
It implements machine learning algorithms under the [Gradient Boosting](https://en.wikipedia.org/wiki/Gradient_boosting) framework, including [Generalized Linear Model](https://en.wikipedia.org/wiki/Generalized_linear_model) (GLM) and [Gradient Boosted Decision Trees](https://en.wikipedia.org/wiki/Gradient_boosting#Gradient_tree_boosting) (GBDT). XGBoost can also be [distributed](#features) and scale to Terascale data

Contributing to XGBoost
|
|
=========
|
|
XGBoost has been developed and used by a group of active community members. Everyone is more than welcome to contribute. It is a way to make the project better and more accessible to more users.
|
|
* Check out [Feature Wish List](https://github.com/dmlc/xgboost/labels/Wish-List) to see what can be improved, or open an issue if you want something.
|
|
* Contribute to the [documents and examples](https://github.com/dmlc/xgboost/blob/master/doc/) to share your experience with other users.
|
|
* Please add your name to [CONTRIBUTORS.md](CONTRIBUTORS.md) after your patch has been merged.
|

|
Features
|
|
========
|
|
* Easily accessible in python, R, Julia, CLI
|
|
* Fast speed and memory efficient
|
|
- Can be more than 10 times faster than GBM in sklearn and R
|
|
- Handles sparse matrices, support external memory
|
|
* Accurate prediction, and used extensively by data scientists and kagglers
|
|
- See [highlight links](https://github.com/dmlc/xgboost/blob/master/doc/README.md#highlight-links)
|
|
* Distributed and Portable
|
|
- The distributed version runs on Hadoop (YARN), MPI, SGE etc.
|
|
- Scales to billions of examples and beyond
|
|
|
|
Build
|
|
=======
|
|
* Run ```bash build.sh``` (you can also type make)
|
|
- Normally it gives what you want
|
|
- See [Build Instruction](doc/build.md) for more information
|
|
|
|
Version
|
|
=======
|
|
* Current version xgboost-0.4, a lot improvment has been made since 0.3
|
|
- Change log in [CHANGES.md](CHANGES.md)
|
|
- This version is compatible with 0.3x versions
|

XGBoost in Graphlab Create
|
|
==========================
|
|
* XGBoost is adopted as part of boosted tree toolkit in Graphlab Create (GLC). Graphlab Create is a powerful python toolkit that allows you to do data manipulation, graph processing, hyper-parameter search, and visualization of TeraBytes scale data in one framework. Try the Graphlab Create in http://graphlab.com/products/create/quick-start-guide.html
