DESCRIPTION

Perl wrapper for XGBoost library. This version only wraps part of the C API.

The documentation can be found in AI::XGBoost::CAPI::RAW

Currently this module need the xgboost binary available in your system. I'm going to make an Alien module for xgboost but meanwhile you need to compile yourself xgboost: https://github.com/dmlc/xgboost
