Re: XGBoost Installation

Which unofficial version do you mean? Both, RPlugin and wekaPython, are
official packages, and both enable you to use XGBoost. With the RPlugin,
you need to use XGBoost through the MLRClassifier and select XGBoost as the
base learner (the first time you select this base learner, it will try to
install it in R, which may take a while). Similarly, with wekaPython, you
also need to use the corresponding ScikitLearnClassifier in WEKA with
XGBoost as the base learner (and you need to have XGBoost installed in your
relevant Python environment, which you may need to do manually).

The easiest way to use XGBoost in WEKA is probably through the RPlugin
because the only manual work you (normally) need to do is to install R.

There might be an unofficial WEKA package for XGBoost out there, but it may
not be maintained.

Cheers,
Eibe
