XGBoost Plugin Example

This folder provides an example of implementing xgboost plugin.

There are three steps you need to do to add a plugin to xgboost

  • Create your source .cc file, implement a new extension
  • Register this extension to xgboost via a registration macro
    • In this example XGBOOST_REGISTER_OBJECTIVE in this line
  • Add a line to xgboost/plugin/CMakeLists.txt:
set(PLUGINS_SOURCES ${PLUGINS_SOURCES}
    ${xgboost_SOURCE_DIR}/plugin/example/custom_obj.cc PARENT_SCOPE)

Then you can test this plugin by using objective=mylogistic parameter.
