Description

Parameter types for LightGBM.

Parameter details are documented in the LightGBM documentation.

Note that some of the parameters listed in the documentation are not exposed here since they're set implicitly through other parts of the API. For instance, the task param is set in the LightGBM.Model API, and the header param is set in the LightGBM.DataSet API.
