These parameters are auxiliary to tree-based models that use the "lightgbm" engine. They correspond to tuning parameters that would be specified using set_engine("lightgbm", ...).

## Usage

num_leaves(range = c(5, 100), trans = NULL)

## Arguments

range

A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units.

trans

A trans object from the scales package, such as scales::log10_trans() or scales::reciprocal_trans(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

## Details

"lightbgm" is an available engine in the parsnip extension package bonsai
