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", ...).
num_leaves(range = c(5, 100), trans = NULL)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.
A trans object from the scales package, such as
scales::transform_log10() or scales::transform_reciprocal(). If not provided,
the default is used which matches the units used in range. If no
transformation, NULL.
"lightbgm" is an available engine in the parsnip extension package bonsai
