Parameters for possible engine parameters for xgboost
Description
These parameters are auxiliary to tree-based models that use the "xgboost"
engine. They correspond to tuning parameters that would be specified using
set_engine("xgboost", ...)
.
Usage
scale_pos_weight(range = c(0.8, 1.2), trans = NULL)
penalty_L2(range = c(-10, 1), trans = transform_log10())
penalty_L1(range = c(-10, 1), trans = transform_log10())
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 |
