Parameters for possible engine parameters for C5.0

These parameters are auxiliary to tree-based models that use the "C5.0" engine. They correspond to tuning parameters that would be specified using set_engine("C5.0", ...).

Usage

confidence_factor(range = c(-1, 0), trans = transform_log10())

no_global_pruning(values = c(TRUE, FALSE))

predictor_winnowing(values = c(TRUE, FALSE))

fuzzy_thresholding(values = c(TRUE, FALSE))

rule_bands(range = c(2L, 500L), 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::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.
values: For no_global_pruning(), predictor_winnowing(), and fuzzy_thresholding() either TRUE or FALSE.

Details

To use these, check ?C50::C5.0Control to see how they are used.
