c5_parameters

Parameters for possible engine parameters for C5.0

Description

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 = log10_trans())

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.
`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`.
`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.
