Parameter objects, for the dials package, of the main arguments of
fuzzy_naive_bayes(). They are used automatically by tune when an
argument is marked with tune().
Usage
fuzzy_membership(values = c(TRUE, FALSE))
alpha_cut(range = c(1e-04, 0.1), trans = NULL)
ranking_method(range = c(1L, 5L), trans = NULL)
Arguments
- values
A logical vector of possible values.
- range
A two-element vector with the bounds of the parameter.
- trans
A trans object from the scales package, or NULL.
Value
A param object of the dials package.
Details
fuzzy_membership(): whether the membership functions are used
(argument fuzzy).
alpha_cut(): smallest alpha-cut of the fuzzy parameters (argument
alphacut).
ranking_method(): method used to rank the fuzzy numbers (argument
metd): 1 = Yager, 2 = Q distance, 3 = Thorani, 4 = alpha-order,
5 = GTFN.
These functions require the dials package.
