Support vector machine parameters — cost • dials

Parameters related to the SVM objective function(s).

Usage

cost(range = c(-10, 5), trans = log2_trans())

svm_margin(range = c(0, 0.2), 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::log10_trans() or scales::reciprocal_trans(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

Examples

cost()
#> Cost (quantitative)
#> Transformer: log-2 [1e-100, Inf]
#> Range (transformed scale): [-10, 5]
svm_margin()
#> Insensitivity Margin (quantitative)
#> Range: [0, 0.2]
