A numeric parameter function representing the amount of penalties (e.g. L1, L2, etc) in regularized models.

penalty(range = c(-10, 0), trans = log10_trans())

## Arguments

range A two-element vector holding the defaults for the smallest and largest possible values, respectively. Note that these are in transformed units. 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.

## Details

This parameter is used for regularized or penalized models such as parsnip::linear_reg(), parsnip::logistic_reg(), and others.

## Examples

penalty()
#> Amount of Regularization (quantitative)
#> Transformer:  log-10
#> Range (transformed scale): [-10, 0]
