penalty

Amount of regularization/penalization

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())

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

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