A numeric parameter function representing the amount of penalties (e.g. L1, L2, etc) in regularized models.
penalty(range = c(-10, 0), trans = transform_log10())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.
A trans object from the scales package, such as
scales::transform_log10() or scales::transform_reciprocal(). 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.
