Amount of regularization/penalization

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

Usage

penalty(range = c(-10, 0), trans = transform_log10())

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::transform_log10() or scales::transform_reciprocal(). 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
