Parameters for class weights for imbalanced problems — class_weights • dials

This parameter can be used to moderate how much influence certain classes receive during training.

Usage

class_weights(range = c(1, 10), 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::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

Used in brulee::brulee_logistic_reg() and brulee::brulee_mlp()
