dist_power: Minkowski distance parameter

In dials: Tools for Creating Tuning Parameter Values

Minkowski distance parameter

Description

Used in parsnip::nearest_neighbor().

Usage

dist_power(range = c(1, 2), 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

This parameter controls how distances are calculated. For example, dist_power = 1 corresponds to Manhattan distance while dist_power = 2 is Euclidean distance.

Examples

dist_power()
