distance_metrics#

sklearn.metrics.pairwise.distance_metrics()[source]#

Valid metrics for pairwise_distances.

This function simply returns the valid pairwise distance metrics. It exists to allow for a description of the mapping for each of the valid strings.

The valid distance metrics, and the function they map to, are:

metric
