sklearn.metrics.pairwise.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:
