distance_metrics

sklearn.metrics.pairwise.distance_metrics()

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	Function
‘cityblock’	metrics.pairwise.manhattan_distances
‘cosine’	metrics.pairwise.cosine_distances
‘euclidean’	metrics.pairwise.euclidean_distances
‘haversine’	metrics.pairwise.haversine_distances
‘l1’	metrics.pairwise.manhattan_distances
‘l2’	metrics.pairwise.euclidean_distances
‘manhattan’	metrics.pairwise.manhattan_distances
‘nan_euclidean’	metrics.pairwise.nan_euclidean_distances
