sklearn.metrics.pairwise.kernel_metrics

sklearn.metrics.pairwise.kernel_metrics() [source]

Valid metrics for pairwise_kernels.

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

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