8.16.4.8. sklearn.metrics.pairwise.kernel_metrics

sklearn.metrics.pairwise.kernel_metrics()

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:
metric Function
‘linear’ sklearn.pairwise.linear_kernel
‘poly’ sklearn.pairwise.polynomial_kernel
‘polynomial’ sklearn.pairwise.polynomial_kernel
‘rbf’ sklearn.pairwise.rbf_kernel
‘sigmoid’ sklearn.pairwise.sigmoid_kernel
