WebIt is defined as L: K × K ¯ → R and computes a real value for the pair. All loss functions implemented in PyKEEN induce an auxillary loss function based on the chosen interaction function L ∗: R × R → R that simply passes the scores through.

In statistics, the Bhattacharyya distance measures the similarity of two probability distributions. It is closely related to the Bhattacharyya coefficient which is a measure of the amount of overlap between two statistical samples or populations.
