Evaluate Wasserstein distance between samples using dual potentials.
This uses direct estimation of potentials against measures when dual
functions are provided in usual form. This expression is valid for any
cost function.
- Parameters:
src (Array) – Samples from the source distribution, array of shape [n, d].
tgt (Array) – Samples from the target distribution, array of shape [m, d].
- Return type:
float
- Returns:
Wasserstein distance using specified cost function.
