ott.initializers.linear.initializers.SortingInitializer.init_fu

SortingInitializer.init_fu(ot_prob, lse_mode, rng=None, init_f=None)

Apply DualSort algorithm.

Parameters:

• ot_prob (LinearProblem) – OT problem between discrete distributions.

• lse_mode (bool) – Return potential if True, scaling if False.

• rng (Optional[Array]) – Random number generator for stochastic initializers, unused.

• init_f (Optional[Array]) – potential f, array of size [n,]. This is the starting potential, which is then updated to make the init potential, so an init of an init.

Return type:

Array

Returns:

potential/scaling f_u, array of size [n,].
