- ImplicitDiff.first_order_conditions(prob, f, g, lse_mode)#
Compute vector of first order conditions for the reg-OT problem.
The output of this vector should be close to zero at optimality. Upon completion of the Sinkhorn forward pass, its norm (using the norm parameter defined using
norm_error) should be below the threshold parameter.
This error will be itself assumed to be close to zero when using implicit differentiation.
