ott.solvers.quadratic.gw_barycenter.GWBarycenterState#

class ott.solvers.quadratic.gw_barycenter.GWBarycenterState(cost=None, x=None, a=None, errors=None, costs=None, costs_bary=None, gw_convergence=None)[source]#

State of the GW barycenter problem.

Parameters:

  • cost (Optional[Array]) – Barycenter cost matrix of shape [bar_size, bar_size].

  • x (Optional[Array]) – Barycenter features of shape [bar_size, ndim_fused]. Only used in the fused case.

  • a (Optional[Array]) – Weights of the barycenter of shape [bar_size,].

  • errors (Optional[Array]) – Array of shape [max_iter, num_measures, quad_max_iter, lin_outer_iter] containing the GW errors at each iteration.

  • costs (Optional[Array]) – Array of shape [max_iter,] containing the cost at each iteration.

  • costs_bary (Optional[Array]) – Array of shape [max_iter, num_measures] containing the cost between the individual measures and the barycenter at each iteration.

  • gw_convergence (Optional[Array]) – Array of shape [max_iter,] containing the convergence of all GW problems at each iteration.

Methods
