Nettetthis is one of the few general results we have for global linear convergence on non-convex problems. 2.1 Relationships Between Conditions As mentioned in the Section … NettetThe aim of this note is to give an elementary proof of linear convergence of the Sinkhorn algorithm for the entropic regularization of multimarginal optimal transport in the setting of general probability spaces. The proof simply relies on (i) the fact that Sinkhorn iterates are bounded, (ii) the strong convexity of the exponential on bounded ...
