Robust Sublinear Convergence Rates for Iterative Bregman Projections
A proof blueprint establishes robust O(1/k) rates for entropic Bregman projections that scale linearly in the inverse regularization strength, instantiated as a new flow-Sinkhorn method for graph W1 with O(p diameter^3 / ε^4) complexity.
