Researchers have introduced the Distributionally Robust Schrödinger Bridge (DRSB), a novel approach to learning stochastic transport between distributions that enhances robustness against shifts in the initial distribution. Unlike standard Schrödinger bridges, DRSB learns a single controller that accounts for uncertainty in the initial distribution by minimizing a worst-case objective. This method utilizes variational formulations and alternating algorithms, incorporating Wasserstein and Sinkhorn variants for gradient approximation. Experiments demonstrate improved robustness to input perturbations compared to standard methods, with a slight trade-off in nominal performance. AI
