Robust accelerated primal-dual methods for computing saddle points


Xuan Zhang, Necdet Serhat Aybat, Mert Gürbüzbalaban

SIAM Journal on Optimization, 34(1), pp. 1097–1130, 2024.

In brief

Accelerated primal–dual methods solve saddle-point problems quickly but, like momentum methods, amplify gradient errors. For strongly convex–strongly concave problems the paper quantifies that amplification as a robustness measure, computes it for the accelerated primal–dual family, and shows how to choose parameters on the speed–robustness frontier — the saddle-point counterpart of the trade-off for momentum methods.
