A Symplectic Analysis of Alternating Mirror Descent

no code implementations6 May 2024 Jonas Katona, Xiuyuan Wang, Andre Wibisono

We derive new error bounds on the MH when truncated at orders in the stepsize in terms of the number of iterations, $K$, and use these bounds to show an improved $\mathcal{O}(K^{1/5})$ total regret bound and an $\mathcal{O}(K^{-4/5})$ duality gap of the average iterates for AMD.
