arXiv:2606.01764v1 Announce Type: cross Abstract: We revisit the convergence guarantees of the Extragradient (EG) method for unconstrained biaffine min-max optimization. It is known that EG with a fixed stepsize achieves a $\Theta(T^{-1/2})$ last-iterate convergence rate, which is slower than the optimal $\mathcal{O}(T^{-1})$ rate attainable by incorporating additional mechanisms such as anchoring. Motivated by recent advances showing that dynamic stepsizes alone can significantly accelerate gradient descent, we ask whether dynamic stepsizes can similarly accelerate the last-iterate convergenc
The paper builds on recent advancements in dynamic stepsizes for gradient descent, applying similar principles to accelerate min-max optimization, a core technique in AI development.
Improved algorithms for min-max optimization can significantly enhance the efficiency and performance of training generative adversarial networks and other equilibrium models critical to advanced AI.
This research suggests a potential pathway to faster and more stable convergence for certain types of AI models, lowering compute requirements and accelerating development cycles.
