Researchers have introduced a novel approach to online convex optimization that utilizes dueling (pairwise comparison) feedback. This method converts the binary preference data into approximate gradients, allowing the application of standard first-order optimization techniques. The proposed reduction successfully transfers regret guarantees, establishing the first known results for this specific setting, including bounds of O(T^{3/4}) for static, adaptive, and dynamic regret. Further improvements yield O(T^{2/3}) rates for smooth objectives and O(sqrt(T log T)) for strongly convex functions. AI
