New algorithm boosts online convex optimization guarantees

Researchers have developed a new projection-based algorithm for constrained online convex optimization that significantly improves performance. The algorithm achieves logarithmic regret and cumulative constraint violation for strongly convex losses, an exponential improvement in constraint violation. For general convex losses, it maintains optimal regret while improving constraint violation bounds. AI

    Improved Guarantees for Constrained Online Convex Optimization via Self-Contraction

    We consider Constrained Online Convex Optimization (COCO) with adversarially chosen constraints. At each round, the learner chooses an action before observing the loss and constraint function for that round. The goal is to achieve small static regret against the best point satisf…
