New BAGEL algorithm tackles adversarial COCO with Separation Oracle access

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new algorithm called BAGEL for adversarial Constrained Online Convex Optimization (COCO). This algorithm is designed to perform well even when the action set can only be accessed through a Separation Oracle (SO), rather than more powerful oracles like Projection Oracle (PO) or Linear Optimization Oracle (LOO). BAGEL achieves a theoretical balance between low regret and low cumulative constraint violation, using a near-linear number of SO calls. AI

IMPACT Introduces a new theoretical framework for optimization problems with limited oracle access, potentially impacting algorithm design in machine learning.

    BAGEL: Adversarially Constrained Online Convex Optimization under Separation Oracle Access

    arXiv:2502.16744v3 Announce Type: replace Abstract: In adversarial Constrained Online Convex Optimization (COCO), a learner selects actions from a fixed convex set while seeking both low regret and low cumulative constraint violation (CCV) under time-varying constraints. We ask w…
