LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

Reproducibility Variable Result LLM Response
Research Type Theoretical Here, we derive bandit algorithms for some strongly convex sets beyond ℓp balls that enjoy pseudo-regret bounds of O(n T). This result provides new elements for the open question in (Bubeck and Cesa-Bianchi, 2012, 5.5.). When the action set is q-uniformly convex but not necessarily strongly convex (q > 2), we obtain pseudo-regret bounds O(n1/q T 1/p) with p s.t. 1/p + 1/q = 1. These pseudo-regret bounds are competitive with the general O(n T) for a time horizon range that depends on the degree q > 2 of the set s uniform convexity and the dimension n of the problem.
