Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

Reproducibility Variable Result LLM Response
Research Type Theoretical In this paper, we answer this question in a strongly affirmative sense. We propose an efficient algorithm that achieves O(T 1 3 ) ℓ2-swap multicalibration error (both in high probability and expectation). On propagating this bound onward, we obtain significantly improved rates for ℓ1-swap multicalibration and swap omniprediction for a loss class of convex Lipschitz functions. In particular, we show that our algorithm achieves O(T 2 3 ) ℓ1-swap multicalibration and swap omniprediction errors, thereby improving upon the previous best-known bound of O(T 7 8 ). As a consequence of our improved online results, we further obtain several improved sample complexity rates in the distributional setting. In particular, we establish a O(ε 3) sample complexity of efficiently learning an ε-swap omnipredictor for the class of convex and Lipschitz functions, O(ε 2.5) sample complexity of efficiently learning an ε-swap agnostic learner for the squared loss, and O(ε 5), O(ε 2.5) sample complexities of learning ℓ1, ℓ2-swap multicalibrated predictors against linear functions, all of which significantly improve on the previous best-known bounds.
